Abstract :
A novel dual-band bandpass filter realized by open-loop resonators with series cascade of shorted-circuited stubs and open-circuited stubs is presented. By using the series cascade of stubs, a dual-band band pass filter with good performance is realized. The center frequencies of the filter are at 1.70GHz and 4.90GHz. Electromagnetic simulations show the filter with a good frequency response.
