Abstract :
The potential vector Green´s function of microstrip antenna is calculated precisely using a mixed analytical-numerical technique on personal computers (PC). Closed form expressions for both the near and far fields are used to increase the calculation speed. A family of charts showing the dependence of the closed forms validity regions on the structure parameters are obtained. The results are compared with published data enhancing the possibility of using PCs C-language programming for full wave analysis of microstrip structures. One of the main advantages of using C-language programs on PCs for Green´s functions calculation is clarified when the moment method is applied to characterize such a structure, where large matrices are always required and consequently high memory usage, which usually limits the usage of PCs FORTRAN programs.
