Sextuple-mode ultra-wideband bandpass filter with wide upper stopband
A sextuple-mode ultra-wideband bandpass filter with wide upper stopband is presented in this paper. The wide upper stopband is achieved by attaching two open-circuited stubs 90° from the feed lines inside a ring resonator. These stubs introduce two transmission zeroes above the UWB passband to enhance the upper stopband. Analytical design of the six transmission poles and two transmission zeroes is described. The filter is then fabricated on RT/Duroid 6010.2LM substrate and measured. The simulated and measured responses are in good agreement showing upper stopband greater than 20dB up to 28GHz.
