Abstract
A phase shifter according to at least one embodiment of the present disclosure has a housing provided on both surfaces with respective shifting units. Each shifting unit is composed of a fixed board and a moving board. Movement of the moving board causes a phase-shifted signal to be simultaneously transferred from both surfaces of the housing to output ports. This allows more effective use of the space of the phase shifter and therearound.
