The invention relates to an antenna module and a 5G antenna. The antenna module comprises an insulating substrate, two antenna subarrays, a phase shifter, a power divider and an antenna input interface. Each antenna subarray comprises more than one radiation unit. The two antenna subarrays are arranged on one surface of the insulating substrate. The phase shifter is arranged on the other surface of the insulating substrate. The phase shifter comprises a cavity. The cavity and the insulating substrate are of an integrated structure. After a signal is input from the antenna input interface, onepath of signal is electrically connected with one antenna subarray through a first power dividing line, and the other path of signal is electrically connected with the other antenna subarray through the phase shifter and a second power dividing line. Under the phase shifting effect of the phase shifter, the two antenna subarrays form a phase difference, and the effect of adjusting the downward inclination angle is achieved. The cavity of the phase shifter and the insulating substrate are of an integrated structure, so that independent manufacturing is not needed, connecting pieces are not needed for assembly and combination, and simple assembly, automatic production, cost reduction, low profile and light weight can be realized.
Description
technical field [0001] The invention relates to the technical field of communication antennas, in particular to an antenna module and a 5G antenna. Background technique [0002] As mobile communication technology enters the 5G era, higher requirements are put forward for the miniaturization and weight reduction of the complete antenna. The phase shifter, reflector, power dividing network and radiation unit of the 5G antenna in the traditional technology are usually designed separately, and are assembled together by splicing and connecting parts such as screws and rivets. In this way, traditional 5G antennas have the problems of complex assembly, low degree of automation, high cost, and heavy weight. Contents of the invention [0003] Based on this, it is necessary to overcome the defects of the prior art and provide an antenna module and a 5G antenna, which can realize simple assembly, automatic production, cost reduction, and light weight. [0004] The technical solutio...
