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 agile antenna device comprises a first radial waveguide structure encased in a first frame, a first line feed connected to the first waveguide structure, a second encased radial waveguide structure similar and coupled to the first waveguide structure. The two waveguide structures include the tunable elements controlled by the DC switches. A second line feed is connected to the second waveguide structure. The two line feeds provide the RF signal to the antenna. The antenna device also includes a plurality of radiating elements positioned between the first radial waveguide structure and the second radial waveguide structure, and distributed radially around a circumference of the first radial waveguide structure and a circumference of the second radial waveguide structure.

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.
