This paper is illustrated the small and wide band edge & inset fed circular microstrip antenna for on body communication. This work proposes an antenna consisting of a circular patch of radius 14 mm and two square slits of 5mm2 and 10mm2. The partial ground plane is used having dimensions of 28mm X 86mm in which the antenna is radiating with patch of copper foil. To describe the wearable applications, top and bottom planes of proposed antenna are separated by light weight jeans fabric of dielectric constant of 1.7 and thickness of 1mm. Further, the different antenna parameters are analyzed for the operating frequencies of 2.45 GHz, 6.47 GHz and 11.95 GHz for WiFi, WiMAX application. The results indicate that the enhanced bandwidths are achieved at these frequencies of the order of 811 MHz and 4.48 GHz for inset line feeding and 4.32 GHz and 1.19 GHz for inset feed with slot at feed point. Also this antenna has been tested on body and provided the enhanced bandwidth & good efficiency.The organization of the paper is as follows.
