Abstract: A window pane antenna suitable for radio communication, for automobiles, consists of a loop-shaped antenna conductor (6) and of a conductive area (8) disposed in the edge zone of the glass pane (1). The feed point (7) of the antenna conductor (6) is disposed in the immediate vicinity of the conductive area (8, 9, 10) without connection to it. The other end (6′) of the antenna conductor (6) is in electrically conducting connection with the conductive area (8, 9, 10). In comparison with known antenna structures for radio communication, the tuning behavior of this antenna structure is comparative insensitive to mechanical tolerances during installation of the antenna window pane.

Abstract: A method and apparatus for extruding a plastic spacer directly on an object, in particular on the periphery of window glazing, such as automobile glazing intended to be glued into the opening of a vehicle. In particular the invention relates to properly producing the connection zone between the end and the beginning of the extruded spacer when it forms a closed loop. According to the invention the beginning of the spacer and the remainder of the loop are extruded, with the exception of the connection zone. The object is then provided with an applied anti-adhesive deposit surface that is continuous with the surface of the object. The path of the extrusion head is diverted in relation to the surface of the object so that the extrusion occurs on the applied deposit surface, proximate to and beyond the beginning of the spacer loop. The extruded spacer is then allowed to harden and the extremities of the spacer are cut and adjusted to properly complete the connection.
