1. A phase shifter, comprising:

  • a backplane carrying a transmission media trace;

    a wiper arm pivotally attached to the backplane and carrying a trace contact that is in electrical communication with the transmission media trace;

    an actuator for pivoting the wiper arm with respect to the backplane to move the trace contact along the transmission media trace while maintaining electrical communication between the trace contact and the transmission media trace;

    a signal conductor in electrical communication with the trace contact; and

    a cantilever shoe including a trace contact biasing element configured to bias the trace contact toward the transmission media trace while the trace contact moves along the transmission media trace.
