Problems solved by technology

[0003] At present, base station antenna vibrators are mainly implemented in two forms, die-casting vibrator and PCB vibrator, both of which have their own advantages and disadvantages: Die-casting vibrator is integrally formed, with a high degree of integration, but relatively heavy weight; PCB vibrator is relatively light in weight, but in the antenna There are many assembly processes required during assembly, it is difficult to guarantee the consistency of antenna performance, and the production cost is relatively high
In addition, with the further development of 5G technology, base station antennas will be implemented using large-scale arrays. It is foreseeable that there will be more components, higher complexity, and more cumbersome manual assembly.
Performance consistency is more difficult to guarantee, and this problem needs to be solved urgently

Abstract

The present invention provides a base station antenna unit and a base station antenna. The base station antenna unit includes an integrally formed non-metal structure and a metal pattern formed on the non-metal structure through an LDS (laser direct shaping) or LEP (laser enhanced plating) process, wherein the non-metal structure comprises at least a non-metal substrate, and the metal pattern at least comprises vibrator arms, coupling metal strips and metallized through holes, wherein the vibrator arms are formed at the front surface of the non-metal substrate, the coupling metal strips are formed at the back surface of the non-metal substrate, and the metallized through holes are formed at the connection through holes of the vibrator arms and are connected with the vibrator arms. The base station antenna unit has the advantages of light weight, high surface accuracy and high production consistency.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a base station antenna unit and a base station antenna. Background technique [0002] With the development of base station antenna technology and 5G communication technology, base station antennas not only need to have excellent electrical performance, such as ultra-wideband, high gain, high isolation, high front-to-back ratio and high cross-polarization ratio, but also need to have a low profile, Lightweight mechanical properties, low processing costs, and good electrical performance consistency can meet mass production to meet market demand. [0003] At present, base station antenna vibrators are mainly implemented in two forms, die-casting vibrator and PCB vibrator, both of which have their own advantages and disadvantages: Die-casting vibrator is integrally formed, with a high degree of integration, but relatively heavy weight; PCB vibrator is relativel...
