A Wideband Dual-Polarized Stacked Microstrip Patch Antenna with a Dumbbell Shaped Aperture

A new design for a wideband dual-polarized aperture-coupled patch antenna with dumbbell shaped coupling slots is presented. The printed antenna consists of two stacked patches and an aperture slotted ground plane which is excited using a microstrip line feed. A two-slot dual polarized antenna with a return loss bandwidth of 505 MHz is introduced using the proposed configuration. The proposed antenna is designed for 2.45 GHz and achieves stable and desirable radiation characteristics across the band.
