Abstract: Antenna tuning may include performing multiple sampling on a transmission signal applied to an antenna and a reception signal corresponding to the transmission signal during a period for which a first frequency is allocated to the transmission signal, such that sampling data are generated based on the multiple sampling, the sampling data including data corresponding to the transmission signal and data corresponding to the reception signal. The method may include calculating a parameter based on the sampling data, and tuning the antenna based on the parameter. A device may include a control circuit to perform the multiple sampling and set a tuning value, a radio frequency front-end to modulate the transmission signal based on the frequency and apply a return signal of the transmission signal or a reflection signal, and an antenna tuner to adjust a resonance frequency or an impedance of the antenna according to the tuning value.
