Antenna and wireless signal transceiver system

Abstract

The invention provides an antenna and a wireless signal transceiver system, and relates to the technical field of antennas. The influence of the internal material of an insulating substrate on the radiation efficiency, bandwidth and consistency of an antenna can be reduced. The antenna provided by an embodiment of the invention comprises an insulating substrate which consists of a first surface and a second surface opposite to the first surface. A radiating element layer is formed on the first surface. A hollowed-out area is formed inside the insulating substrate. The inner wall of the hollowed-out area is isolated from the first surface. The radiating element layer is connected with a grounding connector and a feeding connector. The antenna and the wireless signal transceiver system can be used in an indoor coverage system.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to an antenna and a wireless signal transceiving system. Background technique [0002] With the rapid increase of mobile users in cities, the traffic density is also increasing, and the requirements for signal coverage are also rising. The local network capacity in some places cannot meet the needs of users, and the above problems can be solved well by setting up indoor coverage systems (small stations). The principle is to use the indoor distributed antenna system to evenly distribute the signal of the mobile base station in every corner of the room, so as to ensure ideal signal coverage in the indoor area. [0003] An existing antenna such as figure 1 As shown, it includes a plastic support block 01, the upper surface of the plastic support block 01 is provided with a sheet metal radiator 02, and the lower surface of the plastic support block 01 is fixedly connected with PCB03 ...

AI Technical Summary

Problems solved by technology

[0004] The existing antenna has at least the following problems: Since the plastic support block 01 is a solid block structure, when the electromagnetic field generated by the antenna passes through the plastic support block 01, induced charges will be generated in the inner area of ​​the plastic support block 01, thereby weakening the The electromagnetic field radiated by the antenna will have a certain impact on the radiation efficiency bandwidth of the antenna; in the batch production of the antenna, due to the limitation of the production conditions, the material density of the plastic support block 01 of each batch of antennas, the impurities in the material It is not easy to maintain the same quality, which will also affect the consistency of the antenna (the consistency here refers to the consistency of the standing wave and intermodulation, that is, the closeness of the standing wave and intermodulation test values ​​of different batches of antennas) degree)
