Abstract: A circularly polarized quadruple strip feed cylindrical dielectric resonator antenna utilizing a pair of 90° hybrid couplers is investigated experimentally. The antenna is shown to deliver an impedance bandwidth (S11 < -10 dB) of 34.5%, from 1.75 to 2.48 GHz, and an axial-ratio bandwidth (AR < 3 dB) of 25.9%, from 1.65 to 2.14 GHz. The gain and radiation patterns are found to be stable within the passband. © 2007 IEEE.
