摘要： The disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transmission rate than a 4th generation (4G) communication system, such as long term evolution (LTE). A circuit for detecting a reflection coefficient of an electronic device in a wireless communication system is provided. The circuit includes at least one processor, a plurality of analog to digital converters (ADCs), a plurality of RF elements, and a plurality of transmission lines including a first transmission line, a second transmission line, and a third transmission line, wherein the plurality of ADCs, the plurality of RF elements, and the plurality of transmission lines are correspondingly connected to each other, respectively, the plurality of ADCs are connected to the at least one processor.

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