In the transmission component of described phase shifting equipment, its drive link 92 can further be provided with flexibly with slave unit 91.Present embodiment is placed in this fact of metallic reflection plate 10 back sides at phase shifter, naturally drive link 92 is placed the back side of metallic reflection plate 10, described slave unit 91 then passes metallic reflection plate 10 and is meshed in the mode that is threaded with the link 22 of the adjusting parts 2 that are positioned at metallic reflection plate 10 fronts.As a kind of substitute mode that is equal to, be arranged at the front of metallic reflection plate 10 as phase shifter, the drive link 92 of described transmission component and slave unit 91 also can relative set in the front of metallic reflection plate 10, and, when the drive link 92 of transmission component places metallic reflection plate 10 fronts, also can omit described slave unit 91, as long as be provided with on this drive link 92 and can regulating the tooth bar (for example radially the screw rod that is cut of two sides) of the threaded engagement on the link 22 of parts 2 or screw or other similar functions parts and this drive link 92 by circumferentially and radially spacing with this.
Further, described adjusting parts 2 also can be replaced by other way of realization, below enumerate two kinds of alternatives: one, can directly adopt the mode of lengthwise shape parts to realize, and allow it to carry out the linear telescopic activity at its longitudinally (being equivalent to the axial of above-mentioned manoeuvre portion 21), and its other end and described transmission component (its slave unit 91 or drive link 92) are achieved a fixed connection, or be connected directly to the movable part 93 of phase shifter, thus, should regulate parts 2 by push-and-pull, can make the drive link 92 of transmission component realize the purpose of straight line back and forth movement equally with indirect realization phase shift, the movable part 93 that perhaps directly makes adjusting parts 2 act on phase shifter carries out the straight line back and forth movement, thereby realizes the purpose of phase shift.They are two years old, can use the gear pair that forms by a plurality of gear configurations to be used for carry-over moment as transmission component, with one of them gear as driving gear, and be provided for handling the adjusting parts 2 of this driving gear, export terminal moment loading in described drive link 92 that is connected with the movable part 93 of phase shifter or the movable part 93 that directly acts on phase shifter with another gear, the feasible move operation that can be caused described movable part 93 by the application of force on driving gear is in like manner realized the function that is synchronized with the movement between phase shifter movable part 93 and the adjusting parts 2.The fit system that has herein fully disclosed between implementation, adjusting parts 2 and the phase shifting equipment of regulating parts 2 all has multiple.
Can further know by inference thus, the mode that realizes described phase shifting equipment also has multiple, not only comprises the above-mentioned local caused replacement scheme of replacing, and comprises that also some have the implementation of bigger variation.Further see also the CN1167545 patent announcement, in the antenna control system that this bulletin provides, disclosed the phase shifting equipment that is different from above-mentioned implementation, the different structure that it adapts to the phase shifter of self has proposed a kind of phase shifting equipment with through-drive.No matter how the concrete structure of phase shifting equipment is realized flexibly, must not break away from and offer the adjusting parts 2 that the user carries out the application of force and match, also must not break away from the torque transmitting that to regulate parts 2 and give the transmission component of the movable part 93 of phase shifter, in view of this, those skilled in the art should know, can utilize its knowledge of grasping to design multiple phase shifting equipment and be used to realize the present invention, therefore, specific implementation about phase shifting equipment is grasped by those skilled in the art, the present invention needn't be exhaustive, and those skilled in the art according to above-mentioned announcement of the present invention change flexibly the phase shifting equipment of different above listed two kinds of technical schemes of coming out, also should be regarded as not exceeding spirit of the present invention.
No matter which kind of flexible way described phase shifting equipment takes realize, usually those skilled in the art all can realize range control, for example, in the scheme that present embodiment Fig. 1 is disclosed, the thread pitch of the link 22 of described adjusting parts 2 in fact just defines the motion range of slave unit 91, thereby also defines the motion range of drive link 92.Further control as need, can also realize range control by the length that the perforate 18 of passing for described slave unit 91 on the metallic reflection plate 10 is set, realize with known alternate manner that perhaps for example the present invention is follow-up will disclose a kind of mode that realizes range control with the moment converting unit.As seen, about straight-line range control, also be that those skilled in the art can realize without creative work according to enlightenment of the present invention.
