Abstract
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.
