  • Patent number: 9077087
    Abstract: Systems and methods in which antenna system configurations use over-coupling between a plurality of antenna elements for effectively providing wide-band operation are shown. Such over-coupling comprises a multiple antenna element configuration in which adaptation to one antenna element (e.g., an influencing antenna element) results in substantial operational frequency band adaptation to a second antenna element (e.g., a respondent antenna element). Over-coupling results in a frequency split at the second antenna, whereby the resonate frequency of the antenna element is split into a plurality of frequency bands. By implementing such frequency splitting with respect to otherwise narrow band antenna elements, the over-coupled antenna system may be made to effectively provide wide-band operation.

  • Patent number: 9035838
    Abstract: An antenna implementation comprises an electromagnetic lens and at least one electromagnetically shielding member. The electromagnetic lens is adapted to guide at least one electromagnetic signal by means of at least a variation in permittivity. The at least one electromagnetically shielding member encapsulates the electromagnetic lens partially so as to direct at least one electromagnetic signal propagating through the electromagnetic lens. The at least one electromagnetically shielding member can advantageously be part of an enclosure; said enclosure encapsulates partially the electromagnetic lens. The antenna can further comprise antenna transmission means that contain wave guides. Said waveguides can advantageously be incorporated into the enclosure. The antenna is particularly suited for implementations using Substrate Integrated Waveguide techniques. SIW techniques allow miniaturization of the antenna and offer the advantage of low energy consumption as may be required in portable devices.

  • Publication number: 20150097743
    Abstract: System for positioning a reflector includes a base (112), yoke (104) and a reflector in the form of a lens mirror assembly (10). A motor (120) is mounted and remains substantially stationary with respect to rotation about a first axis while the yoke rotates about the first axis. A connecting rod (152) actuated for movement by the motor is mechanically coupled to the reflector so that movement of the connecting rod in relation to the yoke imparts rotation to the reflector about the second axis when the reflector is supported by the yoke. A mechanical drive system couples an output shaft of the motor to the connecting rod. The mechanical drive system is arranged so that it varies an angular position of the reflector at a rate which is linearly related to the rotation of the output shaft.
