The present disclosure relates to a pre-5-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4-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.

Phase shifter including first and second boards having rails thereon and configured to be rotatable with respect to each other and an antenna formed therefrom

A phase shifter is disclosed and includes a first substrate comprising a phase change line; and a second substrate comprising an input line connected to an input port, a first output line connected to a first output port, a second output line connected to a second output port, and a connection line connecting the first output line and the second output line. The first substrate is disposed to face the second substrate and to be overlaid at a predetermined distance from the second substrate. A phase of a signal passing through a first portion of the phase change line changes by a first value according to a movement of the first substrate. The signal is branched into a first signal to be transmitted to the first output port and a second signal to be transmitted to the second output port.

Antenna apparatus including phase shifter

An RF coil has an improved structure to prevent an excessive heat from being transferred to an object, and a magnetic resonance imaging apparatus includes the same. The MRI apparatus includes an RF coil configured to receive an RF signal, wherein the RF coil may include a first cover configured to allow thermal insulation material to be injected into the inside thereof, a second cover configured to allow thermal insulation material to be injected into the inside thereof and detachably coupled to the first cover to form an inner space with the first cover, and at least one circuit board disposed in the inner space and on which a circuit element configured to receive the RF signal is mounted.
