Implementation of adaptive multiscale moment method in analyzing a wide band E-shaped patch antenna for wireless communications

In this paper we employ adaptive multiscale moment method (AMMM) for the analyzing a wide band E-shaped patch antenna. This algorithm employs the conventional moment method and a special matrix transformation. The compression is applied directly to the solution then the size of the linear equations to be solved is reduced, thereby improving the efficiency of the conventional moment method. We were interested to implement this method in a 30.3% bandwidth E-shaped patch antenna, resonating at wireless communication frequencies of 1.9 and 2.4 GHz. The basic difference between this methodology and the other techniques presented so far is that we apply the compression not to the impedance matrix, but to the solution itself directly using an iterative solution methodology
