Dual-band 5G micro-strip antenna

Abstract

The invention relates to the technical field of antennas, in particular to a dual-band 5G micro-strip antenna. The dual-band 5G micro-strip antenna includes a dielectric substrate, the dielectric substrate includes a first surface and a second surface, metal foil is laid on the first surface of the dielectric substrate, and the first surface of the dielectric substrate serves as a grounding plane of the antenna; the first surface and the second surface of the dielectric substrate are both provided with metal patches and further include feeder ports, the feeder ports feed the metal patches through coaxial lines or micro-strip lines, the inner diameter of each coaxial line is connected to the first surface, the outer diameter of each coaxial line is connected to the second surface, the metal patches are dendritic, and each metal patch includes a plurality of polygonal radiating bodies; the antenna is small in thickness and simple in structure and can solve the communication problem of small equipment, the work efficiency is effectively improved, and compared with a traditional antenna, the antenna area is reduced.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a dual-band 5G microstrip antenna. Background technique [0002] At present, the radiation patch structure of the microstrip antenna used in mobile devices is mostly composed of a rectangular structure; the radiation patch composed of a rectangular structure has low radiation efficiency and poor directivity. [0003] The impedance matching problem is difficult to adjust, and the size is large, which is not conducive to the miniaturization development trend of related mobile devices, and at the same time increases the cost of antenna design. The 5G high-frequency band exceeds 20GHz to 100GHz, the frequency is very high, and the isolation between radiation units is poor. Contents of the invention [0004] In order to solve the problems of the prior art, the present invention aims to provide a dual-band 5G microstrip antenna. [0005] To achieve the above object, the present in...
