Printed monopole UWB antenna with EBG structure for Wireless Body Area Network

This paper introduces a printed monopole antenna which works in both lower and upper ultra wide-band(UWB) regions. Wireless Body Area Network (WBAN) is a rapidly advancing technology that has a variety of applications in health care and personal entertainment. IEEE Standard 802.15.6 allows us to use UWB as a promising candidate for WBAN. In this paper, mushroom-like electromagnetic band gap (EBG) stucture is used for the band notched design, and it rejects unwanted band ranging from 4.74-6.22 GHz. Antenna shows sufficient impedance bandwidth and nearly omnidirectional radiation characteristics. Specific Absorption Ratio(SAR) is also studied to know the biological effects of the antenna.
