Abstract
A system is provided in which a first waveguide has a first resonator coupled to an end of the first waveguide. A second waveguide has a second resonator coupled to the second waveguide. The first resonator is spaced apart from the second resonator by a gap distance. Transmission of a signal propagated by the first waveguide across the gap to the second waveguide is enhanced by a confined near field mode magnetic field produced by the first resonator in response to the propagating wave that is coupled to the second resonator.

A system comprising:
- a first waveguide having a first resonator coupled to an end of the first waveguide;
- a second waveguide having a second resonator coupled to the second waveguide;
- and
- in which the first resonator is spaced apart from the second resonator by a gap distance.
A system comprising:
- a first module, in which the first module includes:
- a substrate on which is mounted a radio frequency (RF) transmitter circuit coupled to a first waveguide coupler located on the substrate;
- a housing that surrounds and encloses the substrate, the housing having a first port region on a surface of the housing;
- a first waveguide located between the first waveguide coupler and the first port region on the housing;
- and
- a resonator adjacent to an end of the first waveguide at the first port region.
A method for transmitting a signal through multiple waveguides, the method comprising:
- propagating the signal through a first waveguide in a guided wave transmission mode;
- converting the guided wave signal into a confined near field mode magnetic field by a first resonator at an end of the first waveguide;
- magnetically coupling the magnetic field to a second resonator at an end of a second waveguide, in which the second resonator is separated from the first resonator by a gap distance;
- and
- converting the magnetic field back into a guided wave by the second resonator such that the signal propagates through the second waveguide in a guided wave transmission mode.
