Neurospectral computation for input impedance of rectangular microstrip antenna

A neural network method evaluates the integrals appearing in the spectral domain analysis of microstrip antennas. Closed form expressions are found for the integral in the indefinite form and then limits are imposed to obtain the definite integral value. This technique eliminates the difficulties of handling the singularity points encountered in the numerical evaluation of integrals. Results are compared with those of the standard spectral domain method
