Embodiment Construction

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0029] In order to solve the problems that the existing radiating units are generally heavy in weight, do not meet the demands of light weight of large-scale antennas, and the assembly is relatively complicated, which is not suitable for large-scale automatic production. The embodiment of the present invention provides a microstrip radiating unit ...

Abstract

The embodiment of the invention provides a microstrip radiation unit and an array antenna. The microstrip radiation unit comprises a dielectric substrate, a radiation circuit and a feeding circuit, wherein the dielectric substrate is integrally formed by injection molding and comprises a top part, a support part and a welding part, the support part is connected with the top and the welding part, the radiation circuit is arranged on an upper surface of the top part, and the feeding circuit is arranged on a lower surface of the top part and extends to the welding part along the support part. With the microstrip radiation unit and the array antenna, provided by the embodiment of the invention, integration of the radiation unit is achieved, the structure is simple, no assembly is needed, the reliability and the consistency of the radiation unit are improved, and the microstrip radiation unit and the array antenna are more suitable for manufacturing on a large scale. Moreover, the microstrip radiation unit has favorable low profile characteristic, the height of the radiation unit is effectively reduced, the weight of the radiation unit is further reduced, and the lightness of the radiation unit is achieved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of communication, and in particular to a microstrip radiation unit and an array antenna. Background technique [0002] With the rapid development of mobile communication technology, the 5th-generation mobile communication technology (5th-Generation, 5G) applies large-scale antenna technology, and deploys dozens or even hundreds of antenna arrays at the base station to increase network capacity. The large-scale antenna technology in the 5G era turns the antenna into an integrated active antenna (Active Antenna Unit, AAU). The AAU integrates the antenna and the radio remote unit (Radio Remote Unit, RRU). The rise has brought great troubles to the load-bearing and construction of the tower, so the light weight of the antenna has become the most intuitive and most difficult problem to be solved. [0003] The existing radiation unit mainly includes the following three schemes. The first...
