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 (S) 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.
Claims20
Antenna pane comprising at least one glass pane and at least one electrically conductive coating which is subdivided by barrier lines into a number of electrically isolated segments on which antenna pane the coating incorporates at least one strip-like segmented surface portion in which the distance between the barrier lines is so small that the coating there can transmit HF radiation in a specified frequency range, wherein the segmented surface portion is, by contacting in the contact areas at its two longitudinal sides and by its outer dimensions, constructed as a slot antenna for electromagnetic radiation in the range of frequencies which the segmented surface portion can transmit.
