Rotation angle sensor or length sensor
First Claim
1. A rotation angle sensor having at least two stripline oscillators, which comprises respective striplines as sensor elements of a type in a form of so-termed microstrips fixed to a dielectric support such that the stripline oscillators are arrayed in a curve, for angle measurement, such that at least one actuating element is passed by relative movement over the curved array, and the striplines in the form of so-termed microstrips are of such a shape that the at least one actuating element covers more than one of the stripline oscillators.

Abstract
A rotation angle sensor with two or more oscillators which comprises, in each case, striplines fixed on a dielectric support, as sensor elements, such that the oscillators are arrayed in a curve, for angle measurement, or they are arrayed in a straight line, for position measurement. One or more actuating elements, for example eddy-current actuating elements, are passed over the curve or the line to cause relative movement. The striplines are shaped so that the one or more actuating elements (B1, B2) cover more than one oscillator.
