ABSTRACT:
An automotive glazing, comprising an antenna connector is disclosed. The glazing comprises at least a first ply of a transparent glazing material, and a ply of a plastics material extending across the ply of glazing material and having a line-like electrical conductor in contact therewith, a portion of the electrical conductor line being configured to form an antenna conductor and a portion being configured to form a coupling region. In addition, a surface contact is provided on the surface of the first ply of glazing material situated away from the plastics material, in registration with the coupling region. The coupling region and the surface contact form a transmission line acting as a bandpass filter for a frequency band f, the portion of the electrical conductor forming the coupling region having a length approximately equal to an odd multiple of a quarter of a first effective wavelength λeffin the glazing corresponding to f. Signals received by the antenna in the bandwidth are transferred between the coupling region and the surface contact by low-impedance radio frequency coupling. Preferably, the surface contact and the coupling region form a two-line transmission line.
