Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of intercom antennas, in particular to a V-band dual-frequency intercom antenna with LTE. Background Art
[0002] The main function of a walkie-talkie is intercom. Unlike mobile phones, they do not require a base station to bridge signals. Instead, they communicate directly through point-to-point calls. However, this also brings a major problem: the call distance is limited, and it is difficult to transmit complex information, such as pictures and videos. Sometimes, it is necessary to transmit video information while also having intercom functions, such as on-site law enforcement by traffic police. Currently, due to size and performance reasons, walkie-talkie antennas generally do not directly add 4G LTE bands to the walkie-talkie antenna. Instead, an external antenna uses the intercom band, and the internal antenna uses the 4G LTE band. This not only achieves the function but also reduces mutual interference. However, because the internal environment of a walkie-talkie is far more harsh than that of smart terminals such as mobile phones, the antenna layout and size are very limited, and the overall cost is relatively high.
[0003] Existing technology allows walkie-talkies to be equipped with both internal and external antennas to transmit video and intercom functions. However, the antennas must be designed separately, which is cumbersome and costly. Furthermore, antenna manufacturers must collaborate with host manufacturers on the design of the walkie-talkie's internal structure. This also complicates the motherboard design, requiring the digital ground plane to be hollowed out and more area to be reserved for feed points, hindering the miniaturization of the walkie-talkie. Therefore, those skilled in the art have provided a V-band dual-band walkie-talkie antenna with LTE to address the issues raised in the background art. Utility Model Content

[0007] As a further solution of the present invention: the connector housing, the insulator, the grounding copper ring and the center pin form a standard 50-ohm SMA connector.
