Original Abstract Submitted

An inductive sensor arrangement for detecting a movement of a movable body includes a movable coupling device coupled to the movable body and a measured-value detection device comprising a circuit carrier with an exciter structure and a receiving structure. The exciter structure is coupled to an oscillator circuit which, during operation, couples a periodic alternating signal into the exciter structure. The movable coupling device is designed to influence an inductive coupling between the exciter structure and the receiving structure. An evaluation and control unit is designed to evaluate signals induced in the receiving structure and to determine a measurement signal for a current position of the movable body. The receiving structure comprises a receiving coil having at least one periodically repeating loop structure, each structure designed as a superposition in the angular direction of a sinusoidal fundamental wave and of at least one harmonic wave of the sinusoidal fundamental wave.
