MPIE-MOM Analysis of the Horizontal LPDAArray over Ground Plane

摘要

In this paper,Mixed Potential Electric Integral Equation (MPIE) and the method of moments (MOM) are used to analyze the horizontal log-periodic dipole antenna (LPDA) array over ground plane.The microwave network theory is applied to deal with the excitation.The direct discrete complex image method (DCIM) and a quick way are applied to calculate the Sommerfeld integral in the near and far region respectively.At last,we get the direction graphs of the antenna,which is rather satisfied.
