Abstract
A compact arrangement of antennas in a glazing is disclosed, which allows a plurality of antenna wires to be connected to an external circuit by a single contact. Parallel conductors, in direct current isolation from each other so that alternating current coupling occurs between them, are embedded at different depths in the thickness of a ply of plastic material. In plan view, conductors at different depths may be positioned closer to each other than in the prior art, so antennas connected to them are less obtrusive and may even be hidden completely under an obscuration band. Different widths of parallel conductor may be used. A thin antenna, connected to a thin conductor, may be positioned in a vision area of a glazing without impeding the view.
