摘要： 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.

摘要： The present invention relates to panel array antennas, and more particularly to a cooling system for an antenna such as a jet stream conformal panel array antenna. In one embodiment, a panel array antenna for an aircraft includes a closed-loop fluid flow path that passes through the panel array assembly and dissipates heat to the jet stream outside the aircraft. A fluid such as pressurized air passes through this closed-loop path, flowing through strategically-placed openings in the layers of the panel array assembly and flowing over and around the hot electrical components in the panel assembly. The air is heated by these electrical components, and the heated air then flows through the flow path under the top sheet, dissipating the heat to the jet stream outside. In one embodiment, a panel array antenna includes a panel assembly having a top layer through which the antenna radiates or receives a signal, and a fluid flow path through the panel assembly. A first portion of the fluid flow path is disposed below the top layer such that a fluid passing through the first portion of the fluid flow path is in heat transfer proximity to the top layer.
