  • Patent number: 11901608
    Abstract: A chip-package-antenna integrated structure based on an SIW multi-feed network. A plurality of output terminals of the chip are connected to the SIW multi-feed network through the impedance matching network, to achieve the impedance matching between the chip and the SIW multi-feed network. The output terminal of the SIW multi-feed network is directly connected to the antenna terminals, and two or more input signals experience power combining in the substrate integrated waveguide are combined for power combining. Then the combined millimeter-wave signal is radiated by the antenna, finally realizing the power combining in the chip-package-antenna integrated structure. At the same time, the SIW multi-feed network is composed of a SIW structure, in which a plurality of via holes are arranged spaced apart to form a cavity structure.

  • Patent number: 11569191
    Abstract: A multi-feed packaged antenna based on fan-out package, which relates to packaged antennas. A first passivation layer is arranged under a packaging layer, and first and second redistribution layers are arranged on the first passivation layer to build the multi-feed packaged antenna. Connecting ends of multiple channels of a chip are connected to a feed structure of a packaged antenna. A metal layer of the feed structure is achieved by the first redistribution layer, and the second redistribution layer is mainly configured to package an antenna. The coaxial feed is adopted herein, in which two redistribution layers are provided, by which a multi-port power combining can be achieved on the antenna, providing a wide-beam performance.
