Abstract
A transmission line phase shifter includes a substrate, and first and second conductive portions adjacent the substrate with a gap therebetween. The first and second conductive portions define a signal path. A body is in the gap and includes a phase shifting material having a controllable dielectric constant for causing a phase shift of a signal through the signal path. The body has an enlarged width medial portion tapering downwards in width towards respective end portions for impedance matching with the first and second conductive portions. The width of the tapered end portions of the phase shifting material body are selected so that a separate impedance matching network is not required for impedance matching with the first and second conductive portions.
