In this communication, a novel synthesis design method is proposed for designing a wideband filtering dielectric resonator antenna (FDRA) using multimode resonators (MMRs). To start with, the proposed FDRA composed of a tri-mode stub-loaded resonator as the feeding network and a rectangular dual-mode dielectric resonator (DR) as the radiator is introduced. Then, an exact synthesis and design procedure is proposed for facilitating to design this FDRA. Following that, an appropriate coupling topology is selected to allocate a composite quintuple-mode resonator to achieve a wideband operation for this FDRA. Finally, for an experimental verification, a prototype of the FDRA is designed, fabricated, and measured. The simulation and measurement results are in well accordance with each other, showing a good filtering performance from 2.2 to 3.1 GHz, an average gain of 9.1 dBi, and good out-of-band suppression. read more
