1. Apparatus, comprising:
- a first transmission structure; and
a second transmission structure having a plurality of transmission sections, each transmission section having an angle of deflection relative to an axis parallel to the second transmission section, wherein the angle is selected such that, when the second transmission structure is positioned proximate to the first 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.

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.
