Abstract:A new improved high gain circularly-polarized antenna for millimeter-wave (MMW) applications is introduced in this paper. The proposed antenna consists of a microstrip rectangular patch radiator with corner-chopped fed by a rectangular aperture in the ground plane. To increase the antenna gain, a hollow rectangular ring dielectric resonator (DR) is installed. The DR and microstrip patch radiator together become as a single antenna element with increased gain. Extensive parametric studies are performed to addre… Show more
