Disclosed is a phase shifter. According to an embodiment of the present invention, provided is a phase shifter comprising: an elongated fixed board unit including one or more fixed circuit boards each having a circuit pattern formed on one surface thereof, a guiding bracket surrounding the fixed board unit and fixed to the fixed board unit, and one or more moving board units disposed between the guiding bracket and at least one surface of the fixed board unit, guided by the guiding bracket, and including one or more moving circuit boards having conductive strips formed thereon that are coupled to the circuit patterns on the fixed circuit boards.

Phase shifter including a fixed board unit and at least one moving board unit that is completely surrounded by a guiding bracket

The present disclosure in at least one embodiment provides a wireless communication device, comprising a radome comprising a first locking unit and a sealing protrusion formed along at least one side end, a lower case formed along at least one side end and including a sealing protrusion groove which is configured to receive at least part of the sealing protrusion and a second locking unit, and a fastener which is fastened to the first locking unit and the second locking unit to fix the lower case and the radome.

Phase shifter including a fixed board unit and at least one moving board unit, where a guide bracket guides the at least one moving board unit relative to the fixed board unit

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.
