1. A 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; and
at least one RF unit (RFU) having RF connections with the DSA tile to transmit and/or receive RF signals via the RF pixels of the DSA tile;
wherein the at least one RFU of the base unit is programmed to operate the base unit in a plurality of different RF transmit and/or receive modes including at least one independent mode in which the base unit operates as an RF transmitter or receiver independently of any other base unit and at least one cooperative mode in which the base unit coherently combines with at least one other base unit as a single phased array RF transmitter or receiver.
