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

A filter in a wireless communication system includes: a cover; a housing; a printed circuit board (PCB); a resonance plate provided between the cover and the PCB; and a plurality of resonators provided on a single layer in the resonance plate.

Antenna filter and electronic device including same in wireless communication system

The disclosure relates to a 5generation (5G) or pre-5G communication system for supporting a higher data transfer rate than a 4generation (4G) communication system, such as long-term evolution (LTE). An antenna module is provided. The antenna module includes a filter for filtering a radio frequency (RF) signal, and a sub printed circuit board (PCB), the sub-PCB comprises a passive circuit for processing the RF signal, and, the sub-PCB may be coupled to the filter such that the filter operates as a bumper when being coupled to a filter board.

The disclosure relates to a 5generation (5G) or pre-5G communication system for supporting a data transmission rate higher than 4generation (4G) communication systems such as long term evolution (LTE). A radio frequency (RF) filter in a wireless communication system is provided. The RF filter includes a structure including a resonance unit, and a cover plate at which a tuning structure is formed. The tuning structure includes a flexible arrangement with respect to the cover plate through an opening in the cover plate.

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.
