    Abstract: PROBLEM TO BE SOLVED: To accomplish a function capable of communicating with a satellite and/or a terrestrial system and a function capable of receiving radio frequency signals having circularly polarized waves and/or linearly and vertically polarized waves.
    SOLUTION: The present invention relates to an antenna system for receiving both circularly polarized radio wave signals and linearly polarized radio wave signals, the circularly polarized radio signals arriving at the antenna system from a direction normal or oblique to a major surface of the antenna system and the linearly polarized radio signals arriving at the planar antenna system from a direction acute to the major surface. The antenna system includes a high impedance surface and a plurality of antenna elements disposed on the high impedance surface, the plurality of antenna elements being arranged in such a pattern on the surface that first selected ones of the antenna elements are responsive to circular polarization and second selected ones of the antenna elements are responsive to linear polarization.

    Abstract: A micro-electromechanical system (MEMS) switch (124) formed on a substrate (110), the switch comprising a transmission line (114) formed on the substrate, a substrate electrostatic plate (120) formed on the substrate, and an actuating portion (126). The actuating portion comprises a cantilever anchor formed on the substrate and a cantilevered actuator arm (130) extending from the cantilever anchor. Attraction of the actuator arm toward the substrate brings an electrical contact (134) into engagement with the portions of the transmission line (114) separated by a gap, thus bridging the transmission line gap and closing the circuit. In order to maximize electrical isolation between the transmission line (114) and the electrical contact (134) in an OFF-state while maintaining a low actuation voltage, the actuator arm (130) is bent such that the minimum separation distance between the transmission line (114) and the electrical contact (134) is equal to or greater than the maximum separation distance between the substrate electrostatic plate (120) and arm electrostatic plate (132).

    Abstract: A multiple band reconfigurable reflecting antenna array and method for mulitple band operationand beam steering. An array of dipole antennas is disposed on a multiple band high impedancesurface. The antenna array is reconfigured by changing the length of the dipole elements, tothereby change the dipoles resonant frequency. At a given frequency band, small changes in dipole length allow to steer the reflected beam in the selected direction; whether large changes indipole length permit to switch the operating frequency band. A method of broadening thebandwith of a high impedance surface is also exposed.

    Abstract: A method and system for wireless Direct To Home satellite services signal distribution to a plurality of service requesting users. A multi-user transmitter is coupled to an earth satellite antenna to receive selectable satellite transponder signals. The multi-user transmitter includes a plurality of transponder selectors, each transponder selector preferably being associated with or even dedicated to a respective service-requesting user. Each service-requesting user is provided with a user-controllable channel selector for accessing the selectable satellite transponder signals. The user-controllable channel selector is coupled to a respective user display unit and to a respective user receiver unit. A responder, which may be in the user receiver unit, is responsive to a service-requesting user-selected channel signal for transmitting a transponder selection signal to the multi-user transmitter. The transponder selection signal contains information indicative of a desired satellite transponder signal, to be transmitted to the service-requesting user associated with the respective (typically user-selected) channel signal. The multi-user transmitter transmits the selected satellite transponder signals to each of the plurality of service requesting users in response to the transponder selection signals, and may do so by broadcasting. The desired satellite transponder signal is then coupled to the service-requesting user receiver (which may contain the user-controllable channel selector) for display by the respective user display unit.
