Abstract
Disclosed is an antenna phase shifter that comprises an outer conductive trace, an inner conductive trace, a wiper arm having a pivot point, and a capacitive coupler that capacitively couples an input port to the wiper arm conductive trace and capacitively couples the input port to a phase reference port. The capacitive coupler provided DC blocking between the input port and the phase reference port, and the input port may be coupled to a Bias-T such that the DC component present at the input port may be coupled to the Bias-T to drive the phase shifter wiper arm motor. In addition, the capacitive coupler provided constant capacitance while the wiper arm rotates.
