  • Patent number: 10333218
    Abstract: Systems, devices, and methods for determining and applying true time delay (TTD) values for compensating for free-space path length differences between a phased array and a reflector in wideband communication are disclosed. TTD values are determined for individual and groups of antenna elements in phased array fed reflector (PAFR) antennas based distances from a focal region of the reflector. The distance from the focal region of the reflector and the offset of the phased array from the reflectors focal plane can be used to determine path length differences. Corresponding TTD values for antenna elements are then determined based on the path length difference associated with the antenna elements. Each antenna element can be coupled to a TTD element to provide the corresponding TTD value to the signals received by and generated by the antenna elements of the phased array. The TTD elements include transverse electromagnetic (TEM) mode mechanisms.

  • Patent number: 10295313
    Abstract: This invention allows combining broadband GW(10+9 Watt), peak power to achieve MV/m(10+6 Volt/meter), and GV/m(10+9 Volt/meter), radiated E-fields, in the range of air or vacuum breakdown in the entire electromagnetic spectrum, including optical frequencies and beyond. Use of many antennas and independently triggered generators allows achieving GV/m field, while by preventing the E-field induced breakdown it provides control of peak power and energy content at targets. The achieved broadband MV/m E-field levels and energy density significantly exceed levels required for destruction of distant electronic targets; therefore this invention radically improves the effectiveness of the electromagnetic weapons. Furthermore, collimating multiplicity of MV/m beams allows reaching GV/m E-field that exceeds by orders of magnitude the air or vacuum breakdown needed for broadband plasma excitation at resonance plasma frequencies in the 300 GHz range.

    Abstract: An antenna array configuration is provided with h-plane splitters between ends of a feeding network and radiating elements e.g. horns, thereby to reduce the distance between the centers of the horns to less than one wavelength which results in a better side lobe level. A method of manufacturing upper and lower plates together constituting an antenna is also provided, typically making each plate in a single operation, by dividing the feeding network's waveguides at the center where there are no cross currents so as not to disturb propagation in the feeding network. The radiating elements, h-plane splitters and upper half of the feeding network may be fabricated in one plate without undercuts hence simplifying manufacture of the plate which may for example be formed using a simple molding machine or a 3 axis-CNC machine.

    Abstract: Multipoint wireless communications are coordinated in cells with radiation that is emanated from antennas in an inward direction. In an example embodiment, an apparatus includes a first antenna, a second antenna, a third antenna and a controller. The first antenna emanates radiation from a first location in an inwardly direction for a cell. The second antenna emanates radiation from a second location in an inwardly direction for the cell. The third antenna emanates radiation from a third location in an inwardly direction for the cell. The controller coordinates the emanation of the radiation via the first, second, and third antennas so as to reduce intra-cell interference for remote terminals located within the cell. The coordination may be effected in accordance with one or more coordinated multi-point (transmission/reception) (CoMP) techniques. Different numbers of sub-cells and antennas per cell and different CoMP cell organizations may be implemented.
