Description

  

      Leitungskreis        mit    einer     zwischen    den beiden parallel zueinander  verlaufenden Leitern befindlichen     Isolierstoffschicht       Die     Erfindung        bezieht    sich auf die     Weiterbildung     eines bekannten     Leitungskreis    es mit einer zwischen  der beiden parallel zueinander verlaufenden Leitern       befindlichen,

      'an den Leitern anliegenden Isolierstoff  schicht aus einem     ferromagnetischen        Werkstoff        (bri-          tische        Patentschrift    649 398). Durch die zwischen den       Leitern    liegende     ferromagnetische        Isolierstoffschicht     wird der     Induktiviltäts-und    Kapazitätsbelag stark     ver-          grössert    und damit auch bei     gegebener        geometrischer     Abmessung die elektrische Länge der Leitung.  



  Die elektrische Länge der Leitung lässt sich     weiter     verkürzen, wenn gemäss der Erfindung der magne  tische     Kreis    um jede der beiden Leiter     dadurch    ge  schlossen ist, dass zusätzlich auf den Aussenseiten     der          beiden    Leiter     Isolierstoffschichten    aus einem     ferro-          magnetischen        Werkstoff    :so angeordnet sind, dass     siie     die zwischen den beiden Leitern befindliche     Isolier-          stoffschicht    berühren.  



  Anhand der in     Fig.    1 und 2     dargestellten    Ausfüh  rungsbeispielen soll die     Erfindung    näher erläutert  werden.  



  Über den     Leitern    2 und 3, die auf eine magneti  sche     Isolierstoffschicht    1 aufgebracht sind,     befinden     sich weitere     Isolierstoffschichten    a und b, die den       magnetischen    Kreis um die Leiter 2 und 3     völlig     schliessen.

   Dadurch steigt der     Induktivitätsbelag    des  Leitungskreises wesentlich an und die elektrische  Länge     vergrössert    sich bei gegebener     geometrischer     Abmessung     ensprechend.       Zur Abstimmung eines     solchen        Leitungskreises    ist  in der     Isodienstoffschicht    a ein quer zu dem     Leiter    2  verlaufender Schlitz c vorgesehen,     in    den zur Ab  stimmung ein     Streifen    d mehr oder weniger einge  schoben ist, der     ebenfalls    eine     ,

  hohe        Permeabilität    be  sitzt.  



  In     Fig.    2 sind die auf eine flexible     Isodierstoff-          schicht    6     aufgebrachten    Leiter 7 und 8     zusätzlich    mit  Schichten e und f     überdeckt,    die seitlich über die  Leiter 7 und 8 hinausstehen und an     die        Isolierstoff-          schicht    6, die     ebenfalls    auf     ferromagnetischem    Werk  stoff besteht, anstossen, so dass der magnetische Kreis  um die Leiter 7     und    8 völlig     geschlossen    ist.

   Dadurch  wird die elektrische Länge bei     gegebener    geometri  scher Abmessung     wesentlich    erhöht.



      Line circuit with a layer of insulating material located between the two parallel conductors. The invention relates to the development of a known line circuit with one located between the two parallel conductors,

      'Insulating layer made of a ferromagnetic material lying against the conductors (British patent specification 649 398). Due to the ferromagnetic insulating material layer lying between the conductors, the inductance and capacitance coverage is greatly increased, and thus the electrical length of the line, even with a given geometric dimension.



  The electrical length of the line can be further shortened if, according to the invention, the magnetic circuit around each of the two conductors is closed by additionally arranging layers of insulating material made of a ferromagnetic material on the outside of the two conductors so that they touch the layer of insulation between the two conductors.



  Based on the Ausfüh approximately examples shown in Fig. 1 and 2, the invention will be explained in more detail.



  About the conductors 2 and 3, which are applied to a magnetic cal insulating layer 1, there are more insulating layers a and b, which completely close the magnetic circuit around the conductors 2 and 3.

   As a result, the inductance coating of the line circuit increases significantly and the electrical length increases accordingly for a given geometric dimension. To coordinate such a line circuit a transverse to the conductor 2 extending slot c is provided in the Isodienstoffschicht a, in which a strip d is more or less inserted into the vote, which also has a,

  high permeability be seated.



  In FIG. 2, the conductors 7 and 8 applied to a flexible insulating material layer 6 are additionally covered with layers e and f which protrude laterally beyond the conductors 7 and 8 and onto the insulating material layer 6, which is also made of ferromagnetic material , so that the magnetic circuit around the conductors 7 and 8 is completely closed.

   As a result, the electrical length is significantly increased for a given geometrical dimension.
