Fast and accurate analysis method of a circular patch antennas using neurospectral method

In this paper, fast and accurate analysis method is used to calculate the real and imaginary part of the resonant frequency of a circular patch antenna is presented. This method is based on artificial neural network (ANN), that is offered a very small computation time compared with other methods used to model this antenna such as Chew, Howell, Wolff, Demeryd, Nirun Kumprasert. The results of the real and imaginary part of the resonant frequency obtained by the ANN method for the circular antenna are in very good agreement with the experimental results available in the literature.
