The transition-feature is characterized as a slot that extends between the arrangement of solder-balls and the ridge-air-waveguide. The transition-feature may be an L-shaped-slot or a U-shaped-slot. The assembly is designed/configured to be compatible with known printed circuit board fabrication processes.

  • Patent number: 10458073
    Abstract: Systems and methods for arresting aircraft. In specific embodiments, the systems and methods can be useful in arresting light aircraft because they typically do not have the weight to penetrate available EMAS systems. The system is generally provided as a structure having a suspended layer of energy absorbing material. A lower portion of the system can have a lower strength, used as a method to suspend an upper, stronger/more highly energy absorbent portion of the system.

  • Patent number: 10199707
    Abstract: A ball-grid-array printed-circuit-board assembly includes a die, a plurality of solder-balls, a substrate, a top-metal layer, and a bottom-metal layer. The die includes a signal-out-pad and a plurality of ground-pads arranged about the signal-out-pad.

The top-metal layer is configured to define a U-shaped-slot between a signal-portion of the top-metal layer aligned with the signal-out-pad and the substrate-integrated-waveguide, and a ground-portion of the top-metal layer aligned with the plurality of ground-pads. The U-shaped-slot is characterized by a slot-length that is selected based on the frequency of a signal, and a slot-width that is selected based on the via-height such that the signal generates an electric field directed across the U-shaped-slot whereby the signal is propagated from the signal-portion of the top-metal layer into the substrate-integrated-waveguide.
