Slot-coupled array antenna structures

摘要: Antenna structures are shown that reduce fabrication and assembly time cost, increase antenna reliability enhance performance. These include resilient flanges formed by a slotted ground plane rear which together surround feed circuit. The planes simply pressed to engage the in an overlapped resiliently interlocked relationship. In other structure, capacitance probe forms part of coaxial transition. One end face transition is configured automatically space from trunk A second available for coupling signals antenna-associated circuits (e.g., downconverter). pressed-together signal-transmission path through these with spring-loaded sockets. socket receives probe's center pin external connector. sockets can form access ports or direct antenna's exterior. structures, includes circuit converted slot-coupled patch array polymer sheet carries plurality metallic patches dielectric spacer. elements pinned pins.
