A patch antenna includes a dielectric substrate having a body that extends a thickness from a first side to a second side that is opposite the first side. The body of the substrate includes thru openings that extend through the thickness of the body. A radiating patch is positioned on the first side of the body of the substrate. The radiating patch includes holes that are aligned with corresponding thru openings of the body of the substrate. A ground plane is positioned on the second side of the body of the substrate. At least three feed probes are electromagnetically coupled to the radiating patch such that the patch antenna is configured to generate a circularly polarized radiation pattern. Each feed probe includes a conductive path that extends within a corresponding thru opening of the body of the substrate from the second side of the body to the first side of the body. Each conductive path being exposed along the first side of the body via the holes of the radiating patch. The feed probes are positioned relative to the body of the substrate such that adjacent feed probes are spaced apart from each other along the body. The feed probes are configured to feed the radiating patch at at least three points with approximately equal power amplitude.
