Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It will be understood that when an element is referred to as being "electrically connected" to another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "electrically connected" to another element, it can be connected by contact, e.g., by wires, or by contactless connection, e.g., by contactless coupling.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be mutually exclusive without conflict.

Referring to fig. 1 and fig. 2, an antenna assembly 100 for an electronic device 200 is provided. The antenna assembly 100 may be communicatively coupled to the electronic device 200. The antenna assembly 100 serves as an antenna module of the electronic device 200, so that the electronic device 200 transmits and receives radio waves through the antenna assembly 100, and then transmits or exchanges wireless signals with an external device.

In this embodiment, the electronic device 200 may be a terminal or a mobile device such as a smart phone, a tablet computer, a notebook computer, or a desktop computer. In this embodiment, the external device may be a base station.

In the present embodiment, the antenna assembly 100 includes a housing 10, at least one radiating element 20, and a radio frequency module 30. The housing 10 is used for accommodating the at least one radiation unit 20 and the rf module 30.

In this embodiment, the housing 10 may be an outer shell or a protective cover, such as a mobile phone shell or a mobile phone case. The antenna assembly 100 is independently disposed and communicatively coupled to the electronic device 200.

It is understood that in other embodiments, the housing 10 can be used to be detachably assembled to the electronic device 200 and protect the electronic device 200. That is, the size, dimension, and shape of the housing 10 are matched to the electronic device 200. That is, the antenna assembly 100 may be detachably disposed on a back cover of the electronic device 200, and may be wrapped around the electronic device 200 to protect the electronic device 200. Of course, the housing 10 may be provided independently from the electronic device 200.

It is understood that, in the present embodiment, when the housing 10 serves as a protective cover of the electronic device 200, it may also be a carrier of the radiation unit 20. By arranging the radiation units 20 in the electronic device 200 in the housing 10, not only the number of the radiation units 20 can be increased and the data transmission rate can be increased, but also the positions of the original electronic device 200 where the radiation units 20 are arranged can be left free for mounting other required electronic components.

In the present embodiment, the radiation unit 20 is disposed in the housing 10. The radiation unit 20 is used for receiving signals transmitted by the base station. The radiating element 20 is also used to send signals to the base station. In this way, the transmission and reception of signals between the base station and the electronic apparatus 200 are realized.

In other embodiments, the radiation unit 20 is disposed in the housing 10 and near one side of the electronic device 200.

In this embodiment, the radiation units 20 may be arranged in N × M form to form a corresponding antenna array. Wherein, N and M are positive integers, N, M may be equal or unequal.

In this embodiment, both N and M are 4. That is, the radiation elements 20 constitute a 4 × 4 antenna array, and the number of the radiation elements 20 is sixteen. In one embodiment, the size of the 4 x 4 antenna array formed by the radiation elements 20 is 11 cm x 7 cm.

Of course, in other embodiments, the number of the at least one radiation unit 20 is not limited to sixteen, and the arrangement and the number of the radiation units 20 may also be specifically set according to the shape and the size of the housing 10, for example, other numbers, such as eight, ten or twelve.

It is understood that in the present embodiment, the type of each of the radiation units 20 is various, and the disclosure is not limited thereto.

It is understood that, in the present embodiment, each of the radiation elements 20 in the antenna array is a MIMO antenna. The antenna array may utilize a plurality of the MIMO antennas to transceive signals in common. Similarly, in the present embodiment, by modifying the structure of the radiation units 20, each radiation unit 20 may also form another antenna, for example, a corresponding 5G NR antenna, and thus can operate in a corresponding 5G NR frequency band. The 5G NR frequency band mainly uses two sections of frequencies: FR1 frequency band and FR2 frequency band. The frequency range of the FR1 frequency band is 450MHz-6GHz, also called sub 6GHz frequency band; the frequency range of the FR2 frequency band is 24.25 GHz-52.6 GHz, which is commonly called millimeter wave (mmWave).

In the present embodiment, the rf module 30 is disposed in the housing 10. The radio frequency module 30 is configured to process the signal received or transmitted by the radiation unit 20. Specifically, in the present embodiment, the rf module 30 may include, but is not limited to, a filter, a switch, a power amplifier, a Low Noise Amplifier (LNA), a modem processor, and the like.

In this embodiment, during the process of transmitting and receiving signals, the electronic device 200 may provide power to the antenna assembly 100. In this way, the antenna assembly 100 can be enabled to have no additional power supply added during data transmission.

