Abstract

The antenna tuning may include performing a plurality of samplings on the transmission signal and a reception signal corresponding to the transmission signal during a period in which the first frequency is allocated to the transmission signal applied to the antenna, so that sampling data is generated based on the plurality of samples, the The sampled data includes data corresponding to the transmitted signal and data corresponding to the received signal. The method may include calculating parameters based on the sampled data, and tuning the antenna based on the parameters. A device may include: a control circuit that performs multiple sampling and sets a tuning value; a radio frequency front end that modulates a transmitted signal based on frequency and applies a return or reflected signal from the transmitted signal; and an antenna tuner that adjusts according to the tuning value The resonant frequency or impedance of the antenna.
