Abstract:
A method and a closed-loop antenna impedance tuning (CL-AIT) system are provided. An input reflection coefficient is determined. The input reflection coefficient and a threshold value are compared to determine whether the input reflection coefficient is greater than the threshold value. In response to determining that the input reflection coefficient is greater than the threshold value, an optimal tuner code is determined based on a tuner code search algorithm. The optimal tuner code is applied to configure the CL-AIT system.
