Definitions
- the invention relates to a system for transmitting electrical energy, at microwave frequencies, with a gyromagnetic effect, such as a circulator, insulator or filter, of the type comprising a gyrator device which comprises at least one tablet, advantageously in the form of a disc, in a gyromagnetic material such as ferrite material, one face of which is set to a reference potential such as a metallic plane which may or may not be connected to the ground of the system and at least two tuning networks each comprising an inductance arranged on the other side of said patch and one end of which is grounded to the gyrator device while the other is connected to an input terminal of the transmission system, the gyrator device being subjected to a homogeneous magnetostatic field of excitation of the gyrator.
- a gyromagnetic effect such as a circulator, insulator or filter
- the present invention aims to propose a transmission system of the type stated above, which at least makes it possible to greatly reduce this parasitic capacity so as to increase the natural frequency and that the other parameters of the system such as the geometric dimensions of the gyrator device , the number of conductive strands of the inductors and the coupling coefficient can be advantageously chosen without this being detrimental to the natural resonant frequency.
- a transmission system according to the invention is characterized in that a layer made of an electrically insulating material and of low permittivity is disposed between the inductors and the chip made of gyromagnetic material.
- the insulating layer is formed by superposition of several plates of an electrically insulating material of low permittivity, which are interposed between the aforementioned inductors by electrically insulating the inductors from each other.
- an aforementioned inductance is produced in the form of a number of conductive strands connected at one end to the ground of the gyrating device and mounted in parallel, such as a number between 2 to 10 .
- Figure 1 is a perspective and exploded view of an electrical energy transmission system according to the present invention.
- Figure 2 is a sectional view along a vertical plane passing through the line II-II of Figure 1, in the assembled state and on a larger scale.
- FIG. 3 is a perspective and exploded view of a first embodiment of the gyrator device 1 according to FIG. 1.
- FIG. 4 is a perspective and exploded view of a second embodiment of the gyrator device 1 of FIG. 1.
- FIG. 5 is a third embodiment of the gyrator device according to FIG. 1.
- FIGS. 6 and 7 represent curves defining the relationship respectively between the limit frequency on the one hand and the admissible power and on the other hand, the diameter of the gyromagnetic pellet.
- an electrical energy transmission system, microwave, gyromagnetic effect essentially comprises a gyrator device 1 capable of being mounted on a printed circuit board 2 disposed between plates upper and lower respectively 3 and 4 made of metal or a non-magnetic alloy, for example aluminum, each provided with a central bore 5 intended to receive a pole piece 7 for example of steel and a magnet 8.
- An upper magnetic closure plate 10 and a lower magnetic closure plate 11 are disposed respectively on the free outer surfaces of the upper and lower magnets 8.
- the assembly is surrounded by a belt 12 consisting of several elements 13, 14, 15 and magnetically connecting the plates upper and lower closure 10 and 11 to close the magnetic circuit.
- the belt has three connectors 16 which are fixed to three sides of the plates 3 and 4 in the assembled state of the system.
- the printed circuit board 2 has in its center a recess 17 adapted to receive the gyrator device 1.
- the board 2 carries on its upper surface a pattern of bands and electrically conductive zones, namely three substantially radial bands 19 which extend from the edge of the recess 17 to the edge of the plate and are intended to be electrically connected each to the conductor 18 ( Figure 2) of one of the connectors 16, and three zones 20 which are electrically isolated at 21 from the strips 19 and are intended to be in electrical contact with the upper plate 3 which bears on each zone 20 by a pin 22 and constitutes a ground electrode.
- each strip 19 is generally connected to the corresponding conductor 18 via an adapter network, not shown, and comprising LC type cells, in a manner known per se.
- FIGS. 3 to 5 three embodiments of a gyrator device 1 according to the present invention will be described below.
- the gyrator device 1 comprises a configuration of three inductors 23, 24, 25 each comprising two conducting strands 27, 28 arranged in the same plane which are parallel and connected at their indicated ends at 29 and 30. These ends are produced in the form of electrical connection lugs, one of which, for example the lug 29 is connected to one of the earth zones 20 of the printed circuit on the wafer 2 and of the gyrator device while the other tab bearing the reference 30 will be electrically connected to one of the conductive strips 19 of the printed circuit.
- These inductors 23 to 25 can be made of any suitable conductive metal and have a self-supporting structure. The inductors are electrically isolated from each other by interposition an appropriate insulator. The inductors are arranged so as to be angularly offset by 120 °.
- Two discs 32, 33 of circular shape in the example shown, made of an electrically insulating material and of low permittivity are arranged on either side of the configuration of the three inductors 23 to 25. These discs could be discs Teflon or a dielectric material such as ceramic. On each disc 32, 33 is placed a disc respectively 34, 35 of a gyromagnetic material, such as ferrite material. The external face of each gyromagnetic disc is therefore, in the assembled state of the system, in contact with a metallic plane which may or may not be connected to the ground of the system. As can be seen from FIG. 1, the various connection tabs 29, 30 project radially from the assembly formed by the stack of disks 32 to 35 on the central configuration of the inductors 24, 25, in order to be able to be electrically connected to the circuit printed brochure 2.
