Integrated radiation unit and antenna, 5g dense antenna array

Abstract

The invention provides an integrated radiation unit, an antenna and a 5G dense antenna array. The integrated radiation unit comprises a radiation unit main body and a feeding network. The radiation unit main body comprises an insulation carrier, at least one radiation face, at least one balun and at least one feeding sheet, wherein the one radiation face, the at least one balun and the at least one feeding sheet are formed on the insulation carrier by electroplating conductive metal. Each balun is grounded. The feeding network is fixed on the radiation unit main body through the surface mounted technology. According to the invention, by use of the insulation carrier, the radiation faces, the feeding sheets and the baluns, wherein the radiation faces, the feeding sheets and the baluns are formed on the insulation carrier through electroplating of the conductive metal, so assembly processes between the radiation faces, the feeding sheets and the baluns are omitted. Through the surface mounted technology, the feeding network is fixed to the radiation unit main body and electrically connected with the feeding sheets. The integrated radiation unit is of an integrated structure. The integration modularization degree is high, processing precision is high, consistency of antenna is improved and quite big bandwidth can be achieved.

Description

technical field [0001] The invention relates to the field of communications, in particular to an integrated radiation unit and antenna, and a 5G dense antenna array. Background technique [0002] Although the 4G network is gradually built and the network scale tends to be stable, frequency resources are in short supply, huge energy consumption and network optimization issues cannot be ignored. Countries around the world focus on the research and development of 5G and develop higher frequency resources. Large-scale dense array is the core technology of future 5G research and development, and the radiation unit is the core component of 5G antenna. [0003] At present, the radiation unit is generally in the form of a split body, that is, the feed sheet, the radiation surface and the balun need to be assembled and welded many times to form a complete radiation unit. In this process, there are welding between the top of the feed sheet and the radiating surface, and welding betw...
