Abstract: The analysis has been carried out on conformal circular patch antenna for MICS, ISM, WMTS applications. The proposed antenna is considered with flexible polyimide substrate material. The circular patch antenna with rectangular slits loaded has considered on top of the substrate and concentric circular ring slots has considered on the ground plane of substrate. The proposed antenna is tested in on-body and in-body characteristics of human tissue simulation model by considering the electrical properties. The proposed antenna operates at 0.41GHz (0.34 –0.52GHz), 1.24GHz (0.77–1.43 GHz) dual-bands for on-body mode with reflection coefficient of -14.2dB, -26.3dB. For in-body mode the antenna operates at 0.80GHz (0.65–0.92GHz), 1.42GHz (1.27–1.61GHz) with reflection coefficient of -21.1dB, -18.1dB respectively. Specific absorption rate (SAR), gain, radiation patterns are presented in the results.
