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). An electronic device, in a wireless communication system, may include: a processor, an antenna array, a plurality of first radio frequency (RF) paths related to a first stream, the first RF paths each including a transmit (TX) path and a receive (RX) path, and a plurality of second RF paths related to a second stream, the second RF paths each including a TX path and an RX path, and the processor may be configured to: generate a calibration signal for the antenna array, obtain characteristic information of the antenna array based on a phase difference or a gain difference between one TX path having the first stream and one RX path having the second stream obtained for each of measurement RF paths among the plurality of the first RF paths, and calibrate the plurality of the first RF paths based on the characteristic information.

Apparatus and method for error correction in wireless communication system

A communication device for controlling a beam in a wireless communication system and a method therefor are provided. The communication device includes a lens including at least one layer in which unit cells are disposed, at least one processor configured to determine a beam pattern and control capacitance of each of the unit cells based on the beam pattern, and a transceiver for transmitting a signal in the determined beam pattern through the lens, which is capacitance-controlled. Each unit cell includes a first conductive member, a second conductive member overlapping at least a portion of the first conductive member, and spaced apart from the first conductive member, and a dielectric interposed between the overlapped portions of the first conductive member and the second conductive member. An overlap region of the first and second conductive members is arranged in a direction shielded from an external electromagnetic wave.
