Abstract

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.

## Abstract A circularly polarized ceramics dielectric resonator antenna fed by a Y‐shaped microstrip is proposed and analyzed. The CP design is achieved by simply adjusting the lengths and widths of two quadrate shorted stubs. The antenna is compact in structure, whose radius is only 4.5 mm. The r
