  • Superconducting ultrabroadband antenna
    Patent number: 6363268
    Abstract: A transmission line antenna assembly having a substantially continuous bandwidth from the microwave region of the electromagnetic spectrum to the VHF region of the spectrum. The antenna assembly includes at least one balanced transmission line antenna element of high-temperature superconductor material supported by a substrate, an antenna cavity supporting the substrate and containing a thermally-conductive electromagnetic-energy-absorbing material therein, and a cryogenic cooler for cooling the antenna element to a temperature at which it exhibits superconductivity.

  • Dual polarized ambidextrous multiple deformed aperture spiral antennas
    Patent number: 5227807
    Abstract: An antenna group comprising a plurality of spiral antennas occupies a circular space. The spiral antennas are radially symmetrically arranged about a point at the center of the circle. Each spiral antenna is deformed to occupy a substantially all of the area within a sector of the circle. The antenna may be used for detection of circularly-polarized waves of either polarization sense, or may operate with phase-sensing means to locate the source of incoming electromagnetic radiation.

  • Missile having reduced mass guidance system
    Patent number: 4600166
    Abstract: A guided projectile (11) is provided with a gyroscope (29) having a spherical rotor (41). The rotor (41) is supported at its outer spherical surface by a stator (42) using fluid bearing techniques. The stator (42) is fixed to the projectile's housing (38) so that the gyroscope (29) is operated in a strapdown mode.The structure of the gyroscope (29) and particularly the stator (42) places very little material along its center axis of the projectile (11). This is particularly useful where the projectile's warhead (17) functions by squirting a stream (25) of metal through a target's armor, and any material in the way of the stream (25) would tend to diminish the lethality of the projectile (11). The spherical configuration of the rotor (41) and the use of the stator (42) as a support bearing also provides a method of supporting the rotor (41) during conditions of high acceleration which are experienced in cannon launch of the projectile (11). Other advantages include light weight, low cost and high reliability.
