  • Patent number: 10096881
    Abstract: A dielectric waveguide coupling system for launching and extracting guided wave communication transmissions from a wire. At millimeter-wave frequencies, wherein the wavelength is small compared to the macroscopic size of the equipment, transmissions can propagate as guided waves guided by a strip of dielectric material. Unlike conventional waveguides, the electromagnetic field associated with the dielectric waveguide is primarily outside of the waveguide. When this dielectric waveguide strip is brought into close proximity to a wire, the guided waves decouple from the dielectric waveguide and couple to the wire, and continue to propagate as guided waves about the surface of the wire.

  • Patent number: 7863997
    Abstract: A compact, high speed, miniaturized adaptive controller for a microwave power generator. A pair of directional couplers are arranged between a microwave source and a circulator to measure forward and reverse power. An electromagnet in the circulator may be controlled in response to a VSWR calculation. In some arrangements, the directional couplers may be loop-type directional couplers that are integrated into a waveguide magnetron launching assembly. The directional couplers may use a tapered coaxial line that presents an impedance that reduces along the length thereof. This enhances the directivity of the loop coupler and improves performance of the controller.

  • Patent number: 7804381
    Abstract: A waveguide for use in apparatus for receiving transmitted data signals is provided. The waveguide includes first, second and third channels with the received data entering the first channel and components of the received data, signals being selectively deflected from the first channel into the second or third channels. The form of the components depends on whether the data signals have circular or linear polarity. The components leave the waveguide in substantially the same phase as which they entered the waveguide thereby allowing the same to be subsequently processed. The provision of the waveguide allows the receiving apparatus to be used to receive data signals with either circular and/or linear polarity and be subsequently processed.

  • Patent number: 7755450
    Abstract: A waveguide correlation unit and a method for manufacturing the same are disclosed. The waveguide correlation unit includes stacked first and second waveguide plates having an identical configuration, wherein a central coupling plate is disposed therebetween. Due to the identical configuration of the first and second waveguide plates, mechanical uncertainties may significantly be reduced, since both plates may be formed in a common process without the repositioning activities during the manufacturing process.

  • Patent number: 7561013
    Abstract: An LSE mode, which is a parasitic mode, can be effectively suppressed by a simple structure, and a reduction in size and weight can be thereby facilitated. Further, a metal body 3 is arranged in the vicinity of a dielectric waveguide 1 of an NRD guide to suppress the LSE mode, the NRD guide being configured to propagate electromagnetic waves through the dielectric waveguide 1 which is sandwiched between parallel conductor plates with a gap of less than a ½ wavelength. This metal body 3 has an arbitrary shape, and may have a discoid shape, an elliptic shape or a prismatic shape. Furthermore, an even distance d is maintained between the metal body 3 and the dielectric waveguide 1, and a phase constant difference can be suppressed by changing this distance d.

  • Patent number: 7382215
    Abstract: In one implementation, a method is provided for an image guide coupler. The method includes controlling a coupling between adjacent waveguides of a propagating wave by controlling a coupling through at least one field pick up probe positioned next to the adjacent waveguides. In some implementations, controlling the coupling through the at least one field pick up probe includes using a series connected switch. In some implementations, the method includes controlling the coupling through the at least one field pick up probe using a pin diode, a transistor, a MEMS switch, or a varactor, in series with the at least one field pick up probe.
