Abstract

An antenna featuring a pair of radiating elements. Each pair of radiating element is fed from the same input. Each radiating element is a stacked antenna made of feeding patch and radiating patch featuring cross recessed corners. Moreover, the corners of a radiating patch and the corners of its feeding patch are cut in opposite directions. The use of recessed corner patches result in improved cross-polarization. Improved cross-polarization leads to better isolation between radiating elements of an array antenna and to an antenna featuring improved isolation from its surroundings.
