A 5generation (5G) or pre-5G communication system for supporting a higher data transfer rate than 4generation (4G) communication systems such as long term evolution (LTE). An apparatus for radiating a signal in a wireless communication system may include: a power amplifier; an antenna; and a combine filter unit configured to transfer an output signal of the power amplifier to the antenna. The combine filter unit may include: a first impedance matching circuit; a second impedance matching circuit; and a plurality of filters coupled in parallel between the first impedance matching circuit and the second impedance matching circuit. Allowable power of each of the plurality of filters may be lower than a maximum and/or predetermined power output of the power amplifier.

Antenna filter and electronic device comprising same in wireless communication system

The 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 transmission line structure of a wireless communication system is provided. The transmission line includes a ground area, a signal line, and a support. A first surface of the signal line is disposed to be spaced apart from the ground area via an air layer therebetween, a second surface of the signal line located opposite to the first surface may be coupled to the support, and the support may be coupled to the ground area.

Transmission line structure having a signal line spaced apart from ground by an air layer and the signal line is supported at a center part thereof

The present disclosure relates to an electronic device for radiating an output signal in a wireless communication system. In one embodiment, the electronic device includes: a power amplifier configure to receive an input signal; a splitter connected to the power amplifier, which a plurality of branches; a plurality of filters connected to the plurality of branches of the splitter; and a plurality of antenna elements connected to the plurality of filters. The plurality of antenna elements radiates the output signal that is a portion of the input signal received by the power amplifier.
