A Novel Method to Compute Resonant Frequency of Metamaterial Based Patch Antennas Using Neural Networks
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 1
Abstract
This paper presents a novel metamaterial based miniaturised patch antenna for wireless application, whose resonant frequency is computed using an artificial neural network approach. The conventional patch resonates at 2.5 GHz; but when loaded with Complementary Split Ring Resonator (CSRR) structures; it achieves miniaturisation and is then found to resonate at 1.77 GHz. The extent, to which metamaterial creates miniaturisation, is so far not addressed analytically and is conventionally computed by a trial and error method in some commercial antenna simulators. In this paper, an attempt is made to predict the resonant frequency of the patch after it is loaded with meta-structures using neural networks for which the neural tool box in MATLAB 10 is utilized. Of all neural algorithms, the feed forward Levenberg’s back propagation algorithm based is found to provide accurate results with minimum error when trained with sufficient number of inputs. The inputs and outputs for training the network are generated from rigorous parametric analysis carried out in ANSYS HFSS® an FEM based commercial software. The analysis results are presented along with the measured performance of an experimental prototype that is found in close agreement.
