The first element has a vertical conductive strip arranged in an area of the space between the heater element and a lateral edge of the window glass. The first element further has in an area of the space above the first antenna or in a space defined between the upper and lower ends of the first antenna, at least one horizontal conductive strip or a T-shaped or inverted T-shaped conductive strip assembly having a longer horizontal strip portion and a shorter vertical strip portion, or at least two horizontal conductive strips connected at opposite ends by vertical conductive strips to constitute a rectangular loop, or at least two horizontal conductive strips connected at one ends by a vertical conductive strip to constitute a -shape.
