Abstract
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 has a perimeter that is defined by at least one side wall that extends along the thickness of the substrate from the first side to the second side. The body of the substrate has a dielectric constant that is greater than air. The patch antenna also includes a radiating patch positioned on the first side of the body of the substrate, a ground plane positioned on the second side of the body of the substrate, and at least three feed probes electromagnetically coupled to the radiating patch such that the patch antenna is configured to generate a circularly polarized radiation pattern. 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.
