Definitions

  • the present invention relates to a wire antenna for HF transmission by an underwater vehicle.
  • this type of antenna has a coaxial cable and a radiating end element.
  • This assembly is then for example towed by the underwater vehicle and drags behind it.
  • the antennas known in the state of the art have a certain number of drawbacks, in particular at the level of their very limited performance due to the impedance mismatch of this antenna, which results in reduced transmission efficiency.
  • the aim of the invention is therefore to resolve these problems.
  • the subject of the invention is a wire antenna for HF transmission by an underwater vehicle according to claim 1.
  • these figures illustrate a wire antenna for HF transmission by an underwater vehicle such as a submarine proper.
  • the antenna is designated by the general reference 1.
  • this antenna then comprises a coaxial cable designated by the general reference 2 and a radiating end element designated by the general reference 3.
  • This antenna is then towed behind an underwater vehicle such as a submarine proper and rises to the surface of the water (at the “diopter”) to allow data exchange and in particular HF emissions.
  • An intermediate electrode is placed between the two parts of this antenna 1, namely between the coaxial cable 2 and the radiating end element 3.
  • This intermediate electrode being designated by the general reference 4 on the figures 1 and 2 .
  • the end of the radiating end element 3 also has a terminal electrode 5.
  • the radiating end element also consists of a single-stranded member.
  • this element is formed by a multistrand member.
  • This multi-stranded member is formed by a support member which can also be called a core, at the periphery of which are distributed several radiating conductors carried by this support member and ensuring the exchanges.
  • the portion of coaxial cable 2 thus constitutes an offset cable towed behind the underwater vehicle.
  • the intermediate electrode 4 then provides the electrical interface between the conductive core of the coaxial cable 2 and the conductors of the stranded end of the element 3 of this antenna, as well as a possible recovery of a braid in the sea. of this coaxial cable.
  • the terminal electrode 5 conventionally enables the radiating element to be terminated.
  • Such a structure has a number of advantages over antenna systems of the state of the art.
  • the buoyancy of the multi-strand antenna end of the wire antenna according to the invention is greater than that of a single-strand configuration of the coaxial type, due to a lower weight.
  • This definition is essential for the envisaged application because transmission in HF band is only possible with an antenna perfectly on the dioptre, that is to say on the surface of the water.
  • the attenuation of the HF signal when passing through this diopter is such that a slightly submerged antenna does not function correctly in transmission.
  • the four radiating conductors for example from the multi-strand radiating end, are arranged at the periphery of a member such as a support cable or the like, making it possible to retain them.
  • the dimension characteristics such as the length of the various portions of the antenna for example make it possible to define, for example, a passband of the wire antenna in HF band, for example on the basis of a transmission in ⁇ / 4 at the frequency of 2 megahertz ie the bottom of the HF band.
  • the radiating end is made up, for example, of four regularly distributed conductors.
  • the conductors placed in short circuit or not are connected at the level of the terminal electrode by an operation, for example mechanical.
