Claim of US Patent No. 10,560,953

1. An antenna tuning method of wireless communication equipment, the antenna tuning method comprising:performing multiple sampling based on transmission signals applied to an antenna and reception signals corresponding to the transmission signals during a measurement period for which a first frequency is allocated to the transmission signals, such that a plurality of instances of sampling data are generated based on the multiple sampling, each instance of sampling data including data corresponding to the transmission signal and data corresponding to the reception signals;
calculating a parameter associated with antenna tuning based on the plurality of instances of sampling data; and
tuning the antenna based on the parameter,
wherein the transmission signals include a first transmission signal and a second transmission signal, the first transmission signal and the second transmission signal sequentially applied to the antenna during the measurement period, and
the performing of the multiple sampling includes
performing first sampling on both the first transmission signal and a first reception signal, the first reception signal corresponding to a return signal of the first transmission signal; and
performing second sampling on both the second transmission signal and a second reception signal, the second reception signal corresponding to a reflection signal of the second transmission signal.
