Abstract :
New method of simulated annealing algorithms combined with MOM used for calculation of LPDA´ phase center is presented in this paper. By this method, The characteristic of phase center varies with frequency is analyzed and the fluctuated curves of phase are presented within the main lobe in E-plane and H-plane radiation patterns. It can be concluded from the good result of phase center that this method is an effective method to calculate the LPDA´ phase center
