Abstract
An electromagnetic (EM) coupler including a first transmission structure having a first geometry, and a second transmission structure having a second geometry and forming an EM coupler with the first transmission structure, the first and second geometries being selected to reduce sensitivity of EM coupling to relative positions of the first and second transmission structures is disclosed.
Claims17
An apparatus comprising:
- a circuit board;
- and
- a conductive trace on the circuit board, the conductive trace including a transmission structure having a plurality of transmission sections, each transmission section having an angle of deflection relative to an axis parallel to the transmission structure, such that the angle of deflection of each transmission section enhances electromagnetic coupling of the transmission structure.
An apparatus comprising:
- a circuit board;
- a conductive trace on the circuit board;
- and
- a first transmission structure having a selected geometry and connected to the conductive trace, such that said transmission structure is capable of forming an electromagnetic couple with a second transmission structure when said first and second transmission structures are proximate to each other, said electromagnetic couple having at least three fringe capacitance regions.

An apparatus comprising:
- a circuit board;
- conductive means for conducting a signal, said conductive means on the circuit board;
- and
- a first transmission means for receiving the signal from said conductive means and for transmitting said signal, said first transmission means having a selected geometry, such that said first transmission means is capable of forming an electromagnetic couple with a second transmission means when said first and second transmission means are proximate to each other, said electromagnetic couple having a plurality of parallel plate capacitance regions and three or more fringe capacitance regions.
