In one example, a patch antenna includes a conductive ground plane layer 12, a conductive circular patch layer 14, a dielectric layer 30, a grounding connection 16, and a RF feed 18. The conductive circular patch layer includes a plurality of voids 20. The dielectric layer is disposed between and contacts each of the ground plane layer and the circular patch layer. The grounding connection extends from the ground plane layer through the dielectric layer and contacts the circular patch layer at a grounding location of the circular patch layer. The RF feed extends through the ground plane layer and the dielectric layer and contacts the circular patch layer at a RF feed location of the circular patch layer. The RF feed location is offset from a central axis of the circular patch layer. |
