  • Multi-layer capacitive coupling in phased array antennas
    Patent number: 6822616
    Abstract: A phased array antenna (10) includes a current sheet array (20) on a substrate (23), at least one dielectric layer (24) between the current sheet array and a ground plane (30), and at least one conductive plane (25) adjacent to the substrate for providing additional coupling between adjacent dipole antenna elements of the current sheet array.
    Type: Grant

  • Printed wiring board modified gull wing signal lead connection
    Patent number: 5880657
    Abstract: The propagation of very high frequency signals, e.g., 8 to 10 GHz, via a path printed on a printed wiring board is enhanced by arranging the path so that it simulates a high-quality transmission path at very high frequencies. The path comprises a conventional lead and a series of microstrips, in which the design of the microstrips is optimized to (a) minimize insertion loss and group delay distortion, (b) maximize return loss, and (c) minimize pulse distortion.
