Abstract
AbstractA low‐profile rectangular dielectric resonator antenna (RDRA) through the slot‐based feed method is studied for the multiband operation. Based on the perfect magnetic wall (PMW) model and dielectric waveguide model (DWM), field distributions and resonant frequencies of the RDRA intrinsic modes are calculated for multimodal analysis. The microstrip backed slot coupling scheme is employed for the simultaneous excitation of multiple modes. A prototype is fabricated and validated. By generating 10 modes simultaneously including TEy111 to TEy711, and TEx221 to TEx421 modes. The RDRA is able to provide good multiband performance.
