Circular Polarized Antennas Including Static Element

摘要

An apparatus comprising at least one antenna for transmission and/or reception of circularly polarized electromagnetic radiation. The antenna includes a radiating element, a static element, and a single feed line. The single feed line is coupled between the radiating element and a circuit that drives the antenna. The radiating element has a non-symmetrical outer perimeter shape. The radiating element may include an aperture. The antenna may further include a ground element and a supplemental ground feed structure, the supplemental ground feed structure located between the radiating element and the ground element and the radiating element located between the supplemental ground feed structure and the static element.
