Abstract :
A new step-impedance bandpass filter has been proposed, which has a unique dual-band feature of two tunable passbands at desired frequencies with three tunable transmission zeros as required. Simulation results have shown that the selectivity of this filter can be great improved because of the introduction of these transmission zeros