On the basis of realizing described phase shifting equipment, please continue to consult Fig. 1.As previously mentioned, this antenna 1 is owing to two polarization of existence, thus two signal feed-in ports 41,42 of existence, therefore need be for antenna is provided with decoupling cell 3 so that reduce by two electromagnetic field couples between the feed-in port 41,42, to improve its isolation.Among the present invention, consider signal feed-in port 41, the optimization of 42 isolation need be set up related with the wave beam reclining angle of antenna 1, so that no matter how the angle at the reclining angle of antenna 1 wave beam changes, the feed-in port 41 of this antenna 1, it is optimum that isolation between 42 all keeps, therefore, before the incidence relation of realizing antenna 1 wave beam and antenna 1 isolation, can pre-determine the corresponding relation at the reclining angle of the range ability in decoupling cell 3 residing orientation on antenna 1 and this orientation and antenna 1 wave beam by those skilled in the art.Generally speaking, therefore the best orientation of a corresponding decoupling cell 3 in set wave beam reclining angle, has just been set up this related one to one between the orientation of wave beam reclining angle and decoupling cell 3.Antenna 1 wave beam reclining angle and decoupling cell 3 occupy this corresponding relation between the orientation, realize by mechanical structure.
Please in conjunction with Fig. 1 and Fig. 2, in the first embodiment of the present invention, described antenna 1 further comprises torque transmitting mechanism, this torque transmitting mechanism comprises a driven connector 31 and a drive link 32, this drive link 32 is supported on metallic reflection plate 10 upper surfaces by two Couplings 39 and realizes the slidably setting of drive link 32, also promptly this drive link 32 is circumferentially upwards limited with the footpath at it, make that drive link 32 can be along the longitudinally of metallic reflection plate 10, the longitudinally that also is drive link 32 self is carried out the straight line back and forth movement, one end of drive link 32 is fixedlyed connected with this driven connector 31, driven connector 31 also is threaded with the link 22 of described adjusting parts 2, the manoeuvre portion 21 of regulating parts 2 is driven when rotating by external force, driving described link 22 rotates synchronously, this link 22 rotates to realize the phase shift except that the slave unit 91 that drives described phase shifting equipment, also driving described driven connector 31 is synchronized with the movement to drive described drive link 32, and decoupling cell 3 just directly is fixed on the described drive link 32, thus, in the torque transmitting mechanism, have two torque transmitting links, at first be to accept to regulate the moment that parts 2 are provided by driven connector 31, pass to drive link 32 then, pass torque to described decoupling cell 3 by described drive link 32 again, described decoupling cell 3 is moved.As previously mentioned, because the thread pitch on the link 22 of adjusting parts 2 has substantially played the effect of the motion range of control slave unit 91, in like manner also substantially played the effect of the motion range of controlling driven connector 31, therefore, in the present embodiment, also be equivalent to the effect of the motion range that plays control decoupling cell 3, the range ability of described decoupling cell 3 is determined, and this range ability is to be realized with 31 common cooperations of driven connector in the torque transmitting mechanism by the link of regulating in the parts 2 22, in fact constitute a motion range and determine mechanism, certainly, this range ability also is that those skilled in the art are predetermined.
