Definitions

  • v 50 volts, a voltage of 10,000 volts.
  • Such voltage values impose very high insulation between the different wires either from the same network of a phase-shifting panel or between the wires of the networks of adjacent phase-shifting panels or between the control wires outside the phase-shifting panels.
  • this diode wire forming part of the networks of metallic wires constituting the phase-shifting panels which are the subject of French patents 2 063 967 and 2 224 887.
  • This process allows a supply without the introduction of additional control wires, makes it possible to simultaneously supply all the diodes of '' a single wire and does not require the use of very high supply voltages disturbing for the diodes as well as for the control circuit external to the phase shift panel, and which moreover makes it possible to increase the width of the frequency band of waves of use of the panel and allows a better control of the value of the differential phase shift between the two states of the phase shift panel according to that the wires with dio arrays of diode wires are electrically continuous or sectioned.
  • the improvement of the electronic scanning method according to the invention consists in constituting a network of parallel conductive wires carrying diodes intended, depending on their condition, to make these wires continuous or cut and of continuous metal wires, parallel to the wires carrying diodes and located on either side of the diode wire, at the same distance from it, each of the diode wires thus being associated with two continuous wires which are used for food ter groups of diodes of this diode wire, on each of the conducting wires carrying diodes being mounted a group of diodes in series, then another group of the same number of diodes, also in series but inverted with respect to the preceding ones, and create between the two continuous conductive wires which surround the diode wire conductive bridges between each point of the diode wire located between two groups of diodes of different directions and alternatively the continuous wire located on one side then on the other side of the wire diodes, so that each group of diodes in series is supplied by the voltage, to which is carried one of the two continuous son fram
  • the two continuous metallic wires (6) and (7) which frame the wire (3) are 8 mm on either side of ci, the diameter of the wires (6) and (7) is 0.22 mm.
  • Conductive strands (9) of 0.22 mm in diameter connect the points of the wire (3) located at the start of a group of diodes of the same direction to the wire (6) identical conductive strands connect the joints of the wire (3) located at the end of these same groups of diodes on the wire (7).
  • One end of the wire (6) outside the panel is connected at will to a voltage source of 500 volts, the end of the associated wire (7) being simultaneously brought to zero voltage. Therefore all the diodes (4) and (5). Are supplied in reverse under the average unit voltage of 50 volts necessary for their blocking.
  • the wire (3) becomes discontinuous and cut into sections of identical unit length defined by the pitch of the diodes (a).
  • the wire (6) is brought to a zero voltage and the wire (7) to a voltage of 5 volts. All the diodes (4) and (5) of the wire (1) are then supplied directly.
  • the wire (3) is continuous and traversed by a current of two milli-amps.
  • the panel thus formed is suitable for the transmission of waves of 3000 megahertz frequency, when the diodes on both sides of the panel are in the same state.
  • the differential phase shift due to the panel crossing by the 3000 MHz microwave wave with polarization parallel to the arrays of wires, for the two states of the diodes is 42 degrees and the attenuation is less than 0.12 decibel.
  • the external connections to the phase shift panel concerned can be grouped on the same side of this panel.
  • the voltage supply wires of the diode groups are integrated into the panel and also have a microwave function improving the possibilities of adaptation of the panel in a larger frequency band.
  • the subject of the invention is also the applications of the improvement according to the invention and of networks of metal wires enabling it to be applied to the power supply of the diode lines of the various panels constituting active lenses allowing electronic scanning of a microwave beam. in the perpendicular plane networks of wires.
