Antenna combination device

This case is related to an antenna combination device.

Nowadays, the cost control of electronic products is becoming more and more strict, and the cost of antenna design is also becoming more and more stringent. Most of the existing antenna design methods are to wrap the antenna or set it on a plastic structural part, and connect the antenna to a conductive material such as copper foil or aluminum foil for grounding. This design method uses structural parts, so It is necessary to open a mold to make plastic structural parts, which will greatly increase the production cost, and there is a larger design space requirement due to the grounding area requirement. Therefore, under the condition that the size of the antenna remains unchanged, it is necessary to consider effective cost saving and area reduction.

The present application provides an antenna assembly device, which includes a metal casing, at least one metal lap and at least one antenna. The metal lap piece is located on the inner surface of the metal casing. The antenna is installed on the metal lap piece to keep a distance between the antenna and the metal casing. The antenna includes a grounding part and a first radiating part. The metal laps The element is in contact with the grounding part to form an electrical connection.

In summary, the antenna assembly device of this case does not change the size of the existing antenna. The metal lap is directly installed on the metal casing to install the antenna, so as to save the expensive mold opening cost of the plastic mold. This reduces the area required for antenna grounding. Therefore, this case can provide an antenna assembly device with a simpler structural design and convenient assembly, so that the antenna has good grounding characteristics and maintains good antenna efficiency.
