Definitions
- the present invention relates to a polarization monolithic antenna crossed, especially for cell phones.
- Document FR-A-2 766 626 discloses a cross-polarized antenna having dipoles mounted on a reflector, being two by two orthogonal and thus defining at least one polarizing radiating cell cross.
- This antenna preferably comprises several radiating cells with crossed polarization, which are identical to one another and arranged on the same alignment along the reflector.
- each of the dipoles are identical. They have the shape of a Vé and are mounted back to back, the bases of Vés being in opposite. Each of them presents a solidarized jamb to the reflector and provided with two end lateral arms opposite the reflector. he is advantageously made of a single piece in the form of a plate cut properly and then folded in Vee.
- two dipoles are arranged orthogonally to each other by having the two conductive elements of one of them interposed between the two conductive elements of the other dipole, for so define one of the radially cross-polarized cells that constitutes a compact and robust radiating module.
- This known antenna also includes a power supply system for its radiating cells with cross polarization.
- This power system is double for feeding the two cell dipoles from two sources external energy. It is constituted in the same way whatever the dipole of each of the cells. It has a first section of coaxial cable connected to a coaxial connector for connection to one of the sources, seconds sections of coaxial cable each connected to one of the dipoles of the cells and a power divider coupling the first section to the second sections of coaxial cable.
- the present invention aims to minimize the disadvantages and to simplify the power system of a polarized cell antenna compact cross as mentioned above, and as a consequence to simplify the structure of the antenna by reducing its cost considerably.
- a monolithic antenna with crossed polarization having a substantially rectangular reflector, cells radially mounted on said reflector and each formed by two orthogonal dipoles, and a power system connecting the two dipoles of said radiating cells with two external energy sources, each of the dipoles comprising two V-shaped flat conductive elements, arranged back to back and each having a central folding leg attached to the reflector by a first end portion of said branch and two terminal lateral arms protruding from one side to another on a second end part of said branch, the two conductive elements of one of the dipoles of each of the cells being arranged each between those of the other dipole of the same cell, characterized in that said circuit power supply comprises two flat conductive power lines, mounted opposite said reflector and connected to one and the other of said sources respectively, and in that only one of the first two conductive elements each of said dipoles comprises a folded conductive tab, having a first end secured to the second end portion of the branch center of said first conductive element, extending inside the Ve
- the antenna comprises several identical cross-polarized radiating cells 1 which are mounted in being aligned axially on a reflector 2. These cells are in number four in the example shown but their number could be different.
- the reflector 2 is plane with two longitudinal rebounds 3 and 4 folded at 90 ° of the same side as radiating cells 1.
- each radiating cell 1 has two dipoles 11 and 12 orthogonal.
- Each of the dipoles is formed by a pair of conductive elements 11A and 11B or 12A and 12B having the shape a VE, whose Vés are mounted back to back at a short distance from each other.
- the two main polarization components of fed dipoles which are the two cross polarizations orthogonally 5 and 6 and are in phase with each other elements of the same dipole.
- + and - the polarities of the dipole elements for their radiation on radiofrequency waves according to a broad diagram band from the electrical energy provided by two non-external sources represented.
- the orientation in FIG. 1 of the radiating cells 1 on the reflector 2 is advantageously chosen so that the crossed polarizations 5 and 6 are not not horizontal or vertical, in order to optimize the characteristics of transmission of dipoles.
- These crossed polarizations are preferentially at + and - 45 ° with respect to the longitudinal axis of the reflector, corresponding to the vertical.
- the conductive elements dipoles are advantageously constituted by plates suitably cut and folded in Vé.
- Each of these conductive elements presents the same, as well as referenced in Figure 3 for the element 12A, a central branch 13 folded longitudinally and two lateral end arms 14 and 15, projecting on one terminal parts called before this branch. At least one tooth 16 is provided on the other end of the branch for mounting the element conductor on the reflector.
- the central branch presents in this realization two longitudinal folds thus dividing it into a plane axial portion 13A, constituting an axial flat, and two fins such as 13B folded on the same side along the flat. Alternatively, it may have only one axial line folding.
- This leg is centered on the end of the branch and is folded to extend facing and the along the central branch, while being outside the V which defines this element 12A or 11A.
- This tab is received inside the V which defines the other element 12B of the dipole 12 or 11B of the dipole 11, where it extends along and opposite the central branch of this other element as visible in Figure 2 or 5.
- This tab is an integral part of this conductive element or alternatively is attached and welded at the front end of its central branch.
- the two conductive elements 12A and 11A differ from each other only by their indentation before 13C or 13'C from where the leg 17 or 17 '. These two notches although little depths have different depths from each other. They thus allow at the legs 17 and 17 'to cross in the front part of the radiating cell, as shown in Figure 2, but without contact with each other.
- the length of the central branch and the two arms of the different conductive elements is equal to a quarter of the wavelength of energy radiated by each dipole.
