Compact UWB Antenna With Integrated Triple Notch Bands for WBAN Applications

A triple-notch band planar ultra-wideband (UWB) antenna is proposed for wireless body area networks (WBANs) to suppress unwanted signals of conventional narrow band communication technologies. These notch bands are WiMAX (3.3-3.8 GHz), WLAN (5.1-5.825 GHz), and {X} -band downlink satellite communication systems (7.25-7.75 GHz). A complementary split ring resonator slot and two L-shaped stubs are introduced on an elliptical-shaped radiating patch to obtain UWB coverage from 2.9 to 12 GHz with three notch bands. The overall antenna structure is fabricated on FR4 substrate with a size of 12\,\,\text {mm} \times 19\,\,\text {mm} which provides a size reduction of more than 42% with respect to recent literature. The simulated and measured results indicate that the proposed antenna is a good candidate for WBAN applications.
