Definitions

  • the present invention relates to a slot type microwave device made on a metallized substrate.
  • the present invention also relates to slit type antennas using such a structure.
  • the photonic bandgap structures known by the abbreviation BIP or generally by the term "photonic band gap structure” in the English language are periodic structures that prohibit the propagation of a wave for certain frequency bands. These structures were first used in the optical field, but in recent years their application has spread to other frequency ranges. Thus, they are used in particular in microwave devices such as antennas, filters, guides, etc.
  • the use of a photonic band gap structure with a line made using microstrip technology is described in particular in the article "Novel 2-D photonic band gap structure for microstrip lines” published in the IEEE journal “Microwave and guided wave letters - Vol. 8 - No. 2 - February 1998 » XP000730352.
  • This article describes a forbidden photonic band structure constituted by discs etched on the face of the substrate opposite to that receiving the microstrip line. This structure makes it possible to produce a filter.
  • Other examples are disclosed in WO 01/95434 and in the article of Yeo et al "Design of a Wideband Antenna Package with a compact Spatial Notch Fitter ", p. 492-495, IEEE Antennas and Propagation Symposium 2002 , XP 10591744.
  • the BIP structures are obtained mainly by engraving periodic patterns obtained by de-metallization of the ground plane of the structure produced by microstrip technology as described above, or by periodically piercing the substrate comprising the microstrip technology circuits while maintaining the continuity of the ground plane.
  • the structures already described in the prior art have great potential, including filtering.
  • the present invention therefore aims to propose the application of the production of a novel photonic bandgap structure on a microwave device in the antennas, in particular antennas of the annular slot type or Vivaldi type antennas to realize a filtering or frequency adaptation of said antenna.
  • the present invention relates to a microwave device as claimed in claim 1.
  • the periodicity between two patterns is equal to k ⁇ g / 2 where ⁇ g is the guided wavelength in the slot at the frequency of the selected forbidden band and k an odd integer.
  • the width and depth of the band gap are a function of the surface of the periodic pattern.
  • a periodic pattern has the form of a disk, which can be repeated periodically and whose area will determine the width and depth of the bandgap.
  • the periodic patterns are different patterns having the same equivalent area, namely for a disc-shaped pattern, the ratio r / a in which r is the radius and the distance between two patterns is identical while along the structure.
  • the periodic pattern is produced by etching a metal layer deposited on the face of the substrate opposite to the face receiving the slot.
  • the periodic patterns are made at least partially under the slot.
  • the present invention also relates to microwave antennas in which a BIP structure is formed to obtain a filtering of certain undesirable frequencies or to obtain several communication bands by opening forbidden bands on the frequency response of a very wide band antenna.
  • This type of antenna is particularly interesting in the field of wireless telecommunications.
  • the subject of the present invention is therefore a microwave antenna constituted by an annular slot according to claim 5.
  • the periodicity of the patterns of the BIP structure is chosen so that the frequency of the forbidden band is equal to one. harmonics of the operating frequency of the annular slot.
  • the periodicity of the patterns of the BIP structure is chosen so that the frequency of the forbidden band is greater than the operating frequency of the annular slot.
  • the structure is used in its bandwidth, which makes it possible to make the circuits using slots more compact.
  • the slot is fed in a line-slot transition by a feed line made in microstrip technology.
  • a photonic bandgap structure is formed by de-metallizing the surface of the substrate opposite the surface on which the microstrip line is made.
  • the band structure prohibited is performed along at least one of the profiles of the slot forming the antenna type Vivaldi.
  • the Vivaldi-type antenna is fed with a line-slot transition via a feed line produced using microstrip technology. It is then possible to increase the number of forbidden bands, either by adding under the microstrip line, a photonic bandgap structure by de-metallizing the surface of the substrate receiving the line, or by arranging two forbidden photonic band sizing. distinct, one on the first profile of the Vivaldi type antenna, corresponding to a first frequency band to be prohibited, and the other on the other profile of the Vivaldi type antenna, corresponding to a second band of frequency to be prohibited.
  • the device is a printed circuit provided with a line-slot. More specifically, the device comprises a substrate 1, a face 2 of which has been metallized and in which a line-slot 3 is produced by etching the metal layer 2. As shown in FIG. figure 1 the substrate has a height h, and is made of a known dielectric material.
  • the BIP structure is obtained by producing patterns 4 periodically on the face of the substrate 1 opposite the face carrying the metal layer 2.
  • the patterns 4 are made by etching a metal layer giving the metal patterns 4.
  • the patterns 4 are etched under the line-slot 3.
  • the patterns 4 are spaced a distance a which gives the repetition period of the pattern, this distance fixing the center frequency of the bandgap when the patterns are identical.
  • the distance "a" is of the order of k ⁇ g / 2 where ⁇ g is the guided wavelength in slot 3 at the central frequency of the chosen forbidden band and k an integer.
  • the pattern is of any shape. However, the equivalent area of the pattern determines the width or depth of the band gap.
