Patent attributes
A steerable antenna assembly (“SAA”) for receiving a plurality of incident radio frequency (“RF”) signals at a plurality of incident angles is disclosure. The SAA includes an approximately spherical dielectric lens (“SDL”), a waveguide aperture block (“WAB”), a switch aperture matrix (“SAM”), and a radial aperture combiner (“RAC”). The SDL receives and focuses the plurality of incident RF signals creating a plurality of focused RF signals at a plurality of focal points approximately along the back surface of the SDL. The WAB is positioned adjacent to the back surface of the SDL and receives the plurality of focused RF signals. The SAM electronically steers a beam of a radiation pattern produced by the SAA and switch between the pluralities of focused RF signals based on electronically steering the beam. The RAC produces a received RF signal from the plurality of focused RF signals.
