Compact non-linear geometry electromagnetic coupler for use with digital transmission systems

An apparatus comprising:

• a circuit board;
• a first conductive trace on the circuit board, the first conductive trace including a portion having a non-linear geometry;
• and
• a second conductive trace having the non-linear geometry and aligned along and positioned proximate to the portion of the first conductive trace to form an electromagnetic coupler with the portion of the first conductive trace, wherein a geometry of the electromagnetic coupler is configured to enable placement within a footprint of a card connector.

A system comprising:

• a first transmission structure including a portion having a non-linear geometry;
• a second transmission structure having the non-linear geometry and aligned along and positioned proximate to the portion of the first transmission structure to form an electromagnetic coupler with the first transmission structure, wherein a geometry of the electromagnetic coupler is configured to enable placement within a footprint of a card connector;
• the card connector coupled to at least one pad of the second transmission structure to receive a reconstructed signal;
• and
• a memory card coupled to the card connector.
