Patent number: 11476584Abstract: An apparatus for an antenna assembly, which can be used for a mobile application such as on an aircraft, can include a housing defining an interior. A first antenna, such as a WAAS GPS antenna, can mount within the interior to operate at a first frequency. A second antenna, such as an L-band monopole antenna, can mount within the interior of the housing. A trap coupled to the second antenna can be tuned to the first frequency to prevent signal loss caused by the second antenna.Type: GrantFiled: August 18, 2017Date of Patent: October 18, 2022Assignee: R.A.

Patent number: 9490524Abstract: A spring boot for use with an antenna comprises a cylindrical main body having an annular flange at the lower end thereof, and an annular rim at the upper end thereof. The flange has a plurality of mounting holes therethrough. The interior of the spring boot is hollow and is configured to match the shape of the antenna spring. When installed, the spring boot is fitted over the spring, and seated on an antenna mount, encircling the spring. Fasteners are installed through the mounting holes on the flange to affix the spring boot to corresponding bores in the mount. A washer is positioned atop the rim and is fixed between the antenna core and the spring. This configuration effectively constrains the spring boot between the core and the mount, so as to provide added damping to the antenna spring.Type: GrantFiled: May 6, 2011Date of Patent: November 8, 2016Assignee: R.A.

Patent number: 9413063Abstract: The use of rectennas, or antenna-coupled rectifiers, using metal-insulator-metal tunnel diodes as rectifiers for energy conversion has been explored with more fervor recently, given the advances in nanotechnology fabrication and increased resolution of features. Some have made these devices from symmetric metals (e.g. Ni—NiO—Ni) and asymmetric metals (e.g. Al—AlOx/Pt), and have used deposited oxides as well as native oxides. One key to obtaining a highly asymmetric device with efficient current generation needed for high conversion efficiency is to instead use dissimilar metals and a thin reproducible oxide. The described method allows for a thin, reproducible native oxide of nickel be integrated with any antenna metal to overcome oxide surface roughness problems that typically hamper the practicality of these devices.Type: GrantFiled: June 16, 2015Date of Patent: August 9, 2016Assignee: R.A.
