1. A method, comprising:

  • depositing a conductive trace on a circuit board, the conductive trace including a first transmission structure having a plurality of transmission sections, each transmission section having an angle of deflection relative to an axis parallel to the first transmission structure, the angle of deflection being such that, when the first transmission structure is positioned proximate to a second transmission structure to form an electromagnetic coupler, a total capacitance between the first and second transmission structures is maintained relatively constant over a range of relative positions of the first and second transmission structures, wherein the first transmission structure includes a zig-zag geometry and the second transmission structure includes a straight geometry, and wherein the first transmission structure dielectrically crosses the second transmission structure at multiple locations due to the angle of deflection.
