Patent number: 11081773Abstract: An apparatus includes a signal splitter configured to receive an input signal for transmission and to split the input signal to form two or more sub-signals. The apparatus further includes a first amplifier configured to generate a first amplified sub-signal, a second amplifier configured to generate a second amplified sub-signal, a first launcher coupled to the first amplifier and to a waveguide, and a second launcher coupled to the second amplifier and to the waveguide. The first and second launchers are coupled to the waveguide such that a first radiative signal generated by the first launcher responsive to the first amplified sub-signal and a second radiative signal generated by the second launcher responsive to the second amplified sub-signal are combined in the waveguide to form a transmission signal corresponding to the input signal.Type: GrantFiled: July 10, 2019Date of Patent: August 3, 2021Assignee: THE BOEING COMPANYInventors: John E. Baldauf, James M. Barker, Enrique M. Alvelo, William J. Ceely

Patent number: 10985468Abstract: An apparatus includes a first conductive patch coupled to a first surface of a dielectric layer, a second conductive patch coupled to a second surface of the dielectric layer, and a probe coupled to the second conductive patch. The apparatus further includes a waveguide having a wall conductively coupled to the first conductive patch. Responsive to a signal provided to the second conductive patch by the probe, interaction of the waveguide, the first conductive patch, and the second conductive patch generates a transmission signal that propagates in the waveguide.Type: GrantFiled: July 10, 2019Date of Patent: April 20, 2021Assignee: THE BOEING COMPANYInventors: John E. Baldauf, James M. Barker, Enrique M. Alvelo, William J. Ceely

Patent number: 8040288Abstract: Systems and methods for providing an antenna enabling hemispherical coverage are disclosed. The system includes a conductive enclosure having an open portion and a closed portion. The system further includes a pair of perpendicularly-disposed dipole antennas. Each antenna of the perpendicularly-disposed dipole antennas includes a pair of conductors extending to a pair of tips disposed outside of the open portion of the conductive enclosure. The system further includes a hybrid coupler having a pair of output terminals coupled to each pair of conductors of each antenna of the perpendicularly-disposed dipole antennas. The hybrid coupler is configured to apply signals of equal magnitude to the each antenna of the perpendicularly-disposed dipole antennas that differ in phase by ninety degrees.Type: GrantFiled: December 17, 2008Date of Patent: October 18, 2011Assignee: The Boeing CompanyInventor: John E. Baldauf

Patent number: 7786945Abstract: A beam waveguide may include a first set of dual offset reflectors and a second set of dual offset reflectors. The first set of dual offset reflectors and the second set of dual offset reflectors may each include reflector geometries to produce a radiation pattern that is symmetric about a first axis between the first and second set of dual offset reflectors and to produce an axi-symmetric beam from the second set of dual offset reflectors that is unaffected by any rotation of the first and second set of dual offset reflectors relative to one another about the first axis.Type: GrantFiled: February 26, 2007Date of Patent: August 31, 2010Assignee: The Boeing CompanyInventors: John E. Baldauf, Christ P. Tzelepis, Paul C. Werntz, Tom M. Hikido
