Abstract
A phased array antenna includes a plurality of antenna elements and a phase shifting device connected to the plurality of antenna elements. The phase shifting device includes a substrate, and a plurality of phase shifters on the substrate. Each phase shifter includes a first conductive portion adjacent the substrate and defining a signal path, and a body adjacent the first conductive portion and comprising a phase shifting material having a controllable dielectric constant for causing a phase shift of a signal being conducted through the signal path. The bodies are laterally spaced apart from one another, and may have a thickness equal to or greater than about 0.002 inches. In forming the phased array antenna, each body is bonded to respective signal paths using production surface mount or similar machines.
