Background

Antennas and the use of antennas are increasingly required for a variety of applications in various industries. Examples of such applications include mobile phones, wearable devices, portable computers, and communication systems for vehicles (e.g., cars, trains, planes, etc.). However, there are conflicting market demands for such antennas. Users and suppliers require multi-band capabilities but desire antennas that are smaller, hidden and/or placed in non-ideal locations, such as near other metal objects. Other limitations may include the requested bandwidth, the available feed location, and the size of the ground plane to which the antenna may be mounted.

To meet these demands, manufacturers have attempted to optimize antennas by modifying or moving parts to different locations. While these antennas may be effective for wireless communications, there remains a need for alternative antennas that provide adequate communications while occupying less space. In particular, it is increasingly difficult to obtain sufficient bandwidth for smaller antennas, while still providing antennas that are not susceptible to damage during installation and/or use.

The problem to be solved is therefore to provide an antenna arrangement which has sufficient bandwidth but which occupies less space and is not prone to damage during installation or operation.

Disclosure of Invention

The problem is solved by an antenna arrangement comprising a dielectric carrier having a first side and a second side. The antenna device also includes a multi-band antenna having an inner surface and an outer surface. The multi-band antenna includes a first portion and a second portion that are curved with respect to each other. A receiving space is defined along the inner surfaces of the first and second portions. The dielectric carrier is disposed within the receiving space such that the first portion is disposed along a first side of the dielectric carrier and the second portion is disposed along a second side of the dielectric carrier. The dielectric carrier includes at least one protrusion that covers a portion of an outer surface of the multi-band antenna.

In some aspects, the at least one protrusion comprises a locking protrusion extending away from the dielectric carrier. The locking protrusion is configured to deflect to allow the multi-band antenna to be disposed adjacent the dielectric carrier. The locking projection includes a clamping surface that covers a portion of the outer surface. Optionally, the locking protrusion extends away from the second side.

In some aspects, the at least one protrusion comprises a guide protrusion spaced apart from and extending along a surface of the dielectric carrier. The guide protrusion defines a groove between the guide protrusion and a surface of the dielectric carrier. The slot is sized to receive the thickness of the conductive sheet of the multi-band antenna. Optionally, the guide projection extends along the first side.

Detailed Description

Embodiments described herein include an antenna apparatus. The antenna device includes a multi-band antenna and a dielectric carrier configured to support the multi-band antenna. The dielectric carrier includes one or more protrusions that extend over or beyond the multi-band antenna and along the outside of the multi-band antenna to retain the multi-band antenna relative to the dielectric carrier. For example, a multiband antenna has an inner surface extending along and facing a dielectric carrier. The multiband antenna also has an outer surface facing away from the dielectric carrier and may represent the exterior of the antenna device. The protrusion may protrude away from the body of the dielectric carrier and on the outer surface. The protrusion prevents the multi-band antenna from being accidentally removed from the dielectric carrier. When the dielectric carrier and the multi-band antenna are fixed to each other, these two elements may form a modular structure that is configured to be moved as a unit for installation.

Alternatively, the antenna arrangement and/or the multiband antenna may be "low-profile". For example, in some embodiments, the height of the multi-band antenna apparatus is no greater than 20 millimeters. In some embodiments, the antenna apparatus may be part of a larger system. For example, the antenna device may be part of a telematics unit, which is located, for example, within a vehicle (e.g., an automobile). However, it is contemplated that the embodiments set forth herein may have other dimensions and/or other applications.

In the embodiment shown, the antenna device comprises a dielectric carrier molded from a thermoplastic material and a multiband antenna stamped from a conductive sheet. However, it should be understood that the antenna device may be manufactured by other methods, such as Laser Direct Structuring (LDS), two-shot molding (dielectric with copper traces), and/or ink printing. The conductive elements may be formed first and then the dielectric material may be molded around the conductive elements. For example, the conductive element may be stamped from sheet metal, placed within the cavity, and then surrounded by thermoplastic material injected into the cavity.
