Abstract
A wideband circularly polarized hollow dielectric resonator antenna (DRA) is studied in this paper. A conducting strip is used to excite the DRA, and a parasitic patch is attached near a corner of the DRA to generate circularly polarized fields. The antenna was simulated using Ansoft HFSS. Measurements were done and the results agree well with simulations. It provides a wide 3-dB axial-ratio bandwidth of 11.8%, which is ~3 times of that of the solid CP DRA.
