摘要：

In this letter, a compact single-feed circularly polarized dielectric resonator antenna is proposed for X-band applications. The radiator comprises a semi-eccentric annular dielectric resonator (DR), which is a semi-elliptical DR with a hollow elliptical cylinder. A vertical coaxial probe is located adjacent to a cutting surface of the DR to excite the proposed antenna. The two main design parameters, the aspect ratio of the elliptical DR and the feeding position, were optimized, and a prototype of the antenna was fabricated and tested. The experimental results exhibit a -10-dB reflection bandwidth of 29.14% (9.41-12.62 GHz) and a 3-dB axial-ratio bandwidth of 5.71% (10.37-10.98 GHz). The measured peak gain varies from 4.17 to 4.78 dBic.
