  • Patent number: 10734332
    Abstract: In conventional packaging strategies for mm wave applications, the size of the package is dictated by the antenna size, which is often much larger than the RFIC (radio frequency integrated circuit). Also, the operations are often limited to a single frequency which limits their utility. In addition, multiple addition build-up layers are required to provide the necessary separation between the antennas and ground layers. To address these issues, it is proposed to provide a device that includes an antenna package, an RFIC package, and an interconnect assembly between the antenna and the RFIC packages. The interconnect assembly may comprise a plurality of interconnects with high aspect ratios and configured to connect one or more antennas of the antenna package with an RFIC of the RFIC package. An air gap may be formed in between the antenna package and the RFIC package for performance improvement.
