Abstract

The circularly polarized cross‐slot‐coupled hemi‐ellipsoidal dielectric resonator antenna (HEDRA) is studied in this letter. Reasonable agreement between simulation and measurement is obtained. A HEDRA is demonstrated, which has a 10‐dB impedance bandwidth (S~11~ < −10 dB) of 15.4% and a 3‐dB axial ratio bandwidth of 3.9%. The characteristics of the HEDRA are found. In addition, a comparison between the straight‐ and cross‐slot feeds is made in this letter. © 2006 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

## Abstract With the loading of a rectangular patch having a suitable aspect ratio, circular polarization (CP) radiation of low‐profile square dielectric resonator (DR) antennas can easily be obtained. The proposed antenna design can easily be excited by using a microstrip‐line feed, and many proto
