摘要: A novel multimode bandpass filter with high and wide rejection band is proposed by using an open stub. The open-stub has two functions in the filter: (1) perturbation for operation (2) zero point generation at stopband control. With proper input/output coupling, additional poles, i.e., four can be generated structure. design then verified experiment. single structure four-mode low insertion loss, good performance, compact size linear phase.
