Definitions

  • the present invention relates to a support for microwave transmission line with conductive tape, in particular of the triplate type.
  • Such supports are known, in particular in the field of air triplate lines. These supports are intended to provide mechanical support for the interior conductor of the line and are arranged as a spacer between the ground planes or between a ground plane and the interior conductor.
  • the present invention aims to remedy these drawbacks.
  • It relates to a support for microwave line of reduced mass and volume integrated into the impedance of the line and ensuring excellent resistance to vibrations and minimized disturbance of propagation in the transmission line.
  • a support for microwave transmission line with conductive tape in particular of the triplate type, characterized in that it comprises a tape made of dielectric material folded in accordion, each fold having a longitudinal slot so as to be able inserting the ribbon of said line into said accordion support and the width of the slot being adapted to the thickness of said ribbon of the line, and protrusions protruding from at least one side of the ribbon to ensure the positioning of the ribbon of dielectric material and of the line that it supports with respect to at least one ground plane against which it is supported by said side, these protrusions coming lodge in corresponding holes of said ground plane.
  • FIG. 1 partially represents, in perspective, a conductive strip 1 of a microwave transmission line which is mechanically held by a support essentially consisting of a strip 2 of dielectric material such as that known under the brand Mylar.
  • This ribbon 2 is folded in an accordion and has longitudinal slots 21 arranged in the center of the folds of the ribbon. These slots have a width corresponding to the thickness of the conductive tape 1 of the line to be maintained and a length allowing the pleats to be arranged with a given angle relative to a transverse plane perpendicular to the axis of the tape 1.
  • a transmission line of the air triplate type comprising an internal conductive tape 1 kept equal distance between two parallel ground planes 3 and 4, without this in any way limiting the invention.
  • dotted lines 20 are cut which allow the ribbon 2 to be folded after machining without the need for any tools. Folding can for example be done manually. When the folds are tight against each other, it is very easy to thread the conductive tape 1 into the slots 21. When the folds are released, due to the elasticity of the material, the support takes the form shown in FIG. 1 with the folds apart from each other.
  • the strip of dielectric material 2 has on each side of the protuberances 22 cut from the same material at the same time as the rest of the ribbon 2. These protuberances 22 are preferably arranged at the bending angles and they are designed to engage in holes corresponding 10, 10 ′ of the ground planes 3, 4 (partially shown) to ensure the positioning of the assembly.
  • the width of the strip 2 is chosen so that, the protrusions being engaged in the corresponding holes of the ground planes, the sides of the strip 2 are substantially in contact with the ground planes. This ensures very efficient and precise mechanical maintenance of the transmission line, with excellent resistance to vibrations.
  • the protuberances 22 may only be provided on one side of the conductive strip 1, that is to say at a folding angle in two. One could also imagine placing these outgrowths at other points on the sides of the tape than the folding angles. On the other hand, it is also possible to give these protuberances 22 shapes such that they can engage with snap-fastening in the holes of the ground planes, the support then contributing to the mechanical maintenance of the ground planes.
  • the support to be used for the three-ply lines must meet the following criteria: - ensure proper centering of the line; - maintain vibration; - allow the thermal expansions of the line, particularly if the interior conductive tapes and the ground planes are not made of the same conductive material; - use little dielectric to minimize losses.
  • the support according to the invention fulfills all these criteria. But it brings many additional advantages: - it is integrated into the line impedance; - The protuberances 22 provide centering and can also allow the support to be fixed by snap-fastening; - the support is ventilated and allows good cooling of the line.
  • Figure 2 shows a fold of the support 2 seen from the front. It can be seen that the central part of the slot 21 is widened by a clearance 23, which decreases the amount of dielectric material and allows the circulation of air.
  • FIG. 3 represents another variant of support according to the invention in which the slots 121 are displaced so as to be arranged astride a folding angle on two of the strip 102.
  • This support also furthermore comprises folding dotted lines 120 and centering and fixing protuberances 122, which exist here only on the side opposite to the slots.
  • Such a support is particularly useful for maintaining closed lines, as can be seen in Figure 4.
  • an inner conductive ring tape 30 having accesses 31.
  • the support 102 is inscribed inside the ring, centering holes 110 being made only in the center of the ring, in correspondence with the protuberances 122.
  • the production of the supports according to the invention can be done with tight tolerances by machining the Mylar strip, for example by laser ensuring the cutting of the tape with its protuberances and slots and dots.
