Abstract
A patch antenna for receiving and/or transmitting circularly polarized RF signals includes a first radiating layer and a second radiating layer disposed substantially parallel to each other. Each radiating layer defines a pair of perturbation features. A ground plane layer is disposed underneath the radiating layers. The antenna also includes a feed line layer implemented as a coplanar wave guide and disposed between the radiating layers. The feed line layer allows for connection of a single transmission line to the antenna and for electromagnetically connecting the radiating layers to the transmission line. Dielectric layers separate the radiating layers, feed line layer, and ground plane layer.
