A CPW-fed rectangular dielectric resonator antenna

A CPW-fed rectangular dielectric resonator antenna is presented. The reflection coefficient and radiation patterns of such a dielectric resonator antenna with a high dielectric constant fed by an open-ended coplanar waveguide are studied. In the antenna design, the offset distance from the center of the dielectric resonator antenna to the open-ended slot center, can be used to tune the input impedance on the CPW-fed dielectric resonator antenna. Also, the calculated and experimental reflection coefficient, center frequency, antenna bandwidth, and radiation patterns are compared.
