  • Patent number: 6992629
    Abstract: An RF signal transition includes a channelized microstrip transmission structure, and a coplanar wave guide structure in electrical communication with the channelized microstrip transmission structure. A caged troughline transition structure is in electrical communication with the coplanar wave guide structure. A caged coaxial transmission structure is in electrical communication with the troughline transition structure. The signal transition may be embedded in a flexible printed wiring board structure with a circulator for a conformal antenna structure.

  • Patent number: 6362703
    Abstract: An RF interconnect between a rectangular coaxial transmission line including a coaxial center conductor and a dielectric structure with a rectilinear cross-sectional configuration fitted around the coaxial center conductor and an RF circuit separated from the airline circuit by a separation distance. The RF interconnect includes a compressible conductor structure having an uncompressed length exceeding the separation distance, and a dielectric sleeve structure surrounding at least a portion of the uncompressed length of the compressible conductor structure. The RF interconnect structure is disposed between the rectangular coaxial transmission line and the RF circuit such that the compressible conductor is placed under compression between the substrate and the RF circuit. Examples of the RF circuit include a vertical coaxial transmission line or a grounded coplanar waveguide circuit disposed in parallel with the center conductor of the rectangular coaxial transmission line.
