Abstract

A planar transmitter having a vertical extent and a horizontal extent, having a layer structure with a plurality of electrical circuits, wherein a first electrical circuit and a second electrical circuit are electrically conductively disconnected from one another. The transmitter also has at least one magnetic core which at least partially surrounds the layer structure and acts at least on the first electrical circuit and on the second electrical circuit, wherein the first electrical circuit and the second electrical circuit lie substantially in one plane and form one layer of the layer structure. Provision is further made for at least the first electrical circuit or the second electrical circuit to be subdivided into a plurality of electrical circuits which are electrically conductively disconnected from one another.
