Highly compact quad‐band bandpass filter with flexibly controllable passbands
Abstract This letter reports a highly compact microstrip quad‐band bandpass filter based on two folded λ/4 stepped impedance resonators and three folded dual‐mode short stub‐loaded resonators. The two stepped impedance resonators not only form the first passband but also serve as the feed structure...
