Abstract
A coil module comprises a carrier which has a polygonal basic shape with four to twelve corners and comprises a magnetic material. A coil is arranged on the carrier. The polygonal basic shape is rotationally symmetrical with an angle of 360°·2 divided by the number of corners. To produce a coil assembly, a plurality of coil modules can be connected to each other. This makes it possible to produce an efficient coil assembly for wireless electromagnetic energy transmission in a simple and flexible manner.
