Abstract
A phase shifter includes a transmission line and a plurality of varactor diodes connected in parallel to the transmission line. The varactor diodes have a high enough density that they uniformly load the transmission line. By controlling the reverse biasing of the varactor diodes, the phase shift produced by the phase shifter can be controlled.
