High temperature superconductor staggered resonator array bandpass filter

摘要: A bandpass filter comprises multiple side-coupled strip line resonators wherein the are staggered or offset with respect to their nearest neighbors by substantially 1/4 wavelength less. In preferred embodiment, structure has parallel arrayed constant spacing between overlap Generally, amount of stagger is reduced for toward center filter. Coupling controlled varying relative resonators. The may be formed from normal metal superconducting materials, such as YBCO thallium containing superconductors. utilizing two mirror structures each comprising a substrate having ground plane and patterned resonator array on side opposite plane. another aspect this invention, tuning system utilizes variable positioning member. member moveable towards away array, resulting in tuning. threaded plug mates housing opening, permitting rotation insert.
