Abstract
An antenna pane for use, for example, as a vehicle window, comprises a glass pane (1) carrying an electrically conductive coating (3). The coating (3) includes a strip-like portion (5) divided into electrically isolated segments by barrier lines (4) spaced so the coating transmits HF radiation in a specified frequency range and constructed, by contacting in contact areas (7) at its two longitudinal sides (6) and by its outer dimensions, as a slot antenna for frequencies in said range.
