Abstract

A dielectric resonator antennas (DRA) is good candidate to achieve a performant millimeter band antennas. They can provide larger band smaller size, but their performances when used for circular polarisation are still limited. The proposed antenna XDRA is composed of a superstrate, an aperture feed and a cross dielectric resonator. This antenna is designed to cover the ISM frequency band at 60 GHz (57 GHz-65 GHz), is shown to deliver an impedance bandwidth ( S₁₁ <;-10 dB) of 20.5%, from 56 to 68 GHz and an axial-ratio bandwidth (AR <; 3 dB) of 15%, from 58 to 63 GHz. , and a gain of 18 dB found to be stable within the passband. Results are obtained using two different electromagnetic simulators (CST Microwave Studio and Ansoft HFSS).
