    Abstract: An electronic device according to an embodiment includes: an antenna, a filter configured to pass a signal of a specific frequency band among signals transmitted and received through the antenna, and a processor configured to control the filter to pass the signal of the specific frequency band. The filter includes: a first substrate, a second substrate facing the first substrate, a first group of electrodes disposed inside the first substrate, a second group of electrodes disposed inside the second substrate, a first transducer electrode including a first group of lines, a second transducer electrode including a second group of lines disposed to alternate with the first group of lines, and a power supply configured to apply voltages to the first group of electrodes and the second group of electrodes. The processor is configured to cause at least one of the second group of lines to be separated from the first substrate, by controlling the power supply based on a frequency of a signal to be passed through the filter.

    Abstract: The disclosure relates to a method of detecting whether an external object is in proximity to an electronic device and an electronic device supporting the same. An electronic device according to an embodiment may include: a wireless communication circuit; an antenna electrically connected to the wireless communication circuit and configured to be fed with power from the wireless communication circuit at a first point; a voltage detector including circuitry configured to detect a peak voltage applied to the antenna; and a processor electrically connected to the voltage detector and the wireless communication circuit. The processor may be configured to: determine whether an external object is within a specified proximity to the electronic device based on the peak voltage detected by the voltage detector; and control the magnitude of power applied to the antenna via the wireless communication circuit based on a determination that the external object is within the specified proximity to the electronic device.
