Integrated antenna assembly and antenna array

Abstract

The invention relates to the technical field of base station antenna manufacturing, and provides an integrated antenna assembly and an antenna array, and the integrated antenna assembly comprises a feed network module and an antenna unit radiation fin. The feed network module comprises a bracket, a feed network elastic sheet and a reflecting plate elastic piece; the two sides of the reflecting plate elastic piece are provided with separating walls perpendicular to the reflecting plate elastic piece. A groove with the same shape as the feed network elastic sheet is formed in one surface of the bracket, the feed network elastic sheet is arranged in the groove in an attached mode, and the depth of the groove is larger than the thickness of the feed network elastic sheet; the reflecting plate elastic piece is arranged on the other surface of the bracket; the feed network elastic sheet, the reflecting plate elastic piece and the bracket are integrally formed through injection molding. The integrated antenna assembly provided by the embodiment of the invention is few in required parts, simple in structure, convenient to assemble, free of welding, easy to automation, low in production cost and suitable for large-scale efficient production.

Description

technical field [0001] The present application relates to the technical field of base station antenna manufacturing, in particular to an integrated antenna component and an antenna array. Background technique [0002] With the advent of the 5G era, 4G antennas are gradually transitioning to 5G antennas. Among them, Massive MIMO (Multiple Input Multiple Output) array antenna technology is one of the key technologies for upgrading 4G antennas to 5G antennas. In 4G antennas, the MIMO antenna form Generally, 2T2R or 8T8R is the main type. After 5G is upgraded to Massive MIMO technology, the antennas will be arranged in the form of large-scale array antennas. At present, 64T64R or 32T32R are mainly used, which leads to a substantial increase in the demand for antenna components. [0003] At present, the 5G Massive MIMO antenna usually adopts the following two structural schemes.

Problems solved by technology

[0003] At present, the 5G Massive MIMO antenna usually adopts the following two structural schemes. The first is that the PCB vibrator or sheet metal stamped vibrator is welded on the feed network board made of high-frequency PCB. The antenna components made by this welding method, because each vibrator There are many solder joints, which leads to unstable consistency of each port after the formation of the array. At the same time, the welding process takes a long time, resulting in low production efficiency of the antenna components; the second is to perform selective electroplating or laser direct on the plastic injection molding structure. Forming technology to obtain an antenna solution with an integrated vibrator and feed network. However, this type of antenna line requires a large amount of laser engraving or electroplating. The process is difficult, the yield rate is uneven, and the equipment cost is large.
