N2 - This paper presents a Stepped-Index Rectangular Dielectric Rod Antenna (SIRDRA) with relatively high gain and wide bandwidth. The proposed device comprises of four sections with tapered permittivity, which are implemented using a single ceramic material (alumina) through unit cells. The first section consists of a solid block structure of permittivity 7.1, with the remaining three sections consisting of unit cells with dimensions precisely controlled to taper the permittivity from 7.1 at the beginning of the rod to 2.04 at its end. Simulation results show that the proposed antenna exhibits a wide matching bandwidth with a return loss below -10 dB over the entire frequency range of 15 to 22 GHz, and a peak gain of 13.1 dBi. Comparison of the SIRDRA with the solid uniform rod and the geometrically tapered rod shows that the SIRDRA exhibits better performance.