  • the patterns used may be disk-shaped patterns 4a, as shown in FIG. figure 2a , rectangle or square 4b, as shown on the figure 2b , of a shape substantially in H for playing on several parameters such as the dimensions L1, L2 and g, namely a shape with 3 degrees of freedom, as represented by the pattern 4c on the Figure 2c or of annular form 4d, as shown in the figure 2d .
  • the dimensions of the pattern in particular its equivalent surface, make it possible to adjust the width or depth of the bandgap.
  • a structure according to the present invention can be obtained by using disc-shaped patterns whose radius is variable, in a progressive manner, while maintaining a spacing between disks constant and equal to a.
  • the variation can follow a defined mathematical law such as a Hamming, Barlett or Kaiser window type law.
  • the spacing between the discs can also be changed gradually.
  • the structures described above can be combined, in particular to obtain an enlargement of the band gap.
  • the center frequency corresponds to the center of the frequency band defined by the minimum frequency of the BIP structure having the lowest center frequency and the maximum frequency of the BIP structure having the highest center frequency.
  • the slit-line was simulated as being excited by two line-slot transitions 12 and 13 at each end of the slot 10.
  • the results of the simulation represented on the figure 5a allow to highlight the opening of a forbidden band having a width of about 1 GHz around the frequency 6.5 GHz.
  • a BIP structure was realized under a closed slot type antenna, fed by a feed line, more particularly a line of the microstrip line type, according to a line-slot transition using Knorr's known laws.
  • annular slot 20 is represented. This slot was made by etching a ground plane on a substrate, not shown. This annular slot 20 is fed by a microstrip line 21, the assembly being dimensioned in known manner for operation at a given frequency F0. In this case, the antenna has resonances at all the odd multiples of the frequency F0.
  • a BIP structure formed by disks 22 metallized periodically under the annular slot has been realized.
  • This BIP structure 22 is dimensioned so as to filter one of the harmonics obtained in the case of an annular slot antenna of conventional type.
  • the periodicity a between two patterns 22 has been calculated so as to have a frequency of the forbidden band corresponding, for example, to the harmonic of order 3.
  • a BIP structure of the same type can be used in its bandwidth.
  • the BIP structure is dimensioned to present a band gap at a frequency higher than the desired frequency of use.
  • the BIP structure is at the origin of an effect called "slow wave”: the phase of the transmission coefficient of a wave along a slot line is modified by the presence of the metal pellets under this line. The speed of propagation of the wave under the slot is then slowed down ("Slow-wave effect"). It is therefore possible to propose a BIP structure in which the equivalent electric length of the slot is modified.
  • the presence of the BIP structure makes it possible to reduce the guided wavelength in the slot: ⁇ boy Wut BEEP ⁇ ⁇ boy Wut ⁇ ⁇ 0
  • annular slot antenna sized at 2.4 GHz has identical operation in the presence of a BIP structure but at a lower frequency (2 GHz, for example).
  • the shape of the patterns 22a and 22b of the BIP structure may be different, for example circular or square.
  • the curve 12b if the surface of the pattern 22a and the pattern 22b is equivalent and the spacing a between two patterns is identical, substantially identical phenomena will be obtained, notably the suppression of the harmonic of rank 3 obtained with an annular slot antenna of conventional type, when the BIP structure operates as a filter.
  • the use of a BIP structure under a slot-type antenna to suppress the frequency of an odd harmonic may result in the creation of additional harmonics around the double frequency (This is represented by a low-amplitude peak around 4 GHz).
  • patterns 23 are created under the supply line 21 made in microstrip technology, by de-metallization of the ground plane below the microstrip line.
  • slots are open in the ground plane below the micro-ribbon line.
  • a Vivaldi type antenna 31 was made by opening a slot de-metallizing the surface 30, this slot having an outwardly flaring profile.
  • This Vivaldi type antenna is well known to those skilled in the art and will not be described in more detail.
  • this antenna is fed by a feed line 34 according to the Knorr principle.
  • This supply line 34 is constituted by a microstrip line.
  • a BIP structure constituted by a periodic pattern has been etched on the face of the substrate opposite the face receiving the flared slot 31, along at least one of the profiles constituting the Vivaldi type antenna.
  • the BIP structure consists of four disks 32 regularly spaced a distance a.
  • a BIP structure as represented on the figure 15 allows to create, in a Vivaldi type antenna, frequency bands in which the wave propagation is forbidden. Indeed, the Vivaldi antenna has intrinsic operation at a very wide frequency band, and the use of a BIP structure will create one or more operating subbands.
  • a Vivaldi antenna without a BIP structure has a 10 dB bandwidth of 2 GHz between 5.5 and 7.5 GHz.
  • the operating band of the Vivaldi type antenna is reduced by adding the BIP structure which prohibits the propagation of waves along the slot, between 5.5 and 7 GHz.
  • a BIP structure profile 32a, 32b, as shown in FIG. figure 17a can be used.
  • the filtering can be reinforced by supplying the Vivaldi antenna with a power supply line 34 provided with a conventional BIP 33 structure, as described above in the case of an antenna of the type with annular slot.
