Abstract
An antenna includes a CPW transmission line and a radiating portion. The radiating portion is coupled to the CPW transmission line and is substantially coplanar with the CPW transmission line. The radiating portion is configured to produce a first linear polarization at a first frequency, a circular polarization at a second frequency, and a second linear polarization at a third frequency. The radiating portion includes a conductive material extending from the CPW transmission line and forming a plurality of openings in the radiating portion. The openings are asymmetric with respect to a first region of the radiating portion that is disposed on a first side of the CPW transmission line and a second region of the radiating portion that is disposed on a second side of the CPW transmission line.
