A Quadruple Band-Notched UWB Antenna by Using Arc-Shaped Slot and Rotated E-shaped Resonator.

A simple quadruple band-notched ultra-wideband (UWB) antenna is proposed and its performance is investigated both numerically and experimentally. The proposed quadruple band-notched UWB antenna is realized based on an asymmetric planar monopole antenna which consists of a fan-shaped radiation patch, a microstrip feeding line and a trapezoidal ground plane. By etching an arc-shaped slot with a gap and adding a rotated E-shaped resonator beside the microstrip feeding line, four notched bands are achieved to suppress potential interferences from WiMAX (3.3-3.6 GHz), WLAN (5.15-5.35 GHz, 5.725-5.825 GHz) and uplink of X-band satellite communication system (7.9-8.4 GHz). The proposed monopole antenna can operate over 2.94-12 GHz band with VSWR<2 except these notch bands. Simulation and measurement results of the fabricated prototype demonstrate that the proposed antenna has quadruple band-notched characteristics and nearomnidirectional radiation patterns, making it suitable for UWB communication applications.
