A phase shifter adjusts the phase between two segments of an RF feed line that are fed with the phase shifter. Specifically, the phase shifter adjusts the phase between two signals in RF feed line segments by changing the electrical path lengths that RF energy travels down in each respective RF feed line. The phase shifter includes a coupling arm, a key, a spring, and a support architecture that fastens the phase shifter to a substantially planar surface. The support architecture is rotated manually or with a machine such as a motor. The coupling arm can include a coupling ring, a wiper element, a support trace, and a dielectric spacer. The phase shifting system is a relatively compact structure having a predetermined value of capacitance maintained between a coupling ring disposed on the coupling arm and a coupling ring disposed on a planar surface.
