Patents by Inventor Kevin M. Leong

Kevin M. Leong has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9960204
    Abstract: A method and apparatus for integrating individual III-V MMICs into a micromachined waveguide package is disclosed. MMICs are screened prior to integration, allowing only known-good die to be integrated, leading to increased yield. The method and apparatus are used to implement a micro-integrated Focal Plane Array (mFPA) technology used for sub millimeter wave (SMMW) cameras, although many other applications are possible. MMICs of different technologies may be integrated into the same micromachined package thus achieving the same level of technology integration as in multi-wafer WLP integration.
    Type: Grant
    Filed: September 22, 2016
    Date of Patent: May 1, 2018
    Assignee: Northrop Grumman Systems Corporation

  • Patent number: 7446712
    Abstract: An apparatus based on composite right-handed or left-handed (CRLH) principles to provide a transmission line or antenna structure having a plurality of cells to which one or more feed ports are attached. The apparatus is based on an equivalent circuit Right-Hand (RH) series induction (LR) and shunt capacitor (CR), and Left-Hand (LH) series capacitor (CL) and induction (LL), in which effective permittivity (e) and permeability (m) of the structure are manipulated by the choice of CR, LR, CL, and LL. One embodiment describes mushroom antenna cells (1D or 2D array) in which vias extend up from a feed network on a ground plane through at least one dielectric region to each of a first plurality of conductive elements (plates or strips). Optionally, a second plurality of conductive elements are disposed between first and second dielectric layers to form metal-insulator-metal (MIM) capacitors to lower resonance frequency.
