Abstract :
In this paper, a novel ultra wideband (UWB) bandpass filter is presented using stepped-impedance resonator and vertical coupling structure. This filter configuration is presented with bandwidth up to 135.8 percent covering the 2.2-11.5 GHz range. Excellent stopband performance is obtained up to 17.7 GHz. They show the insertion loss of 1.8 dB and return loss of 14 dB at the center frequency 6.85 GHz.
