Abstract :
A new method to improve the directive gain of patch antenna array for ISM band of 2.4 G Hz with metamaterial is presented. This method is based on suppressing the electromagnetic interference between the elements of antenna array. The electromagnetic interference between elements of antenna array is reduced by using Split Ring resonator metamaterial. Here Split ring resonator metamaterial acts as a notch filter between the arrays elements thereby reducing the mutual coupling between the array elements. Suppressing of mutual coupling between the array elements allows for denser packing and enhanced directivity of antenna array. The electromagnetic characteristics of SRR metamaterial and patch antenna array with and without SRR mtamaterial are studied. Simulation results show that by introduction of SRR metamaterial into patch antenna array there is improvement of directive gain of patch antenna array thereby approaching a superdirective patch antenna array.
