Abstract
(EN)
Provided is a method of identifying performance of a communication circuit based on a signal transmitted and received via an antenna, capable of preventing saturation of a low noise amplifier of a receiver by ensuring isolation of a transmitter and the receiver. According to various embodiments of the present invention, an electronic device includes: at least one antenna including a patch antenna element, a first feeding unit electrically connected to the patch antenna element, and a second feeding unit electrically connected to the patch antenna element to have predetermined isolation for a signal input to the first feeding unit; a radio frequency integrated circuit (RFIC) including a first communication circuit including a first transmission circuit and a first reception circuit, which are electrically connected to the first feeding unit, and a second communication circuit including a second transmission circuit and a second reception circuit, which are electrically connected to the second feeding unit; and a processor, wherein the processor is set to output a predetermined transmission signal via the at least one antenna by using the first transmission circuit, acquire a reception signal obtained by attenuating the predetermined transmission signal according to the predetermined isolation via the at least one antenna by using the second reception circuit, and identify a state of the first transmission circuit, the second reception circuit, the RFIC, the processor, or a combination thereof based on at least a difference between the predetermined transmission signal and the reception signal. In addition, various other embodiments are possible. COPYRIGHT KIPO 2020
