1. A circularly polarized array antenna comprising:
a ground plane; and
a plurality of circularly polarized antennas, each of the circularly polarized antennas configured to communicate over a frequency band ranging from 24 GHz to 52 GHz, each of the circularly polarized antennas comprising:
a column substrate coupled to the ground plane such that the column substrate is positioned closer to a center of the ground plane than a periphery of the ground plane, the column substrate having a plurality of faces; and
a plurality of isolated magnetic dipole elements, each of the isolated magnetic dipole elements disposed on a different face of the plurality of faces of the column substrate.
