Engineering model for arbitrarily shaped microstrip antennas based on the collocation method

A new method for the analysis of microstrip antennas is suggested in the paper. In the method, the least-square collocation method of the method of weighted residuals (MWR) is used. The round patch antenna is analysed using the method and the results show good agreements between the calculations and experimental data. The method is conceptually simple and computationally easy. It is particularly suitable for microcomputers
