Abstract

In this paper, a reconfigurable notched filter for ultra-wideband applications is presented. The reconfigurable notch frequencies are created to reject the interferences at these frequencies, which occur in the UWB bandpass response. The ultra-wideband bandpass filter uses multiple mode resonator, which is formed by using stepped impedance resonator. The resonators are loaded in the structure in order to reject the interferences at notch frequencies. The Cshaped resonator is reconfigured to inverted L-shaped resonator with the help of switch used in the structure and both are responsible for different notch frequencies in the different state of the switch. Two identical open stubs offer another notch frequency. The notch frequencies can be changed by controlling the length of the resonators. The switches are used in the structure to make the notches reconfigurable, which provide the flexibility to use the structure in the presence or absence of the interference.
