Input Impedance of Circular Microstrip Antenna using Artificial Neural Networks

Abstract

This paper deals with the use of artificial neural networks (ANNs) for calculation of input impedance of circular patch antennas. The results obtained using ANNs are compared with the experimental findings, theoretical values and with the simulation results obtained using IE3D Package. The ANNs results are in good agreement with experimental findings.
