Radiation unit of TD-LTE intelligent antenna

Abstract

The invention belongs to the technical field of antennas, and provides a radiation unit of a TD-LTE intelligent antenna. The radiation unit comprises two feed piece assemblies, a die-casting unit and a medium gasket. The die-casting unit is provided with at least two pairs of dipoles. Each dipole is provided with a radiation arm and supporting arms, wherein the radiation arm and the supporting arms are connected into a whole, a hole is formed in the middle of one of the supporting arms, and the corresponding feed piece assembly is arranged in the hole in a penetrating mode. Each feed piece assembly comprises three thermoplastic media and a feed piece. The middle of each feed piece assembly is folded in two to form a shape approximate to a right angle. The two feed piece assemblies are inserted into the die-casting unit in a crossing mode and fixed to the die-casting unit through barb structures. The die-casting unit is connected with the thermoplastic media in a clamped mode. The medium gasket is arranged at the bottom of the die-casting unit and makes contact with a reflection plate. In this way, by means of the radiation unit, the effects of reducing welding points and being high in machining efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a broadband dual-polarization radiation unit of a TD-LTE smart antenna. Background technique [0002] With the issuance of 4G licenses in China, the construction of TD-LTE base stations will usher in a blowout peak in the next few years. At the same time, operators are paying more and more attention to quality in their requirements for antennas, and high-quality antennas will occupy the main market. [0003] On the one hand, it is the pressure on production capacity brought about by the large demand in the market, and on the other hand, the market pays more and more attention to quality. For the antenna, on the one hand, it needs to be convenient for rapid assembly in batches, on the other hand, it must have excellent radiation performance and stable and reliable electrical performance. [0004] As a basic component of a dual-polarized base station antenna, the radiating unit ...

AI Technical Summary

Problems solved by technology

However, the existing dual-polarization radiation unit has poor radiation performance, complex structure, and troublesome assembly, which can no longer meet the needs of the current stage.

[0005] In summary, the existing technology obviously has inconvenience and defects in actual use, so it is necessary to improve it.
