Dual-frequency dual-polarized dipole antenna unit for 5G

Abstract

The invention discloses a dual-frequency dual-polarized dipole antenna unit for 5G. The dual-frequency dual-polarized dipole antenna unit comprises an antenna oscillator composed of a dielectric substrate and metal radiators, the dielectric substrate is a PCB, and the metal radiators are symmetrically arranged on the two sides of the dielectric substrate through a copper-clad process and are provided with open grooves. The radio frequency cable is connected with the metal radiators through the microstrip line and feeds the metal radiators, the shapes of the metal radiators and the open grooves can be set according to the performance and structural requirements of the antenna unit, the antenna unit has the advantages of wide bandwidth, high gain, good directional diagram consistency and convergence, and the antenna is compact in structure and small in size, has the dual-frequency dual-polarization characteristic, is good in radiation characteristic, and is especially suitable for a 5G base station with higher requirements for the bandwidth and size of the antenna.

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...