Those skilled in the art according to the present invention about the announcement of torque transmitting mechanism, also should know: aforementioned implementation about phase shifting equipment, the forms that comprise the form that realizes with drive link 92 and realize with gear pair etc. are applicable to described torque transmitting mechanism too fully.Annexation between drive link 92 that adopts in the phase shifting equipment and the described adjusting parts 2 also must be equally applicable between the drive link 32 and described adjusting parts 2 in the described torque transmitting mechanism.Drive link 92 and its manipulating objects are that the annexation of the movable part 93 of phase shifter (for example adopts and adopts the drive link 32 of screw rod as torque transmitting mechanism as previously mentioned in the phase shifting equipment, be each decoupling cell 3 adaptive one removable unit (not shown), removable unit is threaded with drive link 32 carries out transmission), the decoupling cell 3(in the drive link 32 that also must be substituted into torque transmitting mechanism and its manipulating objects such as the present embodiment or as the moment converting unit in the subsequent embodiment) annexation in.As seen, those skilled in the art can be flexibly with between the total of phase shifting equipment among the present invention and drive link 92 wherein and the adjusting parts 2, connected mode between the manipulating objects of drive link 92 and its transmission of torque end, be equal to and be substituted in the torque transmitting of the present invention mechanism, phase shifting equipment refers to that specifically its transmission component is consistent with the realization principle of torque transmitting mechanism, therefore, replace as a kind of typical technology, in the not shown a kind of execution mode of the present invention, directly the drive link 92 of phase shifting equipment and the drive link 32 of torque transmitting mechanism are united two into one, certainly, in this case, require the movable part 93 of phase shifter and decoupling cell 3 all to be installed on antenna 1 together simultaneously upward conveniently to adopt same drive link to control phase shift and high-isolation maintenance simultaneously.In view of the replaceability of several specific implementations, phase shifting equipment and the torque transmitting mechanism of phase shifting equipment discloses in the above in detail, so disclose the multiple detail of torque transmitting mechanism for this reason no longer in detail.
This structure of Fig. 1 and Fig. 2, make the motion of described decoupling cell 3 set up related with the motion of described adjusting parts 2, because the phase shift campaign of phase shifting equipment has also been set up related with the motion of described adjusting parts 2, so, the motion of decoupling cell 3 is also inevitable sets up related with the phase shift campaign of described phase shifting equipment, no matter directly still indirectly these several incidence relations, all can realize being synchronized with the movement each other, therefore, it also is synchronous regulating the motion of parts 2 and the movable part 93 of phase shifter and the motion of decoupling cell 3, here alleged " synchronously " should be meant that there is the cause and effect inheritance in the motion of regulating between parts 2 and the decoupling cell 3.Regulate parts 2 in case moved in a circle by the application of force, its moment must pass to the movable part 93 and the described decoupling cell 3 of phase shifter by phase shifting equipment and torque transmitting mechanism respectively, the variation at the wave beam reclining angle of antenna 1 and the variation in decoupling cell 3 orientation will take place synchronously, and the concrete orientation of corresponding decoupling cell 3 on metallic reflection plate 10, a wave beam reclining angle of antenna 1, set up related, and corresponding one by one between antenna 1 wave beam reclining angle and decoupling cell 3 orientation.
Real-time change for the ease of the orientation of observing antenna 1 wave beam reclining angle and/or decoupling cell 3, this antenna 1 also is provided with a scale strip 19, these scale strip 19 surfaces are printed with and characterize wave beam reclining angle, and/or, the scale of decoupling cell 3 orientation that occupies or electromagnetic field couples degree or isolation, one end and described slave unit 91(are as shown in Figure 1), one of any fixedlying connected in the drive link 32 of the drive link 92 of described phase shifting equipment, described driven connector 31 and described torque transmitting mechanism, the other end passes cover plate 12 as movable end and is provided with.When adjusting parts 2 are carried out the adjusting of wave beam reclining angle by the application of force, decoupling cell 3 is synchronized with the movement, this scale strip 19 also will be synchronized with the movement, and just can characterize the wave beam reclining angle size of described antenna 1 and/or the orientation of decoupling cell 3 with respect to the length different auxiliary that cover plate 12 stretches out with literal or graphic with it.
