Abstract :
A rectangular dielectric resonator antenna (DRA) which produces circular polarisation with a single slot feed is investigated. The antenna element uses mutually orthogonal nearly degenerate modes to generate circular polarisation with a low axial ratio over a wide frequency band and a wide beamwidth
