Reconfigurable Ultra Wide Band Notch Filter based on Complementary Metamaterial
Resonant type metamaterial approach is used to design a reconfigurable UWB (ultra wide band) notch filter based on CSSRR (complementary symmetric split ring resonator). CSSRR is etched in ground plane in the vicinity of microstrip and this combination provides UWB dual notch filter of 3.58 GHz bandwidth due to epsilon negative (ENG) behaviour of CSSRR. Truncating the symmetry of CSSRR by conductor, designed filter can be tuned to single notch at 6.64 GHz with fractional bandwidth of 34.48 % and Qfactor 44.26. Numerical calculations are performed using high frequency structure simulator and experimentally verified using vector network analyzer AV3672. Frequency responses of simulated and measured results have satisfactory agreement.
