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.

An encapsulated integrated circuit has transceiver circuitry operable to produce and/or receive a radio frequency (RF) signal, wherein bond pads on the IC die are coupled to the transceiver input/output (IO) circuitry. An antenna structure is coupled to the IO circuitry via the bond pads. Mold material encapsulates the IC die and the antenna structure, wherein the antenna structure is positioned so as to be approximately in alignment with a core of a dielectric waveguide positioned adjacent the encapsulated IC.

The present invention provides a substrate-embedded antenna and an antenna array constituted by said antennas. An antenna of the present invention comprises a plurality of substrates, a metal fill and a feed line. Each of the substrates has at least one through-hole. The metal fill is placed within each through-hole, and each metal fill placed therein connects one another to form a columnar metal conductor which acts as a radiating body of the antenna. The feed line is electrically coupled to the metal conductor to input and output electrical signals. A plurality of said antennas may constitute an antenna array.

During mounting to an inlay substrate, at least one end portion (including end) of an antenna wire is positioned directly over a terminal of the chip module for subsequent connecting thereto. A sonotrode is disclosed with a cutter above the capillary for cutting or nicking the wire. Insulation may be removed from a portion of the wire. The antenna may comprise two separate stubs, each having an end portion (including end) positioned over a terminal of the chip module. Additional techniques for mounting the antenna wire are disclosed.
