Definitions

  • the present invention relates to an elementary microwave antenna, that is to say an antenna which can either operate alone, or be one of the elements of an antenna array, or be used alone or in an array as a primary source of 'A reflector antenna system or focusing device, this antenna being able to operate with two orthogonal polarizations.
  • this third resonant element is in turn a selective element in polarization and shaped so as to be transparent for said first microwave wave and conversely so as to constitute a so-called "passive" radiator or resonator, of the "patch" type also, for said second microwave wave.
  • this antenna element is a transmission / reception microwave antenna element, this antenna element being capable of transmitting or receiving two microwave waves. distinct and whose polarizations, which are for example linear polarizations, are orthogonal.
  • this element antenna can, of course, operate alone, but it is more typically intended to be part of an antenna array comprising a greater or lesser number of antenna elements, of the same type or not.
  • This antenna element consists of a cavity 1, of circular section in this example, the bottom 2 and the circular side wall 3 are metallized. This cavity is completely open in the direction D of emission of the radiation, so that it constitutes a blind hole as seen in FIG. 1.
  • This cavity can be partially or entirely filled with dielectric material.
  • axis 8 between the probe 4 and the probe 6, is placed an obstacle 9, plane and orthogonal to the axis 8, which is shown in plan view in FIG. 2 and which is selective in polarization in this direction that it constitutes a short-circuit plane, orthogonal to axis 8, for the wave radiated or received by the upper probe 6, while it forms a circular obstacle plane, also called "radiating pad” or "patch", defining a non-looped radiating slot 10 consisting of at least two half-slots, here semicircular 10A, 10B, physically separated from each other and of the same radius, for the wave radiated or received by the lower probe 4.
  • the selective patch 9 has a planar, quasi-circular shape, with two diametrically opposite "ears" 11 and 12 which electrically connect the central disc 13 to the circular lateral wall 3 of the cavity 1. It constitutes by following a short circuit for the electric field E2, relating to the probe 6, which is directed along these ears 11 and 12, while it forms a quasi-circular patch for the electric field E1, orthogonal to the field E2 and relating to probe 4.
  • this patch 13 is provided a patch 15 which is selective in polarization in the sense that it is designed to be transparent for the electric field wave E1 relative to the probe 4, while it forms a real patch for the E2 wave relative to the probe 6.
  • this selective patch 15 consists of a set of parallel conducting wires 16 which are directed in the direction of the field E2.
  • the operation of this elementary antenna is as follows:
  • the selective member 9 is a short-circuit plane for the field wave E2 which is emitted or received by the upper probe 6.
  • the bottom of the cavity 1 is therefore constituted by this member 9.
  • the patch 13 constitutes a first patch, conventionally called “active”, while the member 15, which behaves like a patch, plays the role of the so-called “passive” patch, the essential role of which is to widen the bandwidth of the microwave signal emitted or received by this probe 6.
  • the field wave E1 which is emitted or received by the lower probe 4, the member 15 is completely transparent, and is therefore absent from the electrical point of view, while the member 9 plays the role of an "active" patch and that patch 13 is then, for this wave, a "passive" patch.
  • element 15 plays the same role with respect to elements 6 and 13 as element 13 with respect to elements 5 and 9.
  • this antenna element can transmit or receive two waves of orthogonal polarizations E1, E2 without these two waves, which are then completely dissociated from the electrical point of view, interfering with each other.
  • bandwidth waves which are sufficiently wide because, for each of them, the presence of a "passive" patch, respectively patch 13 for the E1 wave and patch 15 for the E2 wave.
  • this antenna element has good characteristics of mass and size due to the fact that it is in fact made up of two conventional antenna elements (cavity, active patch, and passive patch) which are physically " nested “one inside the other, in fact constituting a geometric multilayer structure at two different levels.
  • FIGS. 4 and 5 A practical example of embodiment of the antenna element which has just been described is shown in FIGS. 4 and 5, where the corresponding elements are designated by the same reference numbers.
  • the cavity 1 is produced in a dielectric body 17, the walls of which intended to be at ground potential are either metallized or coated with metallic layers 18.
  • the two aforementioned "ears" 11 and 12 are here made of two parallel metal wires, respectively 11A, 11B and 12A, 12B, which are welded to the central metal disc 9 on the one hand and to a metal ring 19 taken in the body of the body 17 on the other hand.
  • the members 13 and 15 are held in place by conventional insulating means and not shown.
  • the invention is not limited to the embodiment which has just been described.
  • the upper selective patch 15 could not be provided, so that the antenna part relating to the probe 6 (wave E2) would then not include a passive patch.
  • the antenna part relating to the probe 6 wave E2
  • the antenna part relating to the probe 6 wave E2
  • other models of supply or reception lines could be used.
  • the geometric shapes and reliefs of the cavity and its associated organs can be other than those shown here.
  • the cavity can be produced in a metal block.
  • patch 9 can be produced in any way, in particular the electrical contacts 11 and 12 between patch 9 and the walls of the cavity 1 can be provided in multiple ways.
  • different radiating elements can be used, such as elements radiating a single polarization, combined with bipolarization elements according to the invention.
  • This antenna can be used alone or in a network to illuminate a focusing system.
