Inducti¨ely and capaciti¨ely end-coupled quarter-wa¨elength-resonator bandpass CPW filters are introduced. For a gi¨en bandwidth and passband shape, the new filters ha¨e a smaller size, wider upper stop band and looser coupling between resonators than end-coupled half-wa¨elength-resonator CPW filter

## Abstract In this letter, a compact dual‐band microstrip bandpass filter (BPF) with independently controlled center frequencies is designed using meander short‐circuit quarter‐wavelength resonators. Its coupling scheme and equivalent circuit model are analyzed. A good agreement between simulation
