Research on the application of the neural network in coupling micro-strip line design

Artificial neural network model of coupling micro-strip line is built, and used in its analysis and design. With its good precision and effectiveness, the application of neural network has the advantages of reliability, accuracy, time saving, and knowledge aid design. In this paper, with the structure size of coupling micro-strip line defined as input samples and the odd and even mode characteristic impedance and the normalized wavelength defined as output samples, a kind of coupling micro-strip line is designed by the method. The results promise a good prospect of the application.
