A polarization configurable patch antenna including a radiating layer, wherein the radiating layer has a corner truncated rectangular patch shape; and a feed capacitively coupled to the radiating layer for exciting the radiating layer, wherein the radiating layer is rotatable with respect to the feed, and the antenna is configured to generate a right-hand circularly polarized radiation field when the radiating layer is in a first rotational position and a left-hand circularly polarized radiation field when the radiating layer is in a second rotational position.
