  • Patent number: 6396449
    Abstract: A layered, electronically scanned antenna. The antenna includes a plurality or array layers separated by dielectric spacers. Each array layer includes a transistor switched grid formed by a plurality of reflective/transmissive elements such as cross dipoles interconnected by a plurality of semiconductors, such as MOSFETs. When the switched grid is in an open state, its associated array layer is reflective. When it is in a closed condition, its associated layer is in a transmissive state. By controlling the state of each array layer, a desired degree of phase shift can be imparted to the signal reflected by the antenna. The antenna thus eliminates the need for costly MEMS/MMIC technology to achieve the desired degrees of phase shift of a signal reflected by the antenna.

  • Patent number: 6351247
    Abstract: A polarization twist, space-fed, E-scan planar phased array antenna. The phased array antenna incorporates a polarization twist, space-fed architecture. A plurality of unit cells are formed wherein each cell incorporates a large plurality of phased array elements and associated phase shifters. The space-feed architecture enables 2-bit phase shifters to be employed while still producing low antenna sidelobes. The phased array elements, phase shifters, and associated control circuits for controlling the phase shifters are all preferably formed on one surface of a MMIC substrate. This further simplifies significantly the cost and complexity of manufacturing and testing the E-scan phased array antenna. The antenna can therefore be used in applications where an E-scan phased array antenna would have been too costly to employ.

  • Patent number: 5515009
    Abstract: A spatial power combiner includes a circularly corrugated horn 26, a meniscus lens 28, an amplifier array 16, and a layer of microwave absorbing material 34 on a housing interior 32. The lens 28 receives polarized microwave radiation from the horn 26 and collimates it, renders it in phase and with nearly uniformly amplitude, and distributes it across the lens aperture. The amplifier array 16 amplifies the radiation and re-radiates it, orthogonally polarized, to the lens 28, which focuses it back down the horn 26. An array of parasitic micropatches 24 between the lens 28 and amplifier array 16 provides impedance matching. A quarter-wave anti-reflecting coating 30 covers both surfaces of the lens 28. The microwave absorbing material 34 reduces or prevents resonance of higher order modes.

  • Patent number: 5483241
    Abstract: A millimeter wave radar is placed on an aircraft and several radar targets are placed near a runway. The targets are discrete objects, each having a relatively localized radar cross section, a unique signature or a unique range bin, and a position which is accurately known. Targets should be spread over the length of the runway. Radar corner reflectors and active or passive repeaters are preferred. The locations of the radar targets with respect to the runway can be transmitted to the aircraft, or they can be stored on board. On board memory requirements can be reduced by requiring all airports to select one of only a few standard target placement patterns, or even only one. Targets are inexpensive, as are radars whose only precision requirement is in range, and not in azimuth or elevation angles. Range to at least three targets in the radar's field of view is all that is required for an on-board computer to determine the aircraft's location.

  • Patent number: 4555708
    Abstract: A NAVSTAR satellite has a navigation antenna array beamed toward the earth. A communications antenna array for communicating with other satellites requires a pattern null near the axis and high gain to the sides with minimum losses. This is achieved with a dipole ring array comprising eight elements surrounding the navigation array. The ring has a diameter of 1.1 wavelength, and is fed with equal amplitudes and a third mode phase progression, which produces good circular polarization in the far field. For a different sized dipole ring, there will still be an optimum phase distribution which will give good circularly polarized patterns.
