The present disclosure provides an antenna apparatus including a first antenna and a second antenna, in which a coupling capacitance is additionally provided at a space between the first antenna and the second antenna, thereby suppressing a signal radiated by the antenna apparatus from leaking to a rear side of the antenna apparatus through the space, enabling the antenna apparatus to still maintain a high front-to-rear ratio, thereby improving radiation performance of the antenna apparatus.

According to an exemplary embodiment of the present disclosure, as shown in fig. 1, an antenna apparatus may include a first antenna 100, a second antenna 200, and a coupling capacitor 400.

The first antenna 100 may comprise a first reflecting component 110 configured to reflect at least part of the signal radiated by the antenna device, in particular the first reflecting component 110 may reflect at least part of the signal radiated by the first antenna 100 and possibly also part of the signal radiated by the second antenna 200 as described below. The first reflecting surface 111 of the first reflecting member 110 is disposed toward the front side of the antenna device to reflect a signal directed backward forward. The first reflecting surface 111 may be a plane or a curved surface according to different requirements. Hereinafter, the first reflection surface 111 will be described as an example of a plane, but it is understood that embodiments of the present disclosure are not limited thereto. In some embodiments, the first reflection part 110 may be formed of a conductive metal material, or the first reflection part 110 may include other materials and a metal thin film deposited on a surface of the material, etc.

As shown in fig. 1, the first antenna 100 may also include one or more antenna elements 120. The antenna element 120 protrudes forward from the first reflection surface 111. Part of the signal radiated forward by the antenna element 120 will be radiated directly into the front space, while part of the signal radiated backward by the antenna element 120 will be reflected forward by at least the first reflecting surface 111 (and part of the signal may be reflected by the second reflecting surface 211 described below). Antenna element 120 may include only a single type of antenna element corresponding to a single frequency band, or may include multiple types of antenna elements corresponding to multiple frequency bands or having other different properties. Furthermore, the plurality of antenna elements 120 may be arranged in various ways so that the signal radiated by the first antenna 100 may meet specific requirements.

In a specific embodiment, as shown in fig. 2, the first antenna 100 may include a plurality of first antenna elements 121 arranged in an array and a plurality of second antenna elements 122 arranged in an array. The first antenna element 121 may be configured to radiate signals in a first frequency band and the second antenna element 122 may be configured to radiate signals in a second frequency band. In some embodiments, at least some of the frequencies in the second frequency band are higher than the highest frequencies in the first frequency band. That is, the first antenna 100 may radiate respective signals in two different frequency bands through the first antenna element 121 and the second antenna element 122, respectively. For example, the first antenna element 121 may be configured to radiate 617-and 960 MHz-band signals or portions thereof, and the second antenna element 122 may be configured to radiate 1695-and 2690 MHz-band signals or portions thereof. In the depicted embodiment, two columns of first antenna elements 121 and six columns of second antenna elements 122 are provided.

Similarly, as shown in fig. 1, the second antenna 200 may comprise a second reflecting component 210 configured to reflect at least a part of the signal radiated by the antenna device, in particular, the second reflecting component 210 may reflect at least a part of the signal radiated by the second antenna 200, and possibly also a part of the signal radiated by the first antenna 100. The second reflection surface 211 of the second reflection part 210 is disposed toward the front side of the antenna apparatus to radiate a signal forward. The second reflecting surface 211 may be a plane or a curved surface according to different requirements. Hereinafter, the second reflection surface 211 will be described as an example of a plane, but it is understood that embodiments of the present disclosure are not limited thereto. In some embodiments, the second reflection part 210 may be formed of a conductive metal material, or the second reflection part 210 may include other materials and a metal thin film deposited on a surface of the material, etc.

As shown in fig. 1, the second antenna 200 may further include one or more antenna elements 220, the one or more antenna elements 220 protruding forward from the second reflecting surface 211. In this case, part of the signal radiated forward by the antenna element 220 will be radiated directly into the front space, while part of the signal radiated backward by the antenna element 220 will be reflected forward by at least the second reflecting surface 211 (and part of the signal may be reflected by the first reflecting surface 111). Antenna element 220 may include only a single type of antenna element corresponding to a single frequency band, or may include multiple types of antenna elements corresponding to multiple frequency bands or having other different properties. Furthermore, the plurality of antenna elements 220 may be arranged in various ways, so that the signal radiated by the second antenna 200 may meet specific requirements.

