Classification: CPC H | IPC H

Claim 8:
9. A radio frequency (RF) aperture comprising:
an array of electrically conductive tapered projections arranged to define a curved aperture surface defining a 360° aperture; and
RF circuitry disposed inside the curved aperture surface defining the 360° aperture and electrically connected with the electrically conductive tapered projections to receive and/or apply differential RF signals between neighboring pairs of electrically conductive tapered projections;
wherein the array of electrically conductive tapered projections includes a first array of electrically conductive tapered projections arranged to define a first curved aperture surface, and a second array of electrically conductive tapered projections arranged to define a second curved aperture surface; and
wherein the first and second curved aperture surfaces are mutually arranged to define the curved aperture surface defining the 360° aperture.
