Neural CAD for fractal multiband antenna

In the present paper a circular loop antenna based on Koch fractal geometry is designed for the multiband frequency response in the frequency range of 2-45 GHz. This band is well known for the many wireless communication band, satellite communication and microwave communication. A CAD tool based on artificial neural network (ANN) is developed for the analysis and synthesis of Koch loop fractal antenna for the multiband applications. A developed CAD ANN tool that avoids the repeated use of the simulator for the analysis and synthesis for Koch loop fractal antenna. This neural CAD is developed by the training of neural network model for Koch loop fractal antenna. The performance of the neural CAD is tested with the CST software.
