An alarm pane assembly is presented. The assembly includes a pane made of tempered glass, a transparent, electrically conductive coating arranged on a surface of the pane, a sensor unit, and an antenna. According to one aspect, the sensor unit includes a transmitting unit and an evaluation unit. During operation, the transmitting unit forwards a high-frequency voltage signal with a frequency f in a range of 0.1 GHz to 6 GHz to the antenna, the antenna emits electromagnetic radiation of the frequency f, the evaluation unit measures the impedance matching of the transmitting unit to the antenna, and the sensor unit outputs an alarm signal when the measured impedance matching deviates from a reference value. According to another aspect, the transparent, electrically conductive coating has a region with at least one coating-free pattern that overlaps the area of the orthogonal projection of the antenna onto the transparent, electrically conductive coating.
