| Abstract: | A reconfigurable wire antenna is optimized by the method of moment(MoM) combined with the genetic algorithm(GA). The switches of the reconfigurable antenna are regarded as loads,and the Sherman-Morrison-Woodbury equation is used to accelerate the calculation of the impedance matrix equation in MoM.The optimized results indicate that the combination of GA and the MoM is a very effective method to optimize the reconfigurable wire antennas,and the speed of optimization is improved over 3~4 orders of magnitude. |
