Abstract

See full text

Disclosed is an integrated structure of a differential dielectric resonator antenna and a separately controllable dual-band filter. The integrated structure includes a dielectric substrate, a rectangular dielectric resonator and a feed structure. Two functions, i.e., an antenna function and a filter function, which do not interfere with each other, are realized at the same time. Differential excitation is performed on a main mode of the rectangular dielectric resonator, so as to design a differential dielectric resonator antenna. A separately controllable first passband of the filter is integrated and realized on a virtual ground of the differential dielectric resonator antenna, and then a separately controllable second passband of the filter is realized by using a reflection ground. The antenna and the filter share the same module, but maintain good isolation, such that the number and volume of microwave devices in a radio frequency system can be reduced.
