Introduction: The essential development of medical science and health care systems has flagged track for the application of the UWB (Ultra Wide Band) antenna. It is combined with material science engineering to provide its service in the Body Centric Wireless Communication (BCWC). The standard operating range of the UWB antenna is from 3.1GHz to 10.6 GHz. The UWB satisfies the maximum requirement of an antenna in bio-medical and bio-apparatus manufacturing. Objective: The UWB antenna was designed to be more suitable and appropriate for WBAN (Wireless Body Area Network) ap plication with the following characteristics such as low profile, high reliability, high data rate and high efficiency. The quality of living was improved by their applications in the bio-medical productions. Methods: This proposed structure has a ground and a patch scratched over the surface of the Roger Duroid-5870 substrate with 1.6mm thickness. The structure is partially grounded with meta-material to reduce the back-body radiations. Result: The prerequisite maximum efficiency of about 98%, greater directivity, minimum SAR (Specific Absorption Rate) value and smaller size for on-body application has been achieved. Conclusion: Our proposed design yielded a UWB slot antenna with excellent characteristics making it well suitable for on-body communications.
