Patent number: 11139586Abstract: An antenna features a plurality of single emitters which in the x- and y-direction form an antenna array with an aperture. The single emitters are separated from each other by separating walls.

Patent number: 10295313Abstract: 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.Type: GrantFiled: May 26, 2016Date of Patent: May 21, 2019Inventor: Andrew Stan Podgorski

Patent number: 10276931Abstract: A reduced profile panel antenna is disclosed. A panel antenna configured according to an embodiment includes two opposing antenna arms disposed over a ground plane. The antenna arms include one or more corrugated or folded sections to increase the electrical path of the antenna arms within fixed physical dimensions (e.g., length and width) of the panel antenna. The panel antenna also includes passive filters to provide current loop paths of varying lengths for selected frequency ranges. Longer loop paths are employed for signals at lower frequencies (i.e., longer wavelengths) and shorter loop paths are employed for signals at higher frequencies (i.e., shorter wavelengths). The panel antenna further includes a ferrite plane disposed between the ground plane and the antenna arms to suppress radio frequency (RF) signal reflections and allow for a reduced antenna profile or thickness.Type: GrantFiled: December 13, 2017Date of Patent: April 30, 2019Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventor: Gregory J.

Patent number: 10247662Abstract: Technologies are described for providing optical analysis systems using an integrated computational element that has a surface patterned to selectively reflect or transmit different wavelengths by differing amounts across a spectrum of wavelengths. In one aspect, a measurement tool contains an optical element including a layer of material patterned so that the optical element selectively transmits or reflects, during operation of the measurement tool, light in at least a portion of a wavelength range by differing amounts, the differing amounts being related to a property of a sample. The wavelength range can include wavelengths in a range from about 0.2 ?m to about 100 ?m. Additionally, the sample can include wellbore fluids and the property of the sample is a property of the wellbore fluids.Type: GrantFiled: July 9, 2013Date of Patent: April 2, 2019Assignee: Halliburton Energy Services, Inc.Inventors: Li Gao, Michael T. Pelletier, David L. Perkins, Neal Gregory Skinner

Patent number: 10205213Abstract: 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.Type: GrantFiled: January 4, 2018Date of Patent: February 12, 2019Assignee: MTI WIRELESS EDGE, LTD.Inventor: Israel Saraf

Patent number: 10158182Abstract: A first waveguide guides a first radio wave whose electric field is vibrated in a first direction along a second direction. A second waveguide guides the first radio wave along the second direction and is cascade connected to the first waveguide. An input and output end multiplexes the first radio waves from the first and second waveguides and outputs the multiplexed radio wave, and outputs the first radio wave branched off from a radio wave from outside to the first and second waveguides. A first waveguide shift portion is shifted from the first waveguide in the first direction. A second waveguide shift portion is shifted from the second waveguide in the first direction. The vibration directions of electric fields of radio waves passing through the end parts of the first and second waveguide shift portions are rotated by 90° about a third direction.Type: GrantFiled: March 13, 2015Date of Patent: December 18, 2018Assignee: NEC CorporationInventor: Daisuke Iwanaka
