The reflector consists of a ground plane, enclosed in a ground plane frame, and a phasing plane, enclosed in a phasing plane frame. Spacers maintain the planes in connected, spaced relationship. The phasing plane includes a plurality of reactive elements sensitive to different frequencies in the bandwidth of the reflector. Thus, an E-M wave directed at the reflector is reflected to the angle of the received wave. In one embodiment, the antenna is flat and collapsible and simulates the response of a three dimensional reflector. In another embodiment, the reflector is parabolic in that an array of dipoles is suspended over a parabolic ground plane to assume a parabolic shape.
