Apparatus and Assembling Method of a Dual Polarized Agile Cylindrical Antenna Array with Reconfigurable Radial Waveguides

摘要

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.