In one embodiment, as shown in fig. 2, the second antenna 200 may include a plurality of third antenna elements 223 arranged in an array and a plurality of fourth antenna elements 224 arranged in an array. The third antenna element 223 may be configured to radiate signals in a third frequency band and the fourth antenna element 224 may be configured to radiate signals in a fourth frequency band. In a specific example, the third frequency band is the first frequency band. That is, in this case, the first antenna element 121 in the first antenna 100 and the third antenna element 223 in the second antenna 200 participate in radiating signals in the first frequency band in common. In other words, for signals in the first frequency band, the first antenna 100 and the second antenna 200 can be regarded as a complete antenna. In some embodiments, at least some of the frequencies in the fourth frequency band are higher than the highest frequencies in the third frequency band or the first frequency band. The fourth frequency band may be the same as or different from the second frequency band. In the particular embodiment shown in fig. 2, the second antenna 200 may radiate respective signals in two different frequency bands via the third 223 and fourth 224 antenna elements, respectively. For example, the third antenna element 223 and the fourth antenna element 224 may be arranged in a 2L4H layout as shown in fig. 2, wherein the column formed by the third antenna element 223 is located between two columns of the fourth antenna element 224.

As shown in fig. 1 and 2, the first antenna 100 and the second antenna 200 may be separately provided and electrically connected through, for example, a blind-mate connector or the like. Accordingly, there is a space 300 between the first reflection part 110 and the second reflection part 210. The first antenna 100 and the second antenna 200 may be arranged in an up-down direction (i.e., may be vertically stacked). As shown in fig. 2, the second antenna 200 is disposed below the first antenna 100. It is understood that the first antenna 100 and the second antenna 200 may be arranged in other manners (for example, in a left-right direction, etc.), and are not limited herein.

In some embodiments, as shown in fig. 1 and 2, the first reflective surface 111 and the second reflective surface 211 may be disposed coplanar with each other, thereby helping to avoid mutual interference between the first antenna 100 and the second antenna 200 and improving the radiation effect of the antenna device.

In some embodiments, both the first antenna 100 and the second antenna 200 may be passive antennas. Alternatively, in other embodiments, at least one of the first antenna 100 and the second antenna 200 may include an active device 500 (see fig. 3). The active device 500 may include circuits or components such as a receiving module, an amplifying module, and a power supply module. The active device 500 may be disposed at a rear side of the first and/or second reflection parts 110 and/or 210 with respect to the first and/or second reflection parts 110 and 210.

In the particular embodiment shown in fig. 3, the first antenna 100 may include an active device 500, and the active device 500 may be electrically connected to at least some of the antenna elements 120 in the first antenna 100. For example, the active device 500 may be electrically connected with the second antenna element 122 in the first antenna 100 shown in fig. 2. In other embodiments, the active device 500 may also be electrically connected with the second antenna 200, or the first active device 500 may be included in the first antenna 100 and the second active device 500 may be included in the second antenna 200.

As shown in fig. 3 and 4, the first antenna 100 may include a first radome 130, and/or the second antenna 200 may include a second radome 230. The radome 130, 230 may protect the antenna 100, 200 from the external environment. The radome 130, 230 is substantially transparent to electromagnetic radiation in the operating frequency band of the respective antenna 100, 200 and can be mechanically subjected to the harsh environment of the outside to avoid damage to the antenna 100, 200 from rain, ice, snow, sand, and solar radiation. In the specific embodiment shown in fig. 3 and 4, the first reflection part 110 and the antenna element 120 of the first antenna 100 may be disposed inside the first antenna cover 130, and the second reflection part 210 and the antenna element 220 of the second antenna 200 may be disposed inside the second antenna cover 230. Furthermore, the active device 500 of the first antenna 100 may be disposed outside the first antenna cover 130 at the rear side of the first antenna cover 130.

As shown in fig. 1, the coupling capacitor 400 may include a first plate 410 and a second plate 420. The first plate 410 and the second plate 420 may be disposed near the space 300, for example, the first plate 410 is disposed on the first reflecting surface 111 of the first reflecting member 110 near the space 300, and the second plate 420 is disposed on the second reflecting surface 211 of the second reflecting member 210 near the space 300. The coupling capacitor 400 can suppress the signal radiated from the antenna device from leaking to the rear side of the antenna device through the space 300. Specifically, the influence of the gap 300 on the signal transmission will be greatly reduced due to the presence of the coupling capacitor 400, and when the capacitance value of the coupling capacitor 400 is sufficiently large, the signal transmission will be similar to the signal transmission in the absence of the gap 300 (i.e., the antenna apparatus has a complete reflecting member or surface).

