Design of a microstrip‐line‐feed slot‐coupled cylindrical dielectric resonator antenna (DRA) for circular polarization (CP) is investigated experimentally. The occurrence of the two orthogonal near‐degenerate resonant modes is mainly excited by a perturbed annular slot that is, a C‐shaped slot. The CP resonant frequency can be adjusted by using different slot sizes. Experimental results of the proposed C‐slot coupled DRA are presented and discussed. © 2002 Wiley Periodicals, Inc.
