This paper presents the concept and implementation of microstrip-fed, miniaturized broadband dielectric resonator antennas (DRAs). Miniaturization and the possibility of utilizing microstrip line as a feed are achieved by the high permittivity of the resonator; wideband operation is attained by merging the resonances of two appropriate modes of DRA. The approach enforces stable radiation patterns as well as low cross polarization levels over the entire bandwidth.
