Definitions

  • the present invention relates to a plate type antenna for transmit and receive waves of wavelength ⁇ belonging to the band of frequency ranging from 100 Mhz to 6 Ghz and presenting in particular excellent transmission and reception characteristics in the 3.5 Ghz bands, the C band and the S. band
  • Plate antennas are well known. They are most often constituted by a first metal plate forming a ground plane and by one or more other metal plates arranged opposite the ground plane and which constitute the radiating plates. Most often, these two systems of metal plates are attached to opposite sides of a block of material the dielectric thus also ensuring the mechanical connection between the ground plane and the radiating plate (s).
  • An object of the present invention is to provide a plate antenna using as dielectric material the air while avoiding the disadvantages mentioned above, in particular with regard to the mechanical structure of the antenna.
  • a plate antenna which can comprise one or more plates radiant which uses air as dielectric and which presents a structure suitable mechanics since the mechanical connection is made by through the insulating plates that serve as supports.
  • the presence recesses in the plate surrounding at least a part of the metallizations forming the radiating plate (s) can effectively use the air as dielectric in the zone of maximum electronic field produced by the periphery of the radiating metallization (s). We thus obtain a optimal operation of the antenna.
  • the second insulating plate of the antenna is provided with a plurality of second metallizations of substantially rectangular shape and the metallizations are electrically connected by connecting portions.
  • the antenna comprises a first plate of insulating material 10 of the type used for the manufacture of printed circuits and whose thickness is preferably between 0.8 and 1.6 millimeters in order to have mechanical properties sufficient.
  • This metallization 12 has a generally rectangular shape.
  • the antenna also comprises a second insulating plate 14 made with the same insulating material that the plate 10 and whose thickness e is of the same order of than that of the plate 10.
  • a metallization by any suitable technique 16 constituting the radiating plate of, the antenna (patch in Anglo-Saxon).
  • metallization 16 has also a rectangular shape whose dimensions are adapted to the band frequency in which the antenna works. Spacers such as 18 and 20 fixed in the parts of insulating plates 10 and 14 devoid of metallizations ensure a rigorous positioning of the two insulating plates and therefore the plane 12 and the radiating plate 18.
  • the antenna is completed by a line 22 which is connected respectively to the radiating plate 16 and the mass plan 12 as is well known.
  • the insulating plate 14 is provided with recesses such as 24 and 26 arranged in a peripheral zone surrounding the portion of the insulating plate 14 covered by the metallization 16 for reasons that will be explained in connection with Figure 2.
  • the radiating part of the antenna is consisting of two metallizations respectively referenced 34 and 36.
  • these two metallizations are substantially of square shape and their dimension corresponds to ⁇ / 2, where ⁇ is the wavelength in which the antenna works
  • ⁇ is the wavelength in which the antenna works
  • These two metallizations 34 and 36 are electrically connected to one another by a electrical connection portion 38 ensuring the electrical continuity between the metallizations 34 and 36. It is defined around metallizations 34 and 36, as well as each side of the connecting portion 38 a so-called peripheral zone 40 whose width h is substantially equal to ⁇ / 10. It's inside this area device 40 that are formed the recesses such as 24 and 26.
  • the recesses must occupy the highest possible percentage of the area device 40 while nevertheless ensuring a sufficient mechanical connection between the portions of the insulating plate 14 on which the metallizations are made and the rest of this plate on which are fixed the spacers 18 and 20.
  • the material constituting the insulating plate must be removed where the amplitude electromagnetic field is maximum.
  • FIG. 5 shows an alternative embodiment of the recesses inside the peripheral zone 40.
  • the metallization 34 and the primer of the electrical connection portion 38 In the parts of the peripheral zone 40 corresponding to the electromagnetic field maximum, we find recesses for example circular, 54 which are very close together while on the other two edges of the plate, found recesses 56 also circular more spaced from each other in such a way that overall, one obtains the ad hoc mechanical resistance.
  • the radiating plates are rectangular or square. It goes without saying, however, that we would not go out of the invention if these metallizations were in the form of a circle, polygon, etc.
