2. The antenna array, in particular for ascertaining the distance between motor vehicles and their speed, having a multi-layer carrier (5);
-
a first potential surface (4), which is at ground and situated on the upper surface of the carrier (5);
coupling devices (3) disposed in the first potential surface;
a second potential surface (10), which is at ground and situated underneath the first potential surface (4), and having electric connecting sections (7), which are arranged between the first potential surface (4) and the second potential surface (10) between layers of the carrier (5) in such a way that the major part of the electromagnetic energy to be transmitted is able to be decoupled or injected via the coupling devices (3).
