Definitions

  • Directive antennas comprising a two-wire line about which a helix-shaped metal conductor is wound.
  • the antenna according to the invention presents the following remarkable features:
  • the antenna is excited by a transmission line, the outer conductor of which constitutes one of the elements of the antenna itself, coupling means being provided between this transmission line and the remainder of the antenna.
  • the antenna comprises a reflector through which extends the transmission line.
  • the antenna comprises of a two-wire line, comprising elements 1 and 2.
  • This line is surrounded by a metal helix 3.
  • Element 1 is the external conductor of a coaxial line, which is excited at one end by a source 7.
  • the inner conductor 6 terminates at the opposite end by a junction element 5, which is, for example, welded to element 2.
  • the coaxial line 1-6 extends through a reflector 4 and oscillator 7 is positioned at the other side thereof.
  • the operation of the antenna is as follows:
  • Oscillator 7 feeds, through the coaxial line 1-6, the junction element 5 which excites the two-wire line 1-2.
  • the antenna may also operate as a receiver antenna.
  • a directive antenna comprising: a two-wire line including two wires; a helix wound around said line; a coaxial line having an outer and an inner conductor and two ends, said outer conductor serving as one of said wires; an ultra-high frequency source coupled to one of said ends; and means coupling said inner conductor to the other wire.
  • a directive antenna comprising: a two-wire line including two wires; a helix wound around said line; a coaxial line having an outer and an inner conductor and two ends; said outer conductor serving as one of said wires; an ultra-high frequency source coupled to one of said ends; means coupling said inner conductor to the other wire; and a reflector positioned at said one end.
