Analysis of half wavelength dipole antenna with the method of moments and its simulation by Matlab

Abstract:

The current distributions of the half wavelength dipole thin antenna along the wire are numerically calculated with our proposed Method of Moment(MOM)，CST-based method, and then visualized by Matlab figures. The results on the current distributions have shown that Method of Moments (Pulse-Gaussian Method of Moments) was validated by CST- based method and standing wave method (theoretical approximation method). The radiation pattern of the antenna is drawn vividly according to the current distribution calculated by three methods. The simulated result by our MOM has a time-saving advantage over that by CST-based method with the same accuracy.