The capacitance of the coupling capacitor 400 is generally determined by the structural parameters, which may specifically include the effective capacitance area and the effective capacitance spacing of the coupling capacitor 400. The effective capacitance area may correspond to an area where part or all of the first plate 410 overlaps part or all of the second plate 420, and the effective capacitance pitch may be a distance between the overlapping portions of the first plate 410 and the second plate 420. In many cases, the spacing between the first antenna 100 and the second antenna 200 in the antenna apparatus may be fixed, and this effectively fixes the effective capacitive spacing. Therefore, the capacitance value of the coupling capacitor 400 can be adjusted to an appropriate value by adjusting the effective capacitance area, i.e., the area where the first plate 410 overlaps the second plate 420. Although sufficient capacitance values may generally be obtained by increasing the overlapping area, the increased size of the first plate 410 and the second plate 420 may put high demands on the space in the antenna device for arranging the coupling capacitor 400. Thus, space limitations may limit the size of the first plate 410 and the second plate 420, thereby limiting the effective capacitive area.

In general, the effect of the interval 300 is more pronounced for relatively low frequency signals than for relatively high frequency signals. Therefore, in determining the structural parameters of the coupling capacitor 400, it may be configured according to the lowest frequency partial signal among the signals radiated by the antenna device. While the radiation effect of the lowest frequency partial signal can meet the requirement, the radiation effect of the higher frequency partial signal can also meet the requirement generally.

In some embodiments, as shown in fig. 5 to 12, the first plate 410 and the second plate 420 are parallel to each other to fully utilize the limited space as much as possible, so that the capacitance value of the coupling capacitor 400 is large enough to improve the radiation effect of the antenna device.

In some embodiments, as shown in fig. 5-12, the first plate 410 and the second plate 420 are disposed diametrically opposite each other. Compared with the way that the first pole plate 410 and the second pole plate 420 are arranged in a staggered manner, such an arrangement can obtain a larger effective capacitance area, and thus a larger capacitance value, so as to improve the radiation effect of the antenna device.

In some embodiments, as shown in fig. 5 to 12, the first plate 410 may be vertically disposed with respect to the first reflective surface 111, and the second plate 420 may be vertically disposed with respect to the second reflective surface 211, thereby facilitating a simplified manufacturing process of the coupling capacitor 400 and improving a radiation effect of the antenna apparatus.

The extending direction of the first plate 410 relative to the first reflecting surface 111 and the extending direction of the second plate 420 relative to the second reflecting surface 211 can be determined according to the arrangement positions of other components and structures in the antenna device, so that the first plate 410 and the second plate 420 are prevented from causing adverse effects on other components of the antenna device. In order to make the capacitance value of the coupling capacitor 400 as large as possible, the first and second plates 410 and 420 may extend in the same direction, although embodiments of the present disclosure are not limited thereto.

In some embodiments, as shown in fig. 5, 8 and 11, the first plate 410 may extend toward the front side of the antenna device relative to the first reflective surface 111, and the second plate 420 may extend toward the front side of the antenna device relative to the second reflective surface 211.

In some embodiments, as shown in fig. 6 and 9, the first plate 410 may extend toward the rear side of the antenna device with respect to the first reflective surface 111, and the second plate 420 may extend toward the rear side of the antenna device with respect to the second reflective surface 211.

In some embodiments, as shown in fig. 7, 10 and 12, the first plate 410 may extend toward both the front and rear sides of the antenna device with respect to the first reflection surface 111, and the second plate 420 may extend toward both the front and rear sides of the antenna device with respect to the second reflection surface 211 to further increase the capacitance value of the coupling capacitor 400.

The first and second electrode plates 410 and 420 may be formed in various ways.

In some embodiments, as shown in fig. 5 to 7, the first reflective part 110 may include a first conductive plate 410a disposed at an angle with respect to the first reflective surface 111, the first conductive plate 410a configured to form a first plate 410; and the second reflective part 210 may include a second conductive plate 420a disposed at an angle with respect to the second reflective surface 211, and the second conductive plate 420a may be configured to form a second pole plate 420.

Specifically, the first polar plate 410 may be formed by bending the first reflective component 110 at a first angle with respect to the first reflective plate 112, wherein the first reflective plate 112 is a planar plate including the first reflective surface 111; and the second plate 420 may be formed by bending the second reflection part 210 at a second angle with respect to the second reflection plate 212, wherein the second reflection plate 212 is a planar plate including the second reflection surface 211. That is, the first reflection plate 112 may be integrally formed with the first plate 410, and the second reflection plate 212 may be integrally formed with the second plate 420, thereby simplifying a manufacturing process of the coupling capacitor 400.

