An adaptive technique adopting hierarchical genetic algorithms (HGA) for wideband antenna impedance tuning is presented in the paper. Three simulation examples are given for GSM, UMTS and both standards, with different types of antenna impedance. The frequency range of the dual standards is from 1.7 to 2.2GHz. Simulation results show that the proposed tuning technique can achieve good accuracy of impedance matching and load power. The reflection coefficient and VSWR obtained are also very close… CONTINUE READING
