Abstract

The present disclosure relates to a communication technique and a system for integrating a 5G communication system with IoT technology to support higher data transmission rates than those of 4G systems. The present disclosure can be applied to intelligent services (e.g., smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail, security and safety-related services, etc.) based on 5G communication technology and IoT-related technology. An electronic device according to various embodiments comprises: a sensor module; an antenna module electrically connected to the sensor module; and a processor. The sensor module measures a distance from the antenna module to a user. The processor determines a frequency band capable of transmitting a transmission signal at maximum output based on the distance. The antenna module outputs the transmission signal at maximum output through the determined frequency band.
