Reconfigurable Triple Band-Notched Monopole UWB Antenna

This work presents a reconfigurable ultra-wideband (UWB) monopole antenna with switchable notched bands. Triple notched bands are obtained by introducing U-shaped slot, an open-ended quarter-wavelength slot and two rectangular split loop resonators. The antenna which is proposed exhibits good UWB performance, it achieves impedance bandwidth from 3.1GHz to 10.6GHz, VSWR<2, with adaptable triple band rejection to avoid interference caused by three narrow frequency bands WiMax at 3.5 GHz, WLAN at 5.5 GHz and ITU at 8.2 GHz. The antenna was designed and simulated utilizing a 0.787 mm thick ROJERS (ε
