Simul<strong>at</strong>ion result of Return loss and bandwidth ofRectangular <strong>microstrip</strong> p<strong>at</strong>ch <strong>antenna</strong> loaded withmetam<strong>at</strong>erial structure is shown in Fig 11.The proposed metam<strong>at</strong>erial structure reduces the return lossby -8.107dB and increases the bandwidth up to 17.96 MHz.Intern<strong>at</strong>ional Journal of Advanced Technology & Engineering Research (IJATER)Figure13.

Simul<strong>at</strong>ion of Return loss and impedance bandwidthof RMPA with proposed metem<strong>at</strong>erial structure <strong>at</strong> oper<strong>at</strong>ingfrequency <strong>1.881</strong> GHz.The Simul<strong>at</strong>ed result of RMPA <strong>using</strong> <strong>split</strong> <strong>rectangular</strong> shapeis reduced return loss of -18.175 dB and Bandwidth of 22.5MHz.It is clear th<strong>at</strong> the Directivity of proposed <strong>antenna</strong> is almostunaffected in comparison to simple RMPA alone.Figure14.
