Antenna and filter connection structure and connection method

Abstract

The invention discloses an antenna and filter connection structure and connection method. According to the invention, an adapter plate is arranged between a calibration plate and a filter on the backsurface of the antenna; a signal path between the filter and the antenna calibration plate is formed through the filter connection structure on the adapter plate and a calibration plate connection bonding pad; the connection between the antenna and the filter is realized; the adapter plate is directly attached to the surface of the calibration plate on the back of the antenna in a welding manner without arranging an additional joint; the connecting mode is more stable; the structure is simpler; and disassembly can be convenient.

Description

technical field [0001] The invention relates to the field of antenna connectors, in particular to a connection structure and method for connecting an antenna and a filter. Background technique [0002] With the commercialization of 5G large-scale array antennas, the research and development of 5G antennas has also attracted the attention of major communication companies. At present, 5G antenna components adopt a highly integrated and high-reliability integrated design method, which has a smaller size and reduces feeder loss to make the antenna have better performance. At the same time, the integrated design makes the whole antenna simple and reliable, greatly improving its stability during operation. [0003] In the current antenna design, compared with the traditional 4G antenna, the number of connection channels between the 5G antenna and the filter component increases geometrically. The increase in the number of channels greatly increases the manufacturing cost of 5G an...

Problems solved by technology

This connection method has the following disadvantages: 1) The overall weight of the filter is large, it takes up a lot of space, there are many joint components, and the cost is high; 2) The connection method of the quick connector needs to be assembled in three times, and the operation procedure is cumbersome and error-prone. Affect production efficiency

The disadvantages of this method are: 1) The filter will generate heat during actual operation, and the different materials to be welded have inconsistent thermal expansion coefficients, which will cause many solder joints to be made when the filter cavity and inner conductor are integrally welded on the antenna surface In order to ensure reliable connection between devices and stable antenna performance

Filters with different structures are prone to assembly errors during installation

The direct one-piece welding method makes it difficult to disassemble the incorrectly assembled filter, so the existing connection method will seriously affect the assembly efficiency of the antenna filter
