Figure 8: Parametric study thickness of skin rectangular patch antenna
(a) Thickness of skin, (b) Return loss and (c) Gain

From parametric study thickness of muscle in Table VI, it is show the changing thickness of
muscle can effected return loss and gain in small percent. They have slightly increased and decreased
when the thickness of muscle become higher. But it is not effected the bandwidth value since the
bandwidth is still show 0.06 Hz. Figure 9 below shows the result of analysis thickness of muscle
increased to 8 mm.
