    Abstract: A method and system for an integrated transceiver is presented. The integrated transceiver includes a transceiver housing, where a waveguide is formed inside the transceiver housing using a transceiver housing and a sub-floor component. Neither transceiver housing nor the sub-floor component alone is configured to operate as a waveguide. The integrated transceiver can include a transceiver housing that forms a portion of an integrated waveguide assembly, where the transceiver housing alone does not form the waveguide, and another portion of the integrated waveguide assembly couples with the transceiver housing to form the waveguide of the integrated waveguide assembly. Further, the integrated waveguide portion of the sub-floor component can be a flat surface, where the integrated waveguide portion of the transceiver housing comprises substantially all the features of said integrated waveguide.

Hence, the line length Li of each rectangular waveguide tube can be arbitrarily set, while maintaining a phase relationship between high frequency signals transmitted by each rectangular waveguide tube.

  • Publication number: 20110181303
    Abstract: Systems and methods for detecting electromagnetic waves are disclosed. A system for use in detecting an electromagnetic wave includes an inductive device and a spintronic device. The inductive device generates an induced electromagnetic field when the inductive device receives the electromagnetic wave. The spintronic device has an impedance that changes when exposed to the induced electromagnetic field from the inductive device. The change in impedance is indicative of the electromagnetic wave received by the inductive device. Another system for use in detecting or transmitting an electromagnetic wave includes a conductive device and an inductive device. The inductive device is configured to generate an induced electromagnetic wave when the inductive device receives an electromagnetic wave passed by the conductive device. Another system for detecting electromagnetic wave permittivity or permeability of an object includes a pair of antennas and an inductive device.

  • Publication number: 20110158344
    Abstract: An electronic device provided with a plurality of circuit boards uses a support member for supporting the circuit boards as the transmission path of a wireless signal. For example, the electronic device is provided with a first printed circuit board for processing a millimeter-wave signal, a second printed circuit board which is signal-coupled to the printed circuit board and receives the millimeter-wave signal to subject the received signal to signal processing, and a waveguide which is disposed with a predetermined dielectric constant between the printed circuit boards, wherein the waveguide constitutes the dielectric transmission path, and the waveguide supports the printed circuit boards. This configuration makes it possible to receive the electromagnetic wave based on a millimeter-wave signal radiated from one end of the waveguide constituting the dielectric transmission path, at the other end thereof.
