ABSTRACT:
A coupling structure for coupling a device operable at a radio frequency with a body is formed of a polymeric material loaded with a conductive filler. A portion of the surface of the body defines a coupling area of a predetermined shape that receives a conductive pad having a shape and area corresponding to the predetermined shape and coupling area. The conductive pad is positioned on the surface of the body in non-penetrating contact with the body such that, in use, the pad and the body have an impedance, substantially capacitively reactive in nature, defined therebetween that is less than the impedance of the body at the operating frequency, thereby facilitating the transfer of electromagnetic energy at the operating radio frequency between the body and the pad.
