1. A patch antenna structure, comprising:
a first conductive patch on a first layer of the patch antenna structure, wherein the first conductive patch includes:
one or more perforations at a periphery of a first side of the first conductive patch, and
one or more extended conductive portions at a second side of the first conductive patch, the second side opposite the first side;
a ground plane on a ground layer of the patch antenna structure, the ground layer spaced apart from the first layer;
a first signal feed to couple a signal to the first conductive patch; and
a second signal feed to couple another signal to the first conductive patch, wherein the first signal feed is associated with a first polarization, and wherein the second signal feed is associated with a second polarization different from the first polarization.
