## Abstract A single‐fed elliptic dielectric resonator antenna is designed for circular polarization. The feed is a coaxial probe chosen with the proper parameters to achieve wideband matching and good circular polarization properties. The analysis is performed numerically using WIPL‐D. The single‐
ing-frequency bands was constructed. In this case, ⌬l is set to be 0 mm, and the dimensions of s and d are selected to be 4 and 19.5 mm, respectively. The measured and simulated (by IE3D) return losses against frequency for antenna A are shown in Figure 2. Agreement between them is satisfactory, exc
