  • Publication number: 20210080533
    Abstract: Single antenna direction finding is performed by physically moving a device to different device positions. As the device is physically moved, signal processing hardware within the device is used to make a plurality of signal response measurements of a signal detected by a single antenna of the device. The signal emanates from an object. The plurality of signal response measurements are made by sampling signal response at a plurality of sample times. A means for 3-dimensional positioning makes a plurality of inertial measurements at the plurality of sample times. The plurality of signal response measurements and the plurality of inertial measurements are used to produce a virtual response array vector. The virtual response array vector is used to calculate a direction of arrival from the object to the device.

  • Patent number: 10374274
    Abstract: A multifunctional electromagnetic structure is presently disclosed. Said structure is a true electromagnetic bandgap (“EBG”) material, with both surface and leaky waves suppressed from the whole structure along all lateral directions. It is also an antenna element, configured to radiate to the broadside direction. The structure has two metallization layers of concentric rings between a square-shaped radiating top metal layer and a bottom ground plane. The lower concentric ring is connected to the ground plane through a plurality of vias, while the patch of the top metal layer is fed with a probe. The EBG unit cells may be used as antenna elements in a phased array environment, where they eliminate scan blindness from the array structure along all scan directions.
