Two wideband single fed circularly polarized (CP) rectangular dielectric resonator antennas (DRAs) comprising square-shaped slots are proposed. Initially, two wideband linearly polarized DRAs are designed with high aspect ratio to simultaneously excite and merge two resonant modes, and . Then, CP is obtained by the technique of perturbation in the form of four and...
In this paper a novel design procedure to obtain wideband and small size dielectric antennas using high dielectric constant material is described. It is shown that by selecting the resonator shape and creating a notch on the dielectric resonator, it is possible to design rectangular dielectric resonator antenna which compact size and wide frequency coverage. Simple formulas are presented to illustrate...
