1. An antenna, comprising:
a patch carrier having a plurality cavities therein, and a plurality of feed signal lines within the plurality of cavities;
a patch radiating element on said patch carrier, said patch radiating element capacitively coupled to the plurality of feed signal lines; and
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;
wherein the patch carrier comprises a substrate having the plurality of cavities within the substrate;
wherein the plurality of feed signal lines include first and second pairs of feed signal lines, which extend on sidewalls of the plurality of cavities;
wherein the patch radiating element is capacitively coupled to the first and second pairs of feed signal lines; and
wherein the first and second pairs of feed signal lines are electrically coupled to corresponding ones of the first and second pairs of feed signal output ports.
