Abstract
A dual-polarized microstrip patch antenna structure comprising: a dual microstrip feed line circuitry underneath a bottom dielectric substrate; a ground plane layer overlying the bottom dielectric substrate, the ground plane layer having coupling apertures etched to the ground plane layer; a middle metallized patch layer stacked over a middle dielectric substrate; a top metallized patch layer stacked underneath a top dielectric substrate; and an air layer between the middle dielectric substrate and the top dielectric substrate separating the middle metallized patch layer and the top metallized patch layer. The microstrip feed line circuitry is configured to utilize corner-feeding techniques for enabling diagonal modes of the patch layers, and the coupling apertures of the ground plane layer are provided with a non-resonant bow-tie shape for enabling aperture coupling between the microstrip feed line circuitry and the patch layers.