As seen, for the dual polarized antenna 1 that first embodiment is disclosed, by will wherein being used to realize the mechanical phase shift structure and the mechanical displacement structurally associated connection that is used to realize the adjusting of decoupling cell 3 orientation of phase shift, drive by same adjusting parts 2, just can realize the adjusted in concert in the wave beam reclining angle and decoupling cell 3 orientation of antenna 1.It is to be noted, the change that variation produced at antenna 1 wave beam reclining angle is followed in the orientation of decoupling cell 3, the electromagnetic field couples between the feed-in port 41,42 of inevitable further reduction antenna 1, isolation between the feed-in port 41,42 of also inevitable further raising antenna 1.Those skilled in the art know, for an antenna 1, according to its specific wave beam reclining angle, can only obtain best or preferable isolation under this angle, therefore, even antenna 1 wave beam reclining angle can be increased or reduce, but changing, the caused isolation of the azimuth shift of decoupling cell 3 may guarantee just that it keeps the not preceding isolation of displacement, might not be to be enhanced or to reduce, accordingly, feed-in port 41, electromagnetic field couples between 42 also might not further be strengthened or be reduced, the target that technology realizes still is to keep the electromagnetic field couples of minimum or lower (in the scope that technical parameter requires to allow), to guarantee high or the most higher isolation, is to keep but not improve or reduce.More very, those skilled in the art should know, when decoupling cell 3 is shifted, even owing to physics control produces natural physical error, cause feed-in port 41, electromagnetic field couples between 42 is reduced by trace or increases, and also should be regarded as the electromagnetic field couples and the high or the most higher isolation that have kept minimum or lower, must be considered as occuping within the spirit scope of the present invention.
As seen, the first embodiment of the present invention, by the control of executing to adjusting parts 2, can realize that phase shift is with when changing antenna lower decline angle, the orientation that the synchronous change decoupling cell is occupied, mainly showing as decoupling cell 3 displacement on its horizontal level for metallic reflection plate 10 at present embodiment regulates, no matter how to change so that finally realize antenna beam reclining angle, but all synchronous change decoupling cell 3 occupy the orientation so that guaranteeing under this wave beam reclining angle that antenna has electromagnetic field couples degree between optimum or more excellent feed-in port to keep high or the most higher isolation.
See also the second embodiment of the present invention that Fig. 3 and Fig. 4 disclose, it has made improvement based on first embodiment to wherein torque transmitting mechanism.Among Fig. 3 and Fig. 4, torque transmitting mechanism has kept drive link 32, and directly the drive link that belong to phase shifting equipment 92 of this drive link 32 with antenna 1 back side is connected by driven connector 31, thus, the drive link 92 of phase shifting equipment slides along its longitudinally after being regulated parts 2 drivings, when the movable part 93 of drive phase shifter moves, the drive link 32 that drives the moment transport sector is synchronously also done the slip of straight line reciprocation type along equidirectional, decoupling cell 3 just in succession with its torque transmitting mechanism on drive link 32, the drive link 92 of phase shifting equipment, regulate parts 2 and set up association, be synchronized with the movement between each related link, thereby can regulate by the manipulation of regulating parts 2 being realized the wave beam reclining angle of adjusted in concert antenna 1 and the orientation of decoupling cell 3.
It is pointed out that the scheme that second embodiment discloses, what addressed during with aforementioned announcement first embodiment is equivalent on movement effects with above-mentioned two kinds of drive links 92 and 32 schemes that unite two into one, and all is same fast movement relations of execution one to.But those skilled in the art should know, the present invention relates to the motion part, all can be according to the needs of decoupling cell 3 displacements and displacement amplitude, by increasing the rate of displacement that gear removes to change the movable part 93 of decoupling cell 3 or phase shifter, in other words, the rotating speed of described adjusting parts 2, rate travel with the movable part 93 of described phase shifting equipment, and the rate travel of described decoupling cell 3, all can be different, look those skilled in the art the demand of antenna 1 design is determined flexibly.Below will describe this principle by other embodiment.
