Abstract :
To reduce the number of unknowns in the moment method solution for microstrip array antennas consisting of complex shaped but identical elements, the current distribution of each element is approximated by the distribution of an isolated single element. The so computed coupling shows excellent agreement with an exact calculation and leads to a tremendous decrease in computation time.
