A compact, wideband and high gain anisotropic rectangular dielectric resonator antenna is reported. This antenna consists of a multilayer dielectric structure which emulates uniaxial anisotropy and a relatively tall feed probe that acts both as a perfect electric conductor symmetry plane and the excitation of the higher order radiating mode. The multilayer structure and the tall feed probe are responsible...
Application of the grooved substrate is presented for the design of an unequal Wilkinson power divider. The grooves are applied along one of its strips which requires high characteristic impedance for the purpose of overcoming its conventional narrow width. The grooves are oriented parallel to the strip and just next to it. The groove depths are selected such that, for a suitable width of the strip,...
