摘要： In a stripline transmission system (fig. 1), a center conductor (12) having edges (14) is disposed between generally planar, substantially parallel ground planes (16, 18). A first dielectric (22) supports the center conductor (12) which is disposed between the first and second ground planes (16, 18). Gap portions (20) are formed adjacent the center conductor edges (14), the gap (20) containing a dielectric having a dielectric constant lower than that of the solid dielectric (22). The dielectric in the gap (20) is preferably air or vacuum. In one embodiment (fig. 2), the gap portion (42) extends in the region laterally exterior to the center conductor edges (32) and between the ground planes (34, 36). In a microstrip embodiment (50 in fig. 3), a substrate (52) has substantially parallel first and second faces (54, 56), the first face (54) bearing a center conductor (58) having edges (64) with adjacent troughs (62) formed into the first face (54), and a ground plane (60) on the second face (56). Reduced losses and improved linearity results, thereby providing applications for components such as filters, receivers and transmitters.

摘要： A tunable filter having a fixed substrate (20), first and second plates (10, 15) comprising a high temperature superconducting material is fixed on the substrate. A movable substrate (35) includes a mechanical driver (70) attached to the fixed and movable substrates. A floating plate (30) of a high temperature superconducting material is fixed to the movable substrate. The floating plate and the first and second plates are arranged to define a gap (50) therebetween, and wherein the gap is varied by length changes effected by the mechanical driver.

摘要： Thin film epitaxial high temperature superconductors are patterned to form lumped capacitors and inductors on low loss substrates. A ground plane (20), preferably of high temperature superconductive materials or high conductivity materials, such as gold or copper is placed on the substrate opposite to the patterned elements. Various structures such as a planar spiral conductor (24), or a zig-zag or serpentine conductor (42) can be formed. Additional structures such as narrow band reject filters (52) and bandpass filters can be formed. Chebyshev, elliptic and quasi-elliptic filters can be formed from a plurality of band-reject structures (116). Similarly, quasi-elliptical bandpass filters using a plurality of series connected bandpass structures with planar cross-couplings (134, 136, 138) can be formed.
