A circularly polarised, rectangular, low-profile, dielectric-resonator antenna is presented which is fed by a 50Ω microstrip line through a single aperture. The measured 3dB axial-ratio bandwidth in the boresight direction is 14.35-14.80GHz (3%). At 14.75GHz, the input |s11| is -28dB; the measured pattern in one elevation plane decreases with increasing θ but the axial ratio is close to 3dB over 110°; in the orthogonal elevation plane, the axial ratio increases more rapidly with θ.
