Figure 5: Return loss of rectangular patch antenna at on body centric














                               Figure 6: Gain pattern of rectangular patch antenna

                  Later on, the parametric study about thickness each layer will be investigate. The thickness of
             each layer will increase one by one and others layer are constant. First parametric study is increase the
             layer of fat and observed the S-parameter, gain, bandwidth. The analysis is shown in Table IV.
