摘要

In this paper, an irregular rectangular dielectric resonator filter antenna with a nested structure is proposed, which consists of a rectangular dielectric resonator with a special structure, a metal ground plane, and a microstrip feeder. The stub-loaded slot line is etched on the ground plane to excite the dielectric resonator, and finally, two radiation nulls are generated under the combined influence of the feed structure and the special-structure dielectric resonator antenna, realizing the filtering effect. The impedance bandwidth of this antenna is about 7.6% (39.10-42.17GHz), the average gain is about 5dBi, and it is small in size and easy to integrate, and can work in the 5G millimeter wave frequency band.
