Abstract
A simple and compact filtering dielectric resonator antenna comprising: a ground plane, a dielectric substrate defined on the ground plane, a dielectric resonator defined on the dielectric substrate, and a hybrid feeding line, the hybrid feeding line comprises: a microstrip line and a metallic conformal strip, and the microstrip line comprises: a microstrip main branch, a first microstrip stub and a second microstrip stub. In the present invention, a hybrid feeding line is firstly employed to a dielectric resonator antenna. It has been shown that this hybrid feeding line can not only increase the impedance bandwidth of the passband but also can introduce two radiation nulls right near the band edges. Both good filtering and radiating performances are therefore obtained without any extra filtering circuit, giving a very compact structure.
