Abstract
Fluidic self-assembly of active antenna. An embodiment that is described in the specification and drawings include a strip of substrate material having an antenna on one side, signal and power busses on the other side, and one or more channel laid out across the strip of substrate material from the antenna to the signal and power busses. The strip of substrate material may have a number of recessed regions and shaped blocks disposed in the recessed regions via a fluidic self-assembly process. The shaped blocks may include micro-switches, CMOS control circuitry, and III-V semiconductor amplifiers. The strip may then be stacked together vertically with spacers to form a two dimensional phased-array.
