Abstract
An antenna includes a cross-polarized feed signal network configured to convert first and second radio frequency (RF) input feed signals into first and second pairs of cross-polarized feed signals at respective first and second pairs of feed signal output ports. A patch carrier is provided on the cross-polarized feed signal network. The patch carrier includes a substrate having a plurality of cavities therein, and first and second pairs of feed signal lines, which are electrically coupled to the first and second pairs of feed signal output ports and extend on sidewalls of the plurality of cavities. A patch radiating element is provided on the patch carrier. The patch radiating element is capacitively coupled to the first and second pairs of feed signal lines.
