Description

technical field [0001] The invention belongs to the technical field of antenna equipment, and in particular relates to a dual-frequency dual-polarization dipole antenna unit for 5G. Background technique [0002] The large-scale application of 5G technology has led to explosive growth in the demand for 5G antennas. Due to the limited working bandwidth of dipole antennas, dipole antennas used as 5G antennas mostly use large-scale antenna arrays to achieve beamforming technology and With MIMO technology, 5G antenna arrays often require multiple antenna units to meet broadband performance requirements, and 64 units, 128 units or more units are used to increase the communication rate. The increase in the size of the antenna array also greatly increases the volume, weight and weight of the array antenna. The cost cannot meet the requirements of small structure size and sufficient bandwidth at the same time. Contents of the invention [0003] Purpose of the invention: The purpos...
