| Abstract: | A novel dual-mode dual-band bandpass filter using dual-mode open-loop resonator with a center-loaded T-shaped stub has been presented.There are several transmission zeros located at both sides of each passband.It provides the filter with improved selectivity and stopband suppression.Also,the centrality frequency and bandwidth of the each passbend can be controlled independently. |
