Abstract

The invention relates to the technical field of antennas, in particular to an ultra-wideband microstrip antenna. It includes a substrate on which a radiation patch is arranged; the radiation patch includes a radiator; the radiator includes a first part and a second part connected to each other; the first part and the second part are ring structures , and the first part is provided with a first opening, and the second part is provided with a second opening. By adopting the above-mentioned structure, the present invention has the advantages of ultra-wideband, high gain, miniaturization and good omnidirectionality. The effective working frequency band of the invention is 2.98-22.26GHz, the total bandwidth is 19.28GHz, the average gain is greater than 4dBi, the size is 23mm x 34mm, and the omnidirectional radiation characteristic is achieved at 3.1GHz-6GHz.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to an ultra-wideband microstrip antenna. Background technique [0002] The microstrip antenna is on a thin dielectric substrate, one side is attached with a thin metal layer as a ground plane, and the other side is made of a metal patch of a certain shape by photolithography and etching, and the patch is fed by a microstrip line or a coaxial probe composed of antennas. Microstrip antennas include microstrip vibrator antennas in the form of slender strips, and also in the form of area units. The area unit can be equivalent to a resonant cavity, and good radiation characteristics can be obtained near its resonant frequency, that is, in the working frequency band. Although the research and application of microstrip antennas are very mature, there are still many problems worth studying in the analysis and research of the electromagnetic scattering characteristics of microstrip antenna...
