Publication number: 20180054004Abstract: An embodiment of an antenna includes first and second transmission lines, first antenna elements, and second antenna elements. The first transmission line is configured to guide a first signal such that the first signal has a characteristic of a first value, and the second transmission line is configured to guide a second signal such that the second signal has the same characteristic but of a second value that is different than the first value. The first antenna elements are each disposed adjacent to the first transmission line and are each configured to radiate the first signal in response to a respective first control signal, and the second antenna elements are each disposed adjacent to the second transmission line and are each configured to radiate the second signal in response to a respective second control signal. Such an antenna can have better main-beam and side-lobe characteristics, and a better SIR, than prior antennas.Type: ApplicationFiled: August 18, 2016Publication date: February 22, 2018Inventors: Tom Driscoll, John Desmond Hunt, Nathan Ingle Landy, Milton Perque, Charles A. Renneberg, Ioannis Tzanidis, Robert Tilman Worl, Felix D. Yuen

Publication number: 20180026365Abstract: An embodiment of an antenna comprises an array of antenna elements arranged in groups of antenna elements adjustably coupled to respective reference waves. A multiplicity of patterns of antenna coupling settings are defined, each of which gives rise to a main lobe which points the antenna in a particular direction, each pattern also giving rise to respective side lobes. First and second such patterns may point the antenna in the same direction but with non-identical side lobes. In this way the clutter level from the side lobes relative to the main lobe is much smaller than would be the case if one of the patterns were employed both for transmitting and receiving. Alternatively, the first and second patterns may be used in quick succession both for transmitting, or used in quick succession both for receiving. The antenna may also switch rapidly between patterns where the main lobe points in a different direction in each pattern, allowing dithering of the beam or rapid switching between scanning and tracking.Type: ApplicationFiled: July 20, 2017Publication date: January 25, 2018Inventors: Tom Driscoll, William F. Graves, Jr., John Desmond Hunt, Nathan Ingle Landy, Christopher L. Lambrecht, Milton Perque, Robert Tilman Worl

Patent number: 8643548Abstract: A dual beam dual-selectable-polarization phased array antenna comprises an aperture unit, a printed wiring board, radiating elements, chip units, a pressure plate, and a rear housing unit. The printed wiring board has sub assemblies bonded to each other with a bonding material providing both mechanical and electrical connection. The printed wiring board is connected to the aperture unit. The radiating elements are formed on the printed wiring board. The chip units are mounted on the printed wiring board. The chip units include circuits capable of controlling radio frequency signals radiated by the radiating elements to form dual beams with independently selectable polarization. The pressure plate is connected to the aperture unit. The aperture unit is connected to the rear housing unit such that the aperture unit covers the rear housing unit.Type: GrantFiled: November 29, 2010Date of Patent: February 4, 2014Assignee: The Boeing CompanyInventors: Robert Tilman Worl, Isaac Ron Bekker, Dan R. Miller, Kenneth G. Voyce, Ming Chen, Harold J. Redd

Patent number: 8184042Abstract: A system and method for a self calibrating conformal phased array are disclosed involving a plurality of transmit/receive elements; a plurality of embedded, calibration transmit/receive elements scattered across the array; and at least one back-end processor. The calibration transmit/receive elements are used to track any physical calibration transmit/receive element's relative position change caused by array flexure. In one or more embodiments, each of the calibration transmit/receive elements transmit a tone using a small antenna, and the other calibration transmit/receive elements receive the tone using small antennas. The calibration transmit/receive elements that receive the tone measure the phase of the received tone. At least one back-end processor uses the measured phases to determine differential phases from a phase calibration table. Also, at least one back-end processor uses the differential phases to compute a change in apparent location of each transmitting calibration transmit/receive element.Type: GrantFiled: July 2, 2009Date of Patent: May 22, 2012Assignee: The Boeing CompanyInventors: Gary A. Ray, Robert Tilman Worl
