Abstract
A passive phased array imager includes a plurality of antennas, disposed on a substrate, for receiving a wavefront from a target; and a coplanar waveguide, disposed in the substrate and coupled to the plurality of antennas. Also included is a plurality of detectors, disposed across the coplanar waveguide for sampling the received wavefront, and providing multiple output voltages to an imaging circuit for displaying information contained in the received wavefront. The plurality of antennas includes at least two dipoles coupled to the coplanar waveguide, and the two dipoles are spaced by a predetermined length to provide a standing wave at a frequency of interest.
