Single Notch Band UWB Off-Body Wearable Antenna with Full Ground Plane

Abstract

Ultra wideband (UWB) wearable antennas with band notch property is favorable in high data rate, low power utilization and short range wireless communications without interfering on some systems. This paper proposes a planar full ground plane UWB antenna with ability to reject C band (6.3-7.15 GHz) using split ring slots. Unlike most of the planar UWB antennas that use partial ground plane to achieve wide bandwidth operation, the presence of the full ground plane makes the proposed UWB antenna appropriate for wearing applications by decreasing specific absorption rate (SAR) value. In addition, adding the split ring slots to the structure leads to the creation of a notch band and increase the antenna operating band.