In some embodiments, the first angle may be a right angle, and the second angle may be a right angle, thereby contributing to simplifying the manufacturing process of the coupling capacitor 400 and improving the radiation effect of the antenna device.

In some embodiments, the first reflective member 110 is disposed entirely within the first antenna cover 130 and the second reflective member 210 is disposed entirely within the second antenna cover 230, and accordingly, the first plate 410 and the second plate 420 of the coupling capacitor 400 may be disposed within the first antenna cover 130 and the second antenna cover 230, respectively. The first antenna cover 130 and the second antenna cover 230 will not adversely affect the coupling effect of the coupling capacitor 400, and can protect the first plate 410 and the second plate 420, thereby improving the radiation effect of the antenna device.

In some embodiments, as shown in fig. 8-10, the antenna apparatus may include a first capacitive component 410b and a second capacitive component 420 b. Wherein the first capacitive part 410b is an independent structure with respect to the first reflective part 110, at least a portion of the first capacitive part 410b is configured to form the first plate 410, the second capacitive part 420b is an independent structure with respect to the second reflective part 210, and at least a portion of the second capacitive part 420b is configured to form the second plate 420.

Further, the first capacitor part 410b may include a first fixing portion and a first plate 410 connected to each other, wherein the first fixing portion may be configured to be mechanically connected to the first reflection part 110, and the second capacitor part 420b may include a second fixing portion and a second plate 420 connected to each other, wherein the second fixing portion may be configured to be mechanically connected to the second reflection part 210.

In the specific example shown in fig. 8 to 10, the first fixing portion may include a first fixing plate 412, wherein the first fixing plate 412 may be connected to the first reflecting member 110 in parallel to the first reflecting surface 111, and the second fixing portion may include a second fixing plate 422, wherein the second fixing plate 422 may be connected to the second reflecting member 210 in parallel to the second reflecting surface 211.

It is understood that in other specific examples, the first fixing portion and/or the second fixing portion may include other components or assemblies for connection, such as screws, bolts, and snaps.

The different ways of arranging the first plate 410 and the second plate 420 of the coupling capacitor 400 may also be combined with each other. In a specific example as shown in fig. 11, the first plate 410 of the coupling capacitor 400 may be a portion of the first reflective part 110 formed by bending the first reflective part 110, and the second plate 420 may be formed of a portion of the second capacitive part independent of the second reflective part 210.

In the specific example shown in fig. 12, the first plate 410 may also be formed of two parts, wherein the first part 410c is formed by bending the first reflective part 110, and the second part 410d is formed by at least a part of the first capacitive part independent of the first reflective part 110. Similarly, the second plate 420 may also be formed of two parts, wherein the first part 420c is formed by bending the second reflective part 210 and the second part 420d is formed by at least a part of the first capacitive part independent of the second reflective part 210.

It is understood that the above embodiments may be combined in other ways, and are not described in detail herein.

According to another exemplary embodiment of the present disclosure, as shown in fig. 13, a coupling capacitor 400 in an antenna apparatus may be formed of a first reflective part 110 of a first antenna, a second reflective part 210 of a second antenna, and an additionally provided capacitive plate 430.

The basic configuration of the first antenna and the second antenna in the antenna apparatus may refer to the above description, which is not repeated here, and differences of the exemplary embodiment from the previously described embodiments will be emphasized hereinafter.

Wherein the capacitive plate 430 is disposed near the space 300 between the first and second reflection parts 110 and 120 to form a coupling capacitance 400 with at least one of the first and second reflection parts 110 and 120 to suppress a signal radiated from the antenna device from leaking to the rear side of the antenna device through the space 300.

Similarly, the capacitance of the coupling capacitor 400 is generally determined by its structural parameters, which may specifically include the effective capacitance area and the effective capacitance spacing of the coupling capacitor 400. The effective capacitance area may be based on a plate area of the capacitance plate 430, a width of the space 300 between the first reflection part 110 and the second reflection part 210, and the like, and the effective capacitance pitch may be obtained according to parameters such as a first pitch between the capacitance plate 430 and the first reflection part 110, a second pitch between the capacitance plate 430 and the second reflection part 210, and the like.

In some embodiments, as shown in fig. 13, the capacitor plate 430 is parallel to at least one of the first and second reflection parts 110 and 210 to increase the capacitance value of the coupling capacitor 400 as much as possible and improve the radiation effect of the antenna apparatus.

In some embodiments, as shown in fig. 13, the projection of the capacitive plate 430 onto the plane where the first reflective element 110 and the second reflective element 210 are located covers the space 300, thereby minimizing signal leakage from the space 300 to the rear side of the antenna device.
