Abstract
A sensor element is for testing a planar data carrier that has a spin resonance feature. The sensor element includes: a magnetic core having an air gap into which the planar data carrier can be inserted for testing purposes; a polarization device for generating a static magnetic flux in the air gap; and a resonator device for exciting the spin resonance feature of the data carrier to be tested in the air gap. The resonator device has a stripline resonator and a supply structure for the stripline resonator and is designed to generate a high-frequency field with circular polarization owing to the geometry of the stripline resonator and/or the geometry of the supply structure.
