Abstract
The invention relates to a resonance trap ( ) for suppressing electromagnetic coupling phenomena for a line ( ), which resonance trap includes a conductor ( ) which extends parallel to and along a part of the length of the line ( ). Conventional resonance traps ( ) have the drawback that a direct connection exists between the RF line and the individual resonance traps ( ). It is an object of the invention to provide a resonance trap ( ) which enables a modular assembly on the line ( ). The object is achieved by means of a resonance trap ( ) of the kind set forth in which inner conductors ( ) extend parallel to the line ( ) and in which outer conductors ( ) extend parallel to the inner conductors ( ), said inner conductors ( ) being arranged at a radial distance from the line ( ) which is smaller than that at which the outer conductors ( ) are arranged and the outer conductors ( ) being arranged to cover at least partly the inner conductors ( ) in the radial direction relative to the line ( ). This offers the advantage that the connection between the resonance trap ( ) and the line ( ) is dispensed with.
