Abstract:
A low complexity/cost beamsteering antenna includes a central line feed affixed to a radial waveguide structure, radiating elements positioned along the circumference of the radial waveguide structure, and a plurality of active elements interspersed along the surface of the radial waveguide structure between the central line feed and the radiating elements. The active elements may comprise PIN diodes or microelectromechanical system (MEMS) components, and may be selectively activated/deactivated by DC switches in order to direct the propagation of an RF signal over the radial waveguide structure in a manner similar to a power divider. As a result, the RF signal may be funneled to selected radiating elements, thereby effectively directionally aiming the main lobe of the emitted radiation pattern to beamsteer the wireless transmission.
