Summary
As conclusion, rectangular patch antenna shows the best shape of the compact structured antenna in
free space communication than circular patch antenna. According Table VII, Rectangular shape is
obtained the higher minimum of return loss at -28.087 dB compared to circular shape at -10.054 dB.
From the simulation result, rectangular shape obtained the good bandwidth from 0.0603 Hz than
circular shape which is shows 0.0212 Hz. From the analysis we can conclude that rectangular is the
best shape from circular because the advantages of save costing to fabricate, very thin and can be
design in the smaller size. Rectangular shape is suitable for practical wireless communication
applications and successfully in designing [1][2].

In On-Body Centric Communication, the result obtained rectangular shape provide the good
result of man and woman which given the higher gain at when the thickness of skin is increased.
According to (Peter S Hall et al.) the dielectric material of human tissue proved the characteristics of
skin dept is very small and low transmission power. Compare to fat layer, there is no effect to gain,
return loss and bandwidth. This happens because of the characteristics of fat relatively small volumes
[5][6].
