  • Dual polarized electronically scanned antenna
    Patent number: 6008775
    Abstract: A phased array includes a first plurality of radiators having a first polarization and a second plurality of radiators having a second polarization, different from said first polarization. The phased array is constructed such that radiating patterns of the first and second plurality of radiators are congruent. The radiators are constructed so that they radiating apertures thereof can occupy virtually the same space, i.e., the spacing of the radiating elements is less than a wavelength. Other features provided allow this compactness to be achieved. Impedance matching features are integrated into the radiators themselves. The elevation assemblies of the radiators are mated together, and then are coupled across to their respective azimuth assemblies. Two azimuth assemblies for either type of polarization may be provided when monopulse operation is required.

  • Fabrication of ferrite toroids
    Patent number: 5876539
    Abstract: A method of fabricating ferrite toroids used in ferrite phase shifters. The method employs fabrication techniques found in low temperature cofired ceramics (LTCC) tape technology and involves fabricating long rectangular through-holes, as is required by the toroid design, in layers of green ceramic tape and maintaining the integrity of the through-holes during a firing process wherein ferromagnetic ceramic oxide in the tape is converted to ferrite.

  • Electric vehicle relay assembly using flexible circuit connector coupling the relay to the relay circuit
    Patent number: 5567991
    Abstract: An electric vehicle relay assembly including a main relay and a flexible circuit electrically connected to the main relay. The relay assembly further includes a connection for mounting the flexible circuit onto the main relay and a wiring board affixed to the flexible circuit. The flexible circuit compensates for mechanical tolerance errors within the connection. The wiring board includes relay circuitry electrically connected to the flexible circuit.
