  • Millimeter-wave active antenna unit, and interconnection structure between PCB boards
    Patent number: 11716812
    Abstract: A millimeter-wave active antenna unit and an interconnection structure between PCBs is provided. The interconnection structure between PCBs comprises a mainboard and an AIP antenna module. The mainboard is a first multilayer PCB on which a signal transmission line and a first pad electrically connected to the signal transmission line are provided. The AIP antenna module is a second multilayer PCB on which a second pad, an impedance matching transformation branch, an impedance line and a signal processing circuit are provided. The mainboard and the AIP antenna module are interconnected by directly welding multiple PCBs.