As described above, when the electronic device 200 performs signal transceiving using the antenna assembly 100, firstly, several of the radiating elements 20 and the radio frequency module 30 are disposed in the housing 10, and the antenna assembly 100 and the electronic device 200 can be communicatively connected, so that the electronic device 200 provides power to the antenna assembly 100. In this way, when the electronic device 200 receives signals through the antenna assembly 100, the radiating unit 20 receives signals transmitted by a base station, and the radio frequency module 30 performs processing such as filtering, amplification, signal demodulation, and control beamforming on the received signals, and then transmits the signals to the electronic device 200.

Similarly, when the electronic device 200 transmits signals through the antenna assembly 100, the rf module 30 performs filtering, modulation, control beam forming, and the like on the signals, and then transmits the signals to the base station through the radiation unit 20.

In this embodiment, the antenna assembly 100 may communicate with the electronic device 200 in the form of millimeter waves (the frequency range corresponding to millimeter waves is 30-300 GHz). It is understood that in the present embodiment, since 16 radiation units 20 perform data communication with the electronic device 200 at the same time, ideally, 16 times the power of a transmission channel (relative to a single radiation unit 20) is required to transmit data, and thus, data communication is achieved with the electronic device 200 through a millimeter wave with a narrow beam and a wide bandwidth.

Specifically, in this embodiment, a millimeter wave antenna (not shown) may be disposed on the radio frequency module 30, and the antenna assembly 100 communicates with the electronic device 200 through the millimeter wave antenna in the form of millimeter waves.

It can be understood that, in the present embodiment, the electronic device 200 transmits and receives signals to and from the base station through the antenna assembly 100, and data transmission efficiency is higher.

It can be understood that in the present embodiment, several of the radiation elements 20 form an antenna array, and the distance between each radiation element 20 meets the relevant requirements of practical applications. It can be understood that when the distance between the two radiation units 20 is too far, the number of the housings 10 is small, and the data transmission efficiency is not high. When the distance between two radiation units 20 is too close, interference may be formed between the antennas, and data transmission may be affected. Therefore, the radiation unit 20 can be arranged as many as possible according to specific requirements without generating interference. Therefore, better data transmission efficiency is achieved.

Referring to fig. 3, fig. 3 shows S parameters of each radiating element 20 in the antenna assembly 100 in the present embodiment at different frequency bands. Obviously, in one of the frequency bands, for example, the 4.14-6.05GHz band, the S parameter is lower than-10 dB, which meets the design requirement of the antenna, and at the frequency point of 4.41GHz, the S parameter is the lowest. Therefore, it can be understood that the radiating element 20 supports data transmission in the 4G or 5G frequency band. It can thus be concluded that the antenna assembly 100 operates in the FR1 frequency band of the 5G NR frequency band.

Referring to fig. 4, fig. 4 is a graph illustrating insertion loss between different radiating elements. Where the curve S (1,2) represents the insertion loss between the first and second radiating elements 20, 20. The S-curve (1,3) represents the insertion loss between the first and third radiating elements 20, 20. S (1,5) represents an insertion loss between the first and fifth radiation elements 20 and 20. S (1,6) represents the insertion loss between the first and sixth radiating elements 20, 20. It will be appreciated that to meet the design requirements of the antenna, the insertion loss should be between-25 dB and-10 dB. It is clear from fig. 4 that the insertion loss between different radiating elements is satisfactory.

In addition, in the antenna assembly 100, when the number of the inserted radiation units 20 is larger, the insertion loss thereof is smaller, and the corresponding transmission efficiency is higher. The electronic device 200 transmits and receives signals to and from the base station through the antenna assembly 100 to transmit data to and from each other at a rate related to the number of antennas of the radiation unit 20 provided in the housing 10. The greater the number of the radiation elements 20, the higher the transmission rate thereof. Of course, the distance between the radiation units 20, i.e. the isolation, needs to be considered, the better the isolation, the smaller the interference between the radiation units 20, the better the data transmission effect.

It can be understood that, in this embodiment, by independently disposing the antenna assembly 100 outside the electronic device 200, the number of the radiation units 20 can be effectively increased, which not only saves the space of the electronic device 200, but also further improves the data transmission rate.

Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the spirit and scope of the invention. Those skilled in the art can also make other changes and the like in the design of the present invention within the spirit of the present invention as long as they do not depart from the technical effects of the present invention. Such variations are intended to be included within the scope of the invention as claimed.
