Metamaterial Loaded Wideband Patch Antenna
A new design technique for producing wideband patch antenna is introduced in this paper.The methodology involves complementary square split ring resonators and an inset fed rectangular patch antenna both designed to resonate at the same frequency.The dimensions of the complementary square split ring resonator are same as that of the split ring resonators physical dimensions,which are optimized using Artificial Neural Network.A Cascade Forward Backpropogation neural network using Levenberg Marquardt learning algorithm is utilized for optimization.The proposed neural network for optimization contains four hidden layers with variable number of neurons in each layer,which is created and trained using neural network toolbox 5.1 of MATLAB.The proposed antenna is constructed by cutting out the split ring resonator from the two corners of the patch where the feed is given to antenna.HFSS simulation of the proposed antenna shows improved bandwidth and return loss at the centre frequency of 2.4GHz.The simulation result shows remarkable improvement in antenna parameters when compared to a normal inset fed rectangular patch antenna,the only loss being a negligible decrement in the antenna gain.
