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

A The present invention relates to a phase matching band-pass filter using exponential function approximation, comprising an inductor including a parasitic resistor, a first device wherein a first amplifier is connected in a feedback mode, a capacitor including a parasitic resistor, a plurality of filter devices including a second device that is connected with a second amplifier in a feedback mode, and a coupling capacitor that connects the plurality of filter devices; the impedance of the first device has an increasing exponential function relation with a frequency, impedance of the second device has a decreasing exponential function relation with the frequency, and the first device is connected with the second device in parallel. According to the phase matching band-pass filter using exponential function approximation of this invention, conventional inductors and capacitors can be used 0 without modification or use of negative resistance, resulting in a high-performance phase matching band-pass filter. In addition, when a device with impedance characteristics that approximate an exponential function is used, the degree of frequency selection 0 becomes higher than that of conventional filters resulting in filters having high Q values and stability, such as channel selection filters.
