【Abstract】 Based on the need for the analysis of the log periodic dipole antenna (LPDA) array, an iteration method for analyzing the LPDA is presented. The method of moments (MoM) and the equivalent transmission matrix network of the antenna are properly integrated. An LPDA with thirteen elements is analyzed. The results are compared with the calculation results by using the equivalence circuit method with predicted sine distribution current along each element. The results of comparison are presented, which show that the new method is precise.更多还原
