A wideband high gain circularly polarized layered cylindrical dielectric resonator antenna (DRA) that operates in a higher order mode is proposed in the X-band frequency range. The antenna consists of two dielectric layers having different dielectric constants and radii. The results demonstrate a considerably improved performance as a result of adding the outer dielectric layer, where wider impedance and axial ratio bandwidths have been attained in conjunction with a higher broadside gain of ~ 14 dBic. A prototype has been built and measured with close agreement between experimental and simulated results.
