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 address the effect of varying the antenna parameters on the operational frequency bandwidth. For further gain enhancement, a hemi-spherical dielectric lens made of high-dielectric constant is installed above the proposed antenna. Simulated results using Computer System Technology Microwave Studio (CST MWS) software programs based on finite integral numerical modeling technique (FIT) have been presented. The proposed novel antenna is considered a good candidate for circularly-polarized and high gain MMW applications for microwave detection and imaging applications.
