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...
