Abstract
An angular sensor includes a base body in which a rotating element is mounted for rotation about an axis of rotation. At least one transmitting antennae is arranged on the base body and each emits a transmission signal. A reflector element extends over part of the periphery, observed tangentially in relation to the axis of rotation, reflects each transmission signal, and is arranged on the rotating element, at a radial reflector distance from the axis of rotation. A plurality of receiving antennae are arranged on the base body, the receiving antennae receiving the reflected signals as a receiving signal and supplying the receiving signal to an evaluation device. The evaluation device determines the position of rotation of the rotating element by evaluating only the receiving signals or by evaluating the receiving signals and base signals determined on the basis of the transmission signals.
