Definitions

  • the present invention relates generally to transmission lines of electromagnetic waves, and relates more particularly to a transmission line of the air triple plate type operating at microwave frequency.
  • a line of the air triplate type comprises two parallel conductive plates, distant from each other, and electrically folded back to each other, the space separating these two plates being filled with air serving dielectric, and a central conductive tape interposed between the two plates, and parallel to them.
  • the object of the present invention is to solve this problem by proposing a transmission line of the air triple plate type with dielectric pieces of support profiled so as to avoid any disturbance of the field inside the line.
  • the line has the advantages of being inexpensive, of being light in weight, of having very good power handling, of generating low losses, of being able to be mass produced, and of be able to be very long.
  • the subject of the invention is a microwave transmission line comprising two parallel conductive plates distant from one another and electrically connected to each other, the space separating these two plates being filled with air, a central conductive strip interposed between the two plates and parallel to them, and two sets of parts forming supports of dielectric material each arranged along one of the two sides of the ribbon, each support being integral with the two conductive plates and being provided with a notch in which the ribbon is positioned so as to be held in place, characterized in that each of the two sets of supports consists of a plurality of supports distributed along one of the two sides of the ribbon and in that each support is in the form of a parallelepiped block comprising a tapered longitudinal extension at the end of which the notch is formed, the two conductive plates being respectively in support on the lower and upper faces of each block.
  • the invention also relates to a use of the microwave transmission line according to the invention, this use being characterized in that the line constitutes a power divider of great length supplying a set of radiating sources arranged in alignment.
  • a microwave transmission line 1, of the air triplate type in accordance with the invention, comprises two rectangular conductive parallel plates lower 2a and upper 2b, of width I and of length L, spaced from each other by a distance d and electrically connected to each other, and a conductive strip 3, of thickness e, interposed in the middle of the two plates 2a and 2b, and parallel to these.
  • the space separating the ribbon 3 from the respective plates 2a and 2b is filled with air.
  • the two conductive plates 2a and 2b, and the conductive tape 3, are made of a metal with good conductivity, such as for example electrolytic copper.
  • the central strip 3 is obtained either by chemical cutting or by machining.
  • the two conductive plates 2a and 2b can be replaced by two plates of dielectric material covered with a metallization, without departing from the scope of the invention.
  • the triple air line 1 also comprises a plurality of parts forming supports 5 according to a first embodiment, made of dielectric material having a low tangent of losses, distributed alternately on each side of the central strip 3, and over the entire length of said ribbon.
  • the distance separating two alternating supports 5 is equal to ⁇ / 4.
  • each support 5 is in the form of a parallelepipedal block 6a extending longitudinally by an additional block keep quiet 6b of substantially triangular shape in longitudinal section.
  • a notch 8 At the end of the block 6b is formed a notch 8, of height h equal to the thickness e of the ribbon 3, extending transversely relative to the longitudinal axis of the parallelepipedal block 6a.
  • Each support 5 is obtained for example by molding, and is made of a light material, such as for example expanded foam.
  • each support 5 as shown in FIG. 2 is mounted transversely relative to the central strip 3, the underside of the parallelepipedal block 6a of each support 5 being fixed, for example by gluing , on the lower conductive plate 2a.
  • the conductive tape 3 is positioned in the notches 8 of the supports 5 so as to be held in place, and the upper conductive plate 2b is mounted to bear on the upper face of the rectangular block 6a of each support 5.
  • the two conductive plates 2a and 2b are made integral with one another by any suitable fixing system, constituted for example by rivets.
  • the lower and upper faces of the parallelepiped block 6a of each support 5 can be partially covered with a metal layer 9, made of zinc, formed for example by shooping, while the end face of the parallelepiped block 6a can be completely covered with this same metal layer 9, thus ensuring the electrical connection between the two conductive plates 2a and 2b.
  • each piece forming a support 10 is in the form of a parallelepipedic block 11 a comprising a tapered longitudinal extension 11b at the end of which is a notch 13, of height equal to the thickness e of the tape 3, and in which the conductive tape 3 is positioned so as to be held in place.
  • Each support 10 is obtained for example by molding, and is made of a hard material, such as for example fluorinated resin (teflon) or polyphenylene oxide.
  • the tapered portion 11b of each support 10 includes a recess 15 intended to avoid any disturbance of the electric field inside the triplate line.
  • each support 10 as shown in FIG. 3 is mounted transversely with respect to the conductive tape 3, the lower and upper faces of each parallelepipedal block 11a being supported on the conductive plates lower 2a and upper 2b, respectively.
  • the parallelepipedal block 11a of each support 10 has a hole or recess 17 formed over its entire height, and in which is engaged a metal spacer (not shown) ensuring the fixing of each support 10 with the two conductive plates 2a and 2b, as well as the electrical connection of these two plates.
  • the triple air line 1 In order to reduce the bulk in depth of the triple air line 1 which has just been described, it can be turned over or folded over one of the two conductive plates 2a or 2b.
  • the triplate line 1 is folded over its upper plate 2b by the curvature of its lower plate 2a and of its central strip 3, thus creating a superposition of two air triplate lines.
  • the curves of the lower plate 2a and of the central strip 3 are shown in C and in D, respectively.
  • FIG. 5 shows a discrete element of the power divider, the central strip 3 of which ends, for example, by two branches 20a and 20b each intended to supply power to a radiating source (not shown).
  • non-limiting examples will be the production of a radiating element, such as for example a half-wave dipole, and the production of a ring.
  • the conductive strips 22 and 23 of the two lines intended to be connected comprise two complementary recesses 25 and 26, obtained for example by chemical cutting, and formed on their respective ends.
  • the two ribbons 22 and 23 are fitted one inside the other, then are fixed to each other, for example by welding. It will be noted that this connection system by complementary steps allows the ribbons, once connected, to maintain good temperature resistance.
  • the applicant has produced a three-plate air line transmitting a power greater than 40 KW peak, and generating losses of the order of 0.2 dB / m in the “S” band.
