Abstract
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-Generation (4G) communication system such as long-term evolution (LTE). A phase shifter device according to various embodiments of the present disclosure may include: a first board configured to comprise a phase changing rail; and a second board configured to comprise an input rail connected to an input port, a first output rail connected to a first output port, a second output rail connected to a second output port, and a connection rail connecting the first output rail with the second output rail. The first board may be disposed to be spaced a predetermined distance apart from the second board so as to face and overlay the second board. The phase of a signal passing through a first section of the connection rail may vary by a first value depending on the rotation of the first board. The signal may be divided into a first signal transmitted to the first output port and a second signal transmitted to the second output port.
