Design and implement a 5th generation(5G)mobile millimeter wave communication beam forming module.This module is composed of an integrated antenna array radiation structure and beamforming circuit.On the basis of single-layer dual polarization microstrip patch antenna,a 7-layer stacked microstrip antenna structure is designed using stacking technology to expand band-width and to integrate with beamforming circuits.Construct a beamforming circuit using a beam-forming chip F5268 and a microstrip parallel branch Wilkinson power divider.Using finite element method software for simulation and optimization,to obtain the numerical values of various antenna parameters.Simulation results show that the impedance bandwidth of each port of the antenna rea-ches 3.90 GHz,with a relative bandwidth of 14.9％.The actual test results show that the designed module has a certain beam scanning ability,with a maximum horizontal beam scanning angle of-30° to+29°;the maximum vertical beam scanning angle is-20° to+18°.The proposed design can meet the requirements of 5G millimeter wave communication applications.