See also the 3rd embodiment that Fig. 5 discloses, with respect to first embodiment, torque transmitting mechanism wherein further sets up a moment converting unit, this moment converting unit comprises first tooth bar 51, driven gear 52, second tooth bar 54 and support guide rod 50, described first tooth bar 51 is fixedly connected on the local location of drive link 32 of described torque transmitting mechanism, described support guide rod 50 be arranged in parallel with the drive link 32 of this torque transmitting mechanism, support guide rod 50 roughly is the U type, its two arm is separately fixed at metallic reflection plate 10, described second tooth bar 54 is set on the middle sliver of this support guide rod 50, so that second tooth bar 54 can slide along this centre sliver, also fixedly install described decoupling cell 3 on second tooth bar 54.Between described first tooth bar 51 and second tooth bar 54, be equipped with the described driven gear 52 that is articulated on the metallic reflection plate 10, this driven gear 52 is meshed with described first tooth bar 51 and second tooth bar 54 respectively.Thus, when the drive link 32 of torque transmitting mechanism is driven, the moment of its parts of self-regulation in the future 2 is through self passing to first tooth bar 51, first tooth bar 51 by with the meshing relation of driven gear 52, driving driven gear 52 rotates, driven gear 52 and then by the meshing relation between itself and second tooth bar 54, give second tooth bar 54 and decoupling cell 3 with torque transmitting again, thereby make decoupling cell 3 under the drive of second tooth bar 54, do direct back and forth movement along the middle sliver of described support guide rod 50.Obviously, though all are straight line back and forth movements, because the acting in opposition of driven gear 52, the direction of motion of decoupling cell 3 is opposite with the direction of motion of described drive link 32, and both forms of motion just present difference.
See also the 4th embodiment that Fig. 6 discloses.Aforementionedly when disclosing second embodiment, address gear application in the present invention in passing, the embodiment that Fig. 6 disclosed has just implemented this application, it is based on structure that Fig. 5 disclosed, by increasing the concrete structure that a littler driving gear 53 of radial dimension changes the moment converting unit, realized the motion of speed change and break-in with respect to the 3rd embodiment, particularly: on the basis of the structure of the moment converting unit that the 3rd embodiment is disclosed, increase the parallel distance between the drive link 32 of described support guide rod 50 and torque transmitting mechanism, make described first tooth bar, 51 engagements, the one described driving gear 53 that is articulated on the metallic reflection plate 10, make this driving gear 53 further be meshed with the described driven gear 52 that is articulated on the metallic reflection plate 10, then keep the meshing relation between described driven gear 52 and described second tooth bar 54, all the other structures all do not change.Thus, in the moment transfer process in the moment converting unit, pass torque to described driving gear 53 from first tooth bar 51, pass to described driven gear 52 again, then just pass to described second tooth bar 54, because of decoupling cell 3 is fixed on second tooth bar 54, so moment has just passed to described decoupling cell 3 from described drive link 92.Conversion through the moment converting unit, as can be seen, described decoupling cell 3 and second tooth bar 54 that is depended on thereof are still carried out the straight line back and forth movement, and the direction of motion of its direction of motion and described drive link 32 is identical, but, because the radial dimension of driving gear 53 is less than the radial dimension of driven gear 52, the number of teeth of driving gear 53 is less than the number of teeth of driven gear 52, the conversion output of moment will produce the effect of slowing down, therefore, although described decoupling cell 3 is all carried out straight line back and forth movement in the same way with drive link 92, movement velocity each other is also inequality, thereby described decoupling cell 3 still is different with the forms of motion of drive link 32.
Further improve this moment converting unit, just can obtain other different implementation, for example, among the 5th embodiment that Fig. 7 disclosed, it only is that with the difference of the 4th embodiment the structure of moment converting unit is different, concrete manifestation driving gear 53 and driven gear 52 coaxial settings therein, driving gear 53 and 52 fixed to one another connections of driven gear, and all be articulated on the metallic reflection plate 10 by coaxial, the driven gear 52 that described radial dimension is bigger is meshed with first tooth bar 51, the less driving gear 53 of described radial dimension is meshed with second tooth bar 54, thus, relative the 4th embodiment, the movement velocity of finally exporting to second tooth bar 54 and the last decoupling cell 3 that is provided with thereof is constant, but direction is opposite with the 4th embodiment.For the drive link 32 of torque transmitting mechanism, decoupling cell 3 among the 5th embodiment is by under the effect of moment converting unit, it is identical with this drive link 32 to carry out direction, but speed is less than the straight line back and forth movement of the movement velocity of this drive link 32, therefore, in the present embodiment, the moment converting unit still makes the forms of motion of decoupling cell 3 be different from the drive link 32 of torque transmitting mechanism.
