Abstract

Methods and devices disclosed herein relate to a patch antenna. The patch antenna can include a patch having a conductive sheet including at least one edge. The patch can include a first polarization direction and a second polarization direction. A first antenna feed can be coupled to the patch. The first antenna feed can be positioned to transmit or receive a first signal along the first polarization direction. A second antenna feed can be coupled to the patch. The second antenna feed can be positioned to transmit or receive a second signal along the second polarization direction. At least one antenna aperture can be isolated from an edge of the patch and disposed along an aperture path. An orientation of the aperture path can bisect the first polarization direction and the second polarization direction. In one example, the antenna aperture can be located between the first antenna feed and the second antenna feed.
