Patent number: 10692641Abstract: A transmission line impedance transformer including at least two different dielectric media having different dielectric properties, each of the dielectric media being configured to taper in thickness along the length of the impedance transformer in an inverse relationship with respect to each other so as to form a combined dielectric medium having an effective dielectric property that is graded along the transmission path. The two or more dielectric media may be disposed between two conductors to provide an impedance transformer in which a characteristic impedance of the transmission line varies along its length in response to the gradation of the effective dielectric property of the combined dielectric medium.Type: GrantFiled: April 13, 2018Date of Patent: June 23, 2020Assignee: Raytheon CompanyInventors: Daniel B. Schlieter, Patrick J. Kocurek, Christopher A. Loehrlein, Brandon W. Pillans

Patent number: 9819068Abstract: An electronic stripline circuit includes a flexible dielectric film having a three-dimensional coiled shape that defines a spiraled inner core. At least one electrically conductive signal trace is formed on a first surface of the flexible dielectric film. The signal trace extends along a signal path to define a trace length configured to control a time delay of a coiled time delay unit.Type: GrantFiled: September 10, 2014Date of Patent: November 14, 2017Assignee: RAYTHEON COMPANYInventors: Patrick J. Kocurek, Robert S. Isom

Patent number: 8552813Abstract: Embodiments of the invention are directed toward a novel printed antenna that provides a low-loss transition into waveguide. The antenna is integrated with a heat spreader and the interconnection between the antenna and the output device (such as a power amplifier) is a simple conductive connection, such as (but not limited to), a wirebond. Integrating the antenna with the heat spreader in accordance with the concepts, circuits, and techniques described herein drastically shortens the distance from the output device to the waveguide, thus reducing losses and increasing bandwidth. The transition and technique described herein may be easily scaled for both higher and lower frequencies. Embodiments of the present apparatus also eliminate the complexity of the prior art circuit boards and transitions and enable the use of a wider range of substrates while greatly simplifying assembly.Type: GrantFiled: November 23, 2011Date of Patent: October 8, 2013Assignee: Raytheon CompanyInventors: Darin M. Gritters, Kenneth W. Brown, Andrew K. Brown, Michael A. Moore, Patrick J. Kocurek, Thomas A. Hanft