- the different parts of the conductive elements each of the dipoles constitute a balancing assembly for their power supply from two outside sources represented, to which are coupled the dipoles as described below. _
- the mounting teeth 16 provided on the conductive elements are received in the reflector 2 and welded thereto, each by a weld point such 18 in Figures 5 and 6.
- the end of the tab 17 or 17 ', provided on one only the two conductive elements of each dipole, is received through the reflector but remains isolated from it and is connected by a weld spot 19 to a supply circuit 20 of the dipoles.
- This supply circuit 20 is advantageously made at the rear of the reflector 2, as shown in Figures 5 and 6. Alternatively it can be realized to the front of the reflector, but is then associated with additional elements of decoupling between its different parts connected to cell dipoles radiating.
- It is constituted symmetrically with respect to the longitudinal axis of the reflector 2, being at a small defined distance from the reflector. It includes two supply lines 21 and 22, each coupled to one of the two sources not illustrated. These two lines are parallel to the alignment of radiating cells and located on either side of the direction of this alignment. Each of them has two T-shaped bifurcations that are provided, in this example at both ends of this line. So by referring to same time in Figure 1 or 2, we understand that the two lateral branches 23 and 24 of one of the two bifurcations and similar ones of the other bifucartion on line 21 are each connected to the conductive element 11A dipoles 11 of the four cells 1.
- the two branches of the bifurcations on the line 22 are connected to the conductive elements 12A of the dipoles 12 of the cells 1.
- the other conductive elements 11B and 12B of dipoles 11 and 12 are electrically connected to the reflector 2, grounded to both external sources of energy.
- a connection extension 25 is provided on the middle part of each of the supply lines such as 21. This extension is used for direct connection of one of the external sources in the middle of this line 21. Alternatively it is used for the connection, via a coaxial cable section, from the power line to a coaxial connector mounted at one end reflector and connected to one of the sources. Energy from sources The outer surfaces are thus distributed in a suitable manner on the different dipoles 11 and 12, the amplitude and phase weightings being obtained by variations in the power system parameters, ie the distance of the lines 21 and 22 and their bifurcations with respect to the reflector 2 and the length and width of these lines and bifurcations.
- These lines are flat electrical conductors of the same nature as that of the reflector and the conductive elements of the dipoles 11 and 12, in particularly aluminum or aluminum alloy. They are maintained in at the required distance from the reflector by insulating spacers, no shown, which are provided between them and the reflector.
- FIG. 6 shows the soldering points 18 of the ends of the central branches of the various conductive elements of the dipoles and points 19 more legs on two of the four conductive elements of each radiating cell.
- FIG. 2 shows the holes 29 for passage of the legs such as 17 and 17 'through the reflector, without contact between these tabs and the reflector.
- unrepresented insulating shims can be advantageously provided between each of the legs, such as 17 and 17 ', and the central branch of the conductive element that receives the leg.
- one or more insulating shims not shown are advantageously provided between the integral tab of the conductive element 11A and that integral with the conductive element 12A, which intersect one below on the other but without electrical contact between them at the front of each cell 1 ( Figure 2).
- the portions of these legs that intersect at the front of the cell are oriented according to the crossed polarizations 5 and 6.
- the first two conductive elements respectively two dipoles of the same radiating cell are designated 32A and 31A.
- Their only differences with respect to the conductive elements 12A and 11A of Figures 3 and 4 are specified below.
- the front end of the central branch 33 or 33 ' is not indented.
- an axial slot 38 or 38 ' is provided in this central branch, and extends from an intermediate portion of its front end to its rear end, across the width of the initial flat between the two fins 33B or 33'B.
- each of the conductive elements is constituted by the axial cutting portion of the slot, without its detachment of the part before 33 or 33 'only remaining from the initial flat, and by folding twice this axial portion of cutting. This leg thus extends outside the Vee and next to the conductive element of which it is integral.
- FIG. 9 shows the second conductive element 32B associated with the conductive element 32A of FIG. 7 to then constitute one of the dipoles noted 32 and illustrated in Figure 10. It follows that this second element 32B is similar to the conductive element 32A, except that it is without the tab 37 of this one. In particular, its central branch comprises a slot 38B extending over almost its entire length, to receive the tab 37 without contact between this leg and the conductive element 32B.
- a single light may be provided in a portion intermediate of the front part of the flat part of the central branch, for inserting through this light the tab 37 of the element 32A of FIG. 7 inside the Vee of the conductive element 32B thus modified. This paw 37 then remains without contact with this conductive element that receives it.
- the mode of feeding of the two elements of each dipoles 11 and 12, as the dipole resulting from the variant suggested with reference to FIG. 9, is of the "microstrip" type, with a layer air dielectric thickness defined between the conductive parts which have the + and - polarities and are vis-à-vis.
- the advantage of the embodiment variant described with reference to FIGS. 10 is that the radiating cells thus obtained are lighter and less costly, since the leg of one of the two conductive elements of each dipole is essentially derived from cutting of its central branch and that the other element is itself split.
