摘要： An electronic device includes an antenna which transmits and receives a radio frequency (RF) signal, an RF circuit which processes the RF signal, and a control circuit which controls the RF circuit. The control circuit receives, from the RF circuit, a feedback signal, which the RF signal to be provided back as feedback from the antenna to the RF circuit, determines an impedance of the antenna based on the feedback signal, determines whether a water immersion of the electronic device occurs based on the determined impedance, and performs a set operation once it is determined that the water immersion of the electronic device occurs.

摘要： An electronic device is provided. The electronic device includes a flexible printed circuit board (FPCB) including a first conductive patch and a second conductive patch, a wireless communication circuitry electrically coupled with the first conductive patch and the second conductive patch, and a processor electrically coupled with the wireless communication circuitry. The first conductive patch is fed from the wireless communication circuitry at a first point located at a first edge of the first conductive patch or a second point located at a second edge different from the first edge, and operates as an antenna radiator which receives a radio frequency (RF) signal of a specified frequency band, the second conductive patch is fed from the wireless communication circuity at a third point of the second conductive patch, and operates as an antenna radiator which transmits or receive an RF signal of a specified frequency band.

摘要： An electronic device includes a housing, a first antenna included in a first region of the housing, a second antenna included in a second region of the housing, an antenna structure that is disposed within the housing, a coupler that obtains an impedance of each of the antennas and the antenna structure, a memory that stores a table in which the impedances of each of the antennas and the antenna structure are matched to a location or a contact of an external object, and a processor, and the processor obtains the impedances of each of the antennas and the antenna structure from the coupler when the external object approaches the electronic device, obtains the location or the contact of the external object based on the obtained impedances and the table, and transceives a signal through the antenna structure in a direction where the external object is absent.
