A coupling mechanism for (non-radiative) coupling through a dielectric medium, such as the glass of an automobile window, a radiofrequency (RF) antenna signal. The coupling mechanism includes a coaxial conductor for providing the RF antenna signal to a slotline structure (consisting of a layer of metal, deposited on one side of a dielectric substrate such as a circuit board, in which a slot is formed to a depth reaching to the dielectric substrate) mounted typically by an adhesive on one side of the dielectric medium/window glass. On the other side of the dielectric medium/window glass, the coupling mechanism uses either a second slotline structure or a microstrip positioned so as to provide optimal coupling across the dielectric medium/window glass.
