  • Patent number: 9484632
    Abstract: An antenna system comprising a plurality of loop antenna sets with each of the plurality of loop antenna sets disposed in one of a plurality of different parallel planes with each of the planes being spaced apart from another adjacent plane and wherein loop antenna set in the plurality of loop antenna sets comprises a plurality of loop antennas and wherein the plurality of loop antennas are configured such that the near field inductive coupling between the plurality of loop antenna sets is zero. The absence of inductive coupling between the loop elements provides a frequency-independent means for multiplexing signals for transmission and reception by the multiple loop antenna system.

  • Patent number: 9397400
    Abstract: A multiple input loop antenna comprising one or more half-loop antennas disposed above a ground plane wherein the plane of each half loop is perpendicular to the ground plane such that the multiple input loop antenna is a three-dimensional structure and electromagnetic waves are radiated from points within the volume occupied by the antenna rather than from a two-dimensional surface. For this reason, the multiple input loop antenna can radiate levels of peak power without inducing excessive air breakdown which are relatively high compared with peak power levels of conventional antennas having comparable transverse dimensions. Also described is an array antenna comprised of an array of multiple input loop antennas.

  • Patent number: 9260026
    Abstract: A non-contacting position sensing apparatus includes at least one vehicle-mounted receiver coil that is configured to detect a net flux null when the vehicle is optimally aligned relative to the primary coil in the charging device. Each of the at least one vehicle-mounted receiver coil includes a clockwise winding loop and a counterclockwise winding loop that are substantially symmetrically configured and serially connected to each other. When the non-contacting position sensing apparatus is located directly above the primary coil of the charging device, the electromotive forces from the clockwise winding loop and the counterclockwise region cancel out to provide a zero electromotive force, i.e., a zero voltage reading across the coil that includes the clockwise winding loop and the counterclockwise winding loop.
