Patent number: 7889142Abstract: An aircraft wing that includes a conductive ground plane adjacent the wingtip, where the ground plane conforms to an aerodynamic surface of the wing. Because the ground plane conforms to the aerodynamic surface, it has minimal impact on the aerodynamics of the wing. The ground plane can be part of a wingtip device that is detachably secured to the tip of a main wing portion. The ground plane described herein can be used on any aircraft wing structure that employs an antenna including, but not limited to, a wing of a UAV.Type: GrantFiled: August 27, 2008Date of Patent: February 15, 2011Assignee: Lockheed Martin CorporationInventor: Aaron L.

Publication number: 20110006957Abstract: A wide-bandwidth antenna (e.g., a rib-dipole antenna) includes a first pole formed by a first conductive member and/or a second pole formed by a second conductive member. The antenna also includes an antenna feed between the first conductive member and the second conductive member. The antenna also includes at least one electrically conductive element including a surface. A portion of the surface is electrically connected to, and extends from, the first conductive member or the second conductive member. The at least one electrically conductive element is capable of conducting a current that generates a magnetic field. The magnetic field lowers a total reactance of the antenna, thereby resulting in enhanced performance of the antenna and more efficient use of volume.Type: ApplicationFiled: July 13, 2009Publication date: January 13, 2011Applicant: Physical Sciences, Inc.Inventors: Francesca Sciré-Scappuzzo, Sergey N.
