An antenna system includes a ground plane including a first corner and a second corner that are positioned along a first common edge. A first antenna element is disposed at the first corner of the ground plane and includes a first slot. A second antenna element is disposed at the second corner of the ground plane and includes a second slot. The first antenna element and the second antenna element are fed with an electromagnetic signal and the electromagnetic signal at the first antenna element is approximately 90 degrees shifted from the signal at the second antenna element. The first antenna element and the second antenna element form an antenna structure, and the antenna structure transmits circularly polarized radiation.
