Component with electromagnetic coil and variable capacitance has at least one conductor winding forming coil; variable capacitance is formed by varying distance between plate and coil

摘要

The device has an electromagnetic coil and a variable capacitance with at least one conductor winding (1) forming the coil and a metal plate (2) arranged to form a variable capacitance between the metal plate and the coil by varying the distance between the metal plate and the coil. A planar coil with several windings can be used.
