摘要：

A two-layer higher-order-mode circularly polarized (CP) rectangular dielectric resonator antenna (DRA) is proposed at a frequency range of 10-13 GHz using a single feed. The configuration incorporates the DRA and a dielectric coat layer with respective dielectric constants of 10 and 3.5. Utilizing the outer layer offers a number of advantages such as a wider impedance and the CP bandwidths of similar to 21% and 9.5%, respectively, as well as a high gain of similar to 11 dBic. A close agreement has been achieved between the experimental and simulated results.