More than in the antenna 1 that each embodiment disclosed, the change in the orientation of decoupling cell 3 wherein concentrates on the face that is parallel to described metallic reflection plate 10, mainly be to regulate decoupling cell 3 residing lateral attitudes, below announcement is used for comprising and regulating upright position and the reclining angle dual mode of decoupling cell 3 with respect to described metallic reflection plate 10 in the replacement scheme perpendicular to the orientation of the described decoupling cell 3 of face adjusted of described metallic reflection plate 10.
See also the 6th embodiment of the antenna of the present invention 1 that Fig. 8 discloses, this embodiment proposes replacement scheme at the described moment converting unit of aforementioned each embodiment, and all the other structures are not given change.In the present embodiment, described moment converting unit comprises a linkage and a slide mechanism, this linkage comprises that two ends are articulated in the connecting rod 56 between the slide unit 58 of the drive link 32 of described torque transmitting mechanism and described slide mechanism respectively, this slide mechanism comprises erects the limiting component 57 that is fixed on the band sliding tray 570 on the metallic reflection plate 10, be fixed with described decoupling cell 3 on the described slide unit 58, make this decoupling cell 3 occupy metallic reflection plate 10 tops, slide unit 58 is placed in the sliding tray 570 that described limiting component 57 provided, this sliding tray 570 is the lengthwise shape, and its longitudinally is perpendicular to described metallic reflection plate 10, and this slide unit 58 is set to and can does the straight line back and forth movement in the range ability that these sliding tray 570 length are limited.As can be seen, determining of the motion range ability of described decoupling cell 3, not only can realize by the thread pitch of regulating parts 2 as previously mentioned, also can realize by the slide mechanism here, thus enlightenment more can select other flexibly for use by those skilled in the art amount of exercise degree position form so that each embodiment of the present invention is made conspicuous modification.Because described connecting rod 56 1 ends articulate described drive link 32, the other end articulates described slide unit 58, therefore, when described drive link 32 is done straight line back and forth movement on the horizontal direction based on metallic reflection plate 10, just spur described slide unit 58 and do straight line back and forth movement on the vertical direction along described sliding tray 570 based on described metallic reflection plate 10, although both all carry out the straight line back and forth movement drive link 32 and decoupling cell 3, but because of direction difference each other, so both forms of motion must be considered as difference.With the moment converting unit that present embodiment is realized, make the change in location of described decoupling cell 3 no longer be confined to horizontal direction, and solved the problem of regulating the vertical height of this decoupling cell 3 in vertical direction.
Fig. 9 has disclosed the scheme that realizes the rotary adjusting of decoupling cell 3 by another kind of moment converting unit, constitutes the seventh embodiment of the present invention.The 7th embodiment is the differentiation on the basis of the 6th embodiment, among this embodiment, described moment converting unit, it prolongs with the 6th embodiment described connecting rod 56 mechanisms and slide mechanism, but in the sliding tray 570 that this limiting component 57 is provided, its vertical plane realizing the slide unit 58 of slip is designed to tooth bar 580, accordingly, the moment converting unit provides a U-shaped support guide rod 50, two arms of support guide rod 50 are fixed on the metallic reflection plate 10, thereby provide a drive-connecting shaft, in addition, the moment converting unit also provides a gear 55, preferred sector gear, decoupling cell 3 is fixed on this gear 55, and this gear 55 is pivoted mutually with the drive-connecting shaft that described support guide rod 50 is provided, make this gear 55 be able to do circumferential back and forth movement around this drive-connecting shaft, this gear 55 is meshed with the tooth bar 580 that described slide unit 58 is provided, just can realizes the installation of whole moment converting unit.In like manner, after the drive link 32 of torque transmitting mechanism offers described connecting rod 56 mechanisms with moment, slide unit 58 by the described band tooth bar of connecting rod 56 mechanism urges carries out linear slide along the sliding tray 570 that described limiting component 57 is provided, by the meshing relation of tooth bar 580 with gear 55, the rectilinear motion moment of slide unit 58 must pass to the described gear 55 that decoupling cell 3 is installed, thereby make gear 55 drive the circumferential movement that described decoupling cell 3 is provided by the drive-connecting shaft rotation that is provided around described support guide rod 50, as seen, the moment converting unit changes over the straight line back and forth movement of described drive link 32 circumferential movement of decoupling cell 3, forms of motion changes fully, has solved decoupling cell 3 and has carried out the problem that the reclining angle is regulated with respect to metallic reflection plate 10.
