  • In-Band Full-Duplex Antenna With Direction Finding Capability
    Publication number: 20240014577
    Abstract: Described is an in-band full-duplex (IBFD) antenna having direction finding capability. The IBFD antenna includes a transmit antenna having an omnidirectional radiation pattern and a receive antenna configured to provide a plurality of difference beams. The IBFD antenna may be disposed on a moving platform to cover all angles around the moving platform.

  • Integrated Coaxial Notch Antenna Feed
    Publication number: 20200028242
    Abstract: A novel system for supporting a plurality of notch antenna elements is disclosed. This system allows the creation of higher power ultra-wideband step notch arrays. The system also provides electrical connection to each of the notch antenna elements via respective coaxial cables or other direct connections. These coaxial cables connect to coaxial connectors disposed on a substrate that supports the notch antenna elements. Each coaxial connector is in electrical communication with one of the notch antenna elements. By replacing the printed circuit board traditionally used, higher power can be supplied to the notch antenna elements.
