Summary:
A circularly polarized quadruple strip feed cylindrical dielectric resonator antenna utilizing a pair of 90o hybrid couplers is investigated experimentally. The antenna is shown to deliver an impedance bandwidth (S11 < -10 dB) of 34.52%, from 1.75 to 2.48 GHz, and an axial-ratio bandwidth (AR < 3 dB) of 25.86%, from 1.65 to 2.14 GHz. The gain and radiation pattern are found to be stable within the passband.
