Document Type and Number:
WIPO Patent Application WO/2023/282665
Kind Code:
A1
Abstract:
The present invention relates to a phase shifter and a communication device comprising same. In particular, the phase shifter comprises: a base panel; a fixed substrate which is laminated and fixed on one side or the other side on the base panel and has a plurality of circuit patterns printed on the top surface; and a phase shift switching unit including plurality of movable substrates which include movable strip terminals respectively contacting the the circuit patterns of the fixed substrate, wherein the positions of contact of the plurality of movable substrates with respect to the circuit patterns are changed by moving the moveable substrates moved back and forth by a prescribed distance in the horizontal direction on the base panel. The phase shift switching unit provides the advantage of maximizing space utilization by moving the plurality of movable substrates toward the circuit patterns while elastically supporting same.
