Title:
電磁結合現象を抑制するための装置
Document Type and Number:
Japanese Patent JP4156512
Kind Code:
B2
Abstract:
The invention relates to a resonance trap (8) for suppressing electromagnetic coupling phenomena for a line (1), which resonance trap includes a conductor (10) which extends parallel to and along a part of the length of the line (1). Conventional resonance traps (8) have the drawback that a direct connection exists between the RF line and the individual resonance traps (8). It is an object of the invention to provide a resonance trap (8) which enables a modular assembly on the line (1). The object is achieved by means of a resonance trap (8) of the kind set forth in which inner conductors (10) extend parallel to the line (1) and in which outer conductors (11) extend parallel to the inner conductors (10), said inner conductors (10) being arranged at a radial distance from the line (1) which is smaller than that at which the outer conductors (11) are arranged and the outer conductors (11) being arranged to cover at least partly the inner conductors (10) in the radial direction relative to the line (1). This offers the advantage that the connection between the resonance trap (8) and the line (1) is dispensed with.
