Classification: CPC H | IPC H

Claim 20:
21. A modular radio frequency (RF) device comprising:
N base units where N is an integer greater than or equal to two, each base unit comprising a differential segmented aperture (DSA) tile including a support board and a two-dimensional (2D) array of electrically conductive tapered projections disposed on the support board with the electrically conductive tapered projections tapering in a direction extending away from the support board, wherein neighboring pairs of the electrically conductive tapered projections form RF pixels;
wherein the N DSA tiles of the N base units are arranged to form an RF aperture; and
wherein the N base units are programmed to at least one of:
operate as at least two independent subsets with each subset operating as an RF transmitter or receiver independently of the other subsets; and/or
operate coherently combine as a single phased array RF transmitter or receiver.
