## Abstract A stub‐loaded stepped‐impedance resonator (SIR) filter with an ultra‐wide upper stopband is proposed. For a 20‐dB rejection level, by properly choosing the number and lengths of the stubs, the second, third, and fourth resonances of the SIR filter are pushed to left and the seventh reso

## Abstract In this letter, we proposed the design of novel dual‐band bandpass filter (BPF) with a broad upper rejection band using only two asymmetric stepped impedance resonators (SIRs), which has a smaller circuit size in comparison of previous works. The feature of the asymmetric SIR is only on
## Abstract An ultra‐wideband microstrip filter with good out‐of‐band performance is designed and demonstrated. The filter design is based on a circuit model for an optimum short‐circuited stub transmission‐line filter whose unit elements or connecting lines are nonredundant. Substituting the conne
## Abstract This article presents a novel ultra‐wide bandpass filter on microstrip line with sharpened roll‐off skirts, extended upper‐stopband, and controllable notch‐band. A shunt stub structure with two split symmetrical open end stubs is purposed, aiming to create a pair of transmission zeros a
## Abstract A novel ultra‐wide band bandpass filter with notched band is presented.Multi‐mode resonator is realized using a stepped‐impedance slotline. The resonator is orthogonally coupled to the microstrip feed lines, and ultra‐wide passband is obtained. Microstrip open loop resonators are loaded
