Title: INTRUSION DETECTION PANE ASSEMBLY
Abstract:
The present invention relates to an intrusion detection pane assembly (10, 10’) which comprises: - at least one first pane (1) which consists of tempered glass and has an outer surface (I) and an inner surface (II), - at least one transparent, electrically conductive coating (3) which is applied to the inner surface (II) of the first pane (1), and - a sensor unit (20) having a transmitting unit (20.1), an antenna (21) and an evaluation unit (20.2), the transmitting unit (20.1) transmitting at least one high-frequency voltage signal of a frequency f of 0.1 GHz to 6 GHz to the antenna (21) and the antenna (21) emitting electromagnetic radiation of the frequency f, and the evaluation unit (20.2) measuring the impedance matching of the transmitting unit (20.1) to the antenna (21). The antenna (21) is electromagnetically coupled to the transparent, electrically conductive coating (3) and the sensor unit (20) outputs an alarm signal if the measured impedance matching deviates from a comparison value.
