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.

Abstract: The disclosed structures and methods are directed to antenna systems configured to transmit and receive a wireless signal in and from different directions. A switchable lens antenna has excitation ports radiating radio-frequency (RF) wave into a parallel-plate waveguide structure, and a frequency selective structure (FSS). The antenna presented herein is configured to operate in two modes depending on an initial steering angle of the RF wave propagating in the parallel-plate waveguide structure. When the initial steering angle is about or less than a threshold steering angle, FSS is OFF due to its stubs being electrically disconnected from the parallel-plate waveguide structure. When the initial steering angle is higher than the threshold, FSS is ON with stubs being electrically connected to the parallel-plate waveguide structure. When ON, FSS provides phase variance to the RF wave propagating in the parallel-plate waveguide structure and increases steering angle of the RF wave.

Abstract: Embodiments are provided for an agile antenna that beamsteers radio frequency (RF) signals by selectively activating/de-activating tunable elements on radial-waveguides using direct current (DC) switches. The antenna comprises two parallel radial waveguide structures, each comprising a first radial plate, a second radial plate in parallel with the first radial plate, and conductive elements positioned vertically and distributed radially between the two plates. The radial waveguide structure further includes a plurality of quarter RF chokes which are connected to the conductive elements via respective micro-strips and tunable elements. The two parallel radial plates are separated by a height determined according to a desired transmission frequency range for RF signals, a length of the micro-strips, a diameter of the conductive elements, and a clearance space around each one of the conductive elements.
