Abstract
Theoretical and experimental results for a circularly polarised (CP), rectangular, low-profile, dielectric-resonator (DR) antenna are presented. The DR is fed by a 50Ω microstrip line through a single aperture. The measured 3dB axial-ratio bandwidth in the boresight direction is 14.35-14.80 GHz (3%). At 14.75 GHz, the measured input reflection coefficient is -28 dB; the measured axial ratio in one elevation plane is close to 3 dB over 110° but it increases more rapidly with the elevation angle in the orthogonal elevation plane. Theoretical patterns compare fairly well with the measurements.
