Definitions

  • the invention relates to a multifrequency antenna, usable in particular in the field of space telecommunications.
  • each mission has its own specificities concerning the following characteristics: - Frequency band, - blanket, - general radio-electric performances (gain, decoupling of space etc ).
  • the object of the invention is to meet such an objective.
  • the invention proposes, for this purpose, a multifrequency antenna comprising a first printed antenna operating at one or more frequencies, characterized in that it comprises a second antenna disposed in front of the first antenna using the same radiating surface and operating at a different frequency .
  • the first antenna is formed of a ground plane, of a dielectric substrate on which is disposed a metal track and the second antenna is a wire type antenna which crosses the first antenna in a through hole drilled in the center of symmetry of the metal track, the ground plane seen by the wire antenna being composed of the metal track as well as the ground plane general of the printed antenna.
  • the first antenna is a planar antenna
  • the second antenna is produced by a coaxial cable which ends in a dipole.
  • the first antenna is a planar antenna and the second antenna is produced by a coaxial cable which ends in a helix.
  • the invention consists of the association on the same projected surface of at least two radiating elements operating according to different principles: - radiation produced by "cavities”, thus producing a microstrip or printed type antenna ("Patch” in English) - wire-type radiation, thus producing a radiating dipole or helix.
  • a dual-frequency antenna according to the invention enables radiation on one frequency to be produced at one frequency using a printed antenna, radiation at another frequency via a wire antenna.
  • the independence of operation of these two antennas makes it possible to optimize them at separate frequencies.
  • the decoupling between the two elements is ensured by the fact that the principles which contribute to the radiation are of different natures.
  • a wire antenna is installed on a printed antenna using this property.
  • Such an embodiment has the following two characteristics: -
  • the wire antenna does not affect the adaptation and radiation characteristics of the printed antenna. - Due to different radiation principles, the coupling between the two elements remains very weak.
  • wire antenna A certain number of types of wire antenna can be envisaged as being able to be mounted on the printed antenna. The precise choice depends on an optimization in relation to a need, and directs the solution towards dipoles, monofilar helices, quadrifilar helices ...
  • wire-type antennas have been studied for many years (see notably Richard C manual JOHNSON and Henry JASIK entitled “Antenna Engineering Handbook", McGraw-Hill Book Company, New York).
  • the calculation methods developed in particular in this document make assumptions about the nature of the current established on the conductors in order to assess the radiation integral.
  • the wire element In nominal operation (without printed antenna) the wire element is placed in front of a ground plane at a suitable distance.
  • the resulting radiation can be estimated for example using the principle images for a dipole structure.
  • the ground plane seen by the wire antenna being produced by all of the printed conductor and the general ground plane of the antenna printed.
  • the operating frequency of the wire antenna does not correspond to a resonance of the printed antenna, the printed antenna does not play a particular role (field concentration, cavity, resonance).
  • a slight adaptation of the height of the dipole may however be necessary in order to optimize the resulting diagram.
  • FIG. 3 we have: - A flat printed antenna, as shown in Figure 2, pierced in its center with a through hole 15; - a coaxial cable 16, passing through this hole 15 perpendicular to the plane of the printed antenna. This cable ends at its free end with a dipole antenna 17.
  • the dielectric substrate has a thickness of a few millimeters, the track is square in shape and about 60 mm on a side.
  • the printed antenna has a resonant frequency at 1628 MHz (see curve 20 in Figure 5) and adaptation bandwidths: at -10dB: 31 MHz at -15dB: 16 MHz.
  • the dipole alone is defined at 2449 MHz (see curve 21 in Figure 6) and has the following adaptation bandwidths: at -10dB: 227 MHz at -15dB: 110 MHz
  • the tuning frequency is obtained for 1638 MHz (see curve 22 in Figure 5), ie a deviation of less than 1% compared to the "Patch" alone, and the adaptation bandwidths are : at -10dB: 31.5 MHz at -15dB: 16.9 MHz - for dipole antenna access, the tuning frequency obtained is 2446 MHz (see curve 23 in Figure 6), i.e. a deviation much less than 1% compared to the element alone, the adaptation widths are: at -10dB: 236 MHz at -15dB: 122 MHz
  • the thickness of the dielectric substrate is relatively small and depends on the nature of the dielectric material; for a "honeycomb" structure in KEVLAR: we will always have a thickness ⁇ 10 mm, for dielectric materials with a higher constant, this thickness may not exceed a few millimeters (2 to 3 mm typically for ⁇ r ⁇ 2, 5)
  • the coaxial cable 16 passing through the hole 15 ends in an antenna 18 in a helix.
  • the shape of the microstrip antenna may obviously not be planar and be provided with a certain curvature (cylindrical, spherical%), Depending on its particular location on a structure: for example implantation on concave surfaces.
