MEASUREMENT OF ANGLE OF ROTATION USING MICROSTRIP RESONATORS (2.4 GHZ, 2 DEGREE)

摘要

The present invention relates to a measuring device and a method for contactless detection of an angle of rotation or a torsional rotation. The measuring device includes a first resonator ( 2 ) and a second resonator ( 4 ). The two resonators ( 2, 4 ) have an essentially circular circumference, on which at least one protrusion and/or one recess is disposed. The two resonators ( 2, 4 ) are coplanar to one another and are also rotatable relative to one another. In addition, an exciter device ( 6 ) for exciting the resonators and a receiver device ( 6 ) for measuring a backscattered signal are present. Upon a relative rotation of the two resonators ( 2, 4 ) to one another, the resonant frequency changes, which is used as a measure for ascertaining the angle of rotation.