- FIG. 4 shows an embodiment of the gyrator device 1 in which the insulating layer, of low permittivity is formed by four discs or plates of thinner thickness 37 to 40 which are stacked between the upper and lower gyromagnetic discs 34, 35.
- three inductors 23 to 25 are each arranged between two neighboring insulating discs, being angularly offset by 120 °, as shown in FIG. 3.
- each inductor has ten parallel strands.
- Each inductor can be made so as to present a self-supporting structure or be laid, in the form of a printed circuit on a surface of one of the discs 37 to 40, of course providing a support for the connecting lugs 29, 30.
- the discs 37 to 40 are advantageously made made of a dielectric material such as ceramic.
- the insulating layer of low permittivity is formed by seven disks 42 to 48 which are stacked between the gyromagnetic disks 34, 35 while sandwiching the inductances therebetween.
- each inductor is divided into two halves which, in the whole of the gyrator are juxtaposed and electrically connected in parallel.
- the inductance 23 of FIGS. 3 and 4 is now formed by the two half-inductors 23a and 23b, interposed respectively between the disks 43, 44 and 46, 47, that is to say between two pairs of different disks .
- the inductors 24 and 25 are respectively formed by the half-inductors 24a, 24b and 25a, 25b and arranged between two pairs of different discs, as shown in FIG. 5.
- the general structure of such a transmission system is known per se and therefore does not need to be described in more detail.
- the discs made of a gyromagnetic material 34, 35 are immersed in the static magnetic field generated by the magnets 8, as is clear from FIGS. 1 and 2.
- the magnetic circuit is closed by the plates of upper 10 and lower 11 closure and the belt 12.
- Via the connectors 16 a perpendicular microwave field is applied to the gyromagnetic material, the wavelength of this field being very large compared to the length of the axes of the gyromagnetic discs, so that the field is uniform in the volume of these.
- the natural frequency that is to say the operation of the gyrator device 1
- This operating frequency constitutes the limit frequency of the system.
- the frequency to which the system will be granted is determined by the paralleling on each input or access of the gyrator device 1 of a capacity (not shown) and the relative bandwidth as well as the resistance can be modified by means of LC type cells inserted at the input of the gyrating device.
- a capacitor C ⁇ is introduced which can be written in the form: C ⁇ : ⁇ o ⁇ ⁇ r ⁇ S e where ⁇ o , ⁇ r , e and S denote respectively the permittivity of the vacuum, the relative permittivity of the insulator, the thickness and the surface of the insulating layer.
- each Teflon disc could have a thickness of 0.1 mm, which gives a total thickness of the insulation of 0.7 mm.
- the maximum thickness is a function of the thickness of the gyromagnetic discs and is roughly determined by the term where H is the thickness of the gyromagnetic disc.
- the limit frequency F of a gyrator according to the invention is multiplied by ⁇ K compared to a conventional gyrator if K is the coefficient by which the parasitic capacity has been reduced by providing the insulating layers of low permittivity , as just described.
- insulator of low permittivity and relatively high thickness of 1 to several tenths of a millimeter also makes it possible to increase the dimensions of the discs of gyromagnetic material and the number of strands constituting the inductors and thus improve the coefficient of coupling.
- the admissible power can be multiplied by two or three taking into account the lower thermal resistance, the larger heat exchange surfaces and a better distribution of energy inside the gyromagnetic material. Thanks to the measures which have just been indicated, it is possible to reduce the losses and increase the relative frequency band.
- Figures 6 and 7 which respectively show the limit frequency F (in MHz) and the admissible power Pa (in Watts), as a function of the diameter D of the disc made of gyromagnetic material, such as ferrite material, (in cm) confirm what has just been said.
- curve A gives the values of a typical system of the classical technique
- curve B gives the values which have been measured, under the same conditions as for curve A, of a system according to the invention, that is to say comprising an insulator of low permittivity and of a high thickness between the configuration of the inductors and the gyromagnetic ferrite discs.
- the relative pass frequency bands of a system according to the invention can have a width which is twice that of a known system in the low frequency zone of 30 MHz.
- the layer added to reduce the parasitic capacity can be an insulator of the adhesive type or not, a dielectric such as ceramic of low permittivity, or the like.
- the printed circuits can be simple or double-sided or of the multilayer type.
- the shape of the pellets of gyromagnetic material can have any other known suitable shape. It is the same with regard to the insulating layer 8 and the inductors. The number of pads and insulating layers may vary.
- the invention is also applicable to a system structure using only one gyromagnetic pad on which the configuration of the inductors will be placed, with interposition at least one insulating layer of low permittivity.
- the number of access fittings can be different and vary between two and a higher number.
