Abstract
A dual-polarization, circularly-polarized artificial-impedance-surface antenna has two adjacent tensor surface-wave waveguides (SWGs), a waveguide feed coupled to each of the two SWGs and a hybrid coupler having output ports, each output port of the hybrid coupler being connected to the waveguide feeds coupled to the two SWGs, the hybrid coupler, in use, combining the signals from input ports of the 90° hybrid coupler with phase shifts at its output ports.