This shows, Fig. 8 and Fig. 9 have further disclosed the problem of the orientation adjusting of decoupling cell 3, particularly, Fig. 8 solves the regulation scheme of vertical direction, and Fig. 9 solves the regulation scheme of reclining angle or title circumferencial direction, in conjunction with before the scheme of regulating decoupling cell 3 in the horizontal direction that discloses of each embodiment, as seen, the present invention has provided decoupling cell 3 has been carried out the technical scheme that multiple orientation is regulated, those skilled in the art are on this basis, be enough to realize more complicated adjusting scheme by known mechanical structure, for example, can with oblique slide rail be inserted in oblique slide rail in the decoupling cell 3 that slides combine and provide a brand new to make described decoupling cell 3 along with described drive link 92, carry out the tilting displacement of the motion that combines level and vertical direction simultaneously.Suchlike implementation can be realized under enlightenment of the present invention flexibly by those skilled in the art, and is too numerous to enumerate, do not give unnecessary details for this reason.
More than among each embodiment of Jie Shiing, realize the moment transport sector except that adopting gear pair, described torque transmitting mechanism includes a drive link 32 that is used to carry out the straight line back and forth movement, generally be to be applicable in the antenna 1 with 7 groups of battle arrays of two or more radiating elements, the antenna 1 of this structure often need be at a plurality of described decoupling cells 3 of a plurality of positions relative set, for the ease of integrated control, adopting 32 pairs of a plurality of decoupling cells 3 of drive link to carry out centralized control is not only economy but also mode efficiently.Yet, in the embodiment that the present invention does not disclose, more be applicable to the situation of the less decoupling cell 3 of controlling the size separately, described torque transmitting mechanism can be made of a series of gear drive, for example drive a gear by the link 22 of regulating parts 2, again by remaining gear of this gear driven, finally the moment output shaft drive decoupling cell 3 by terminal gear moves, so just, needn't adopt described drive link 32, therefore, though the torque transmitting mechanism of aforementioned each embodiment has adopted drive link 32, should not be construed as limitation of the invention.
The way of realization of described decoupling cell 3 is also known by those skilled in the art, the shape of decoupling cell 3 is various, can be arbitrary forms such as sheet, column, spherical, folding shape, also can be more complicated structures such as " # " font, hollow out shape, usually adopt according to qualifications by those skilled in the art, do not give unnecessary details for this reason.Decoupling cell 3 is for the orientation of metallic reflection plate 10, both can occupy the superjacent air space of radiating element 7, for example shown in Figure 10, also can occupy the space, one or both sides, below of radiating element 7, for example shown in Figure 11, can also occupy the following side space between adjacent two radiating elements 7, for example shown in Figure 12, or the like.According to the decoupling cell 3 that Figure 11 and Figure 12 disclosed, can make an one part or all come close to or in contact with described metallic reflection plate 10, thus, decoupling cell 3 is with 10 close contacts of metallic reflection plate or directly contact, be in the radiation field, both form in fact and conduct, coupling unit is grounded or equivalent ground connection, coupling effect strengthens greatly like this, but not isolated parasitic couplings, enough big enough near when both coupling surfaces, just be equivalent to an electric capacity, directly conducting under the effect of high frequency alternating electromagnetic field.In addition, also can be different in the same antenna 1 inner different decoupling cell 3 orientation that occupies of installing and sensing, for example Figure 13 disclosed is positioned at two decoupling cells 3 on the same drive link 32, one of them sensing also places between adjacent two radiating elements 7, and another then places the place, side space of two radiating elements 7.Obviously, all be well known to those skilled in the art, and focusing on of realizing of the present invention limit a range ability for the orientation of decoupling cell 3 changes, therefore, do not make qualification for this reason at the concrete riding position of decoupling cell 3.
