Abstract: Various embodiments of an electronic device for matching an antenna impedance may include an antenna, a wireless communication module, an impedance matching module, and at least one processor, wherein the at least one processor is configured to: select a first index corresponding to an impedance of the antenna among a plurality of sampled indexes through a first measurement in which a tuning code of the impedance matching module is configured as a reference code; identify a use environment corresponding to the first index; select a second index corresponding to the impedance of the antenna among the plurality of sampled indexes through a second measurement in which the tuning code of the impedance matching module is configured as the reference code and as a ground code corresponding to the use environment; and adjust the impedance of the antenna based on a tuning code corresponding to the second index.
