A circularly polarized antenna exhibiting a high performance characteristic can be produced by utilizing a ground plane, a half-loop, and an electric dipole in a predetermined configuration. The circularly polarized antenna can provide benefits, such as wide axial ratio bandwidth, high gain, and simple structure, over other unidirectional circularly polarized antennas.
