A Planar Ultra-wideband Antenna with Dual Notched Bands Based on SCRLH Resonator
A new ultra-wideband (UWB) antenna with dual notched bands utilizing a simplified composite right/lefthanded (SCRLH) resonator is presented. By tuning the dimension of the SCRLH resonator, dual notched bands with sharp rejection can be achieved at desired frequencies to overcome interference with some already existing standards. The dual notched bands of UWB antenna at 3.5 GHz (WiMax) and 5.8 GHz (WLAN) are designed. The measurement of voltage standing wave ratio (VSWR) is in agreement with simulation. The results show that proposed antenna not only retains an ultra wide bandwidth but also owns dual bandrejections capability. The UWB antenna demonstrates omnidirectional radiation patterns across nearly whole operating bandwidth that is suitable for UWB applications.
