Summary of the invention
Purpose of the present invention is now, improves such antenna assembly, it perhaps under the situation of other antenna that is applied as other service (for example the mobile radio service of different frequency scope etc.) as basic pattern.
Reach this purpose according to the present invention by the feature that illustrates in the claim 1.Explanation favourable form of implementation of the present invention in all dependent claims.
Beyond thought solution is provided within the scope of the present invention, realize a kind of with press the similar antenna assembly of antenna assembly of Fig. 1.But its relatively by the example compactness of Fig. 1 how constitute.
In scope, advise according to solution of the present invention, in antenna first or the surface mount elements of (passive or parasitic) conduction that is arranged with interval above radiating surface of elementary paster antenna in, additional paster antenna B shown in Fig. 1 is set, this surface mount elements be provided with at least in part around and away from the edge or the wall of the radiating surface orientation of antenna A.
In other words, additional second or the secondary paster antenna that for example are provided with for the GPS service is installed in in box-like or the surface mount elements of box like the parasitism that constitutes, the top of the radiating surface under the previous relatively described antenna A of the latter is arranged on.
Like that this another paster antenna can highly insert this box-like with a part or the box in the surface mount elements.It can with its end face protrude in first antenna box-like or box like surface mount elements around the edge.
But also might with the surface mount elements of the parasitism of first paster antenna to small part around edge termination above the surface of described another paster antenna, therefore additional paster antenna insert fully be provided with around the edge or around the spatial accommodation of surface mount elements of marginal portion in.
Be in particular described another paster antenna that GPS service is provided with to this can by the centre connect insulating barrier be contained in and/or be fixed on first paster antenna parasitism box-like or box like on the surface mount elements.
Also possible, described another paster antenna that is in particular GPS service setting is not provided with the ground plane of oneself, and substrate directly be bearing in first paster antenna parasitism box-like or box like on the surface mount elements, thereby the surface mount elements of the parasitism of first paster antenna also constitutes the ground plane of described another paster antenna simultaneously.
Show within the scope of the invention at last, parasitic at least in part with around the edge or around the surface mount elements that constitutes of wall can be formed on the bottom surface of described another paster antenna and/or around the side, edge on.Therefore surface mount elements like that above-mentioned box-like is not set fully or the box as independent member, that is completely or partially not as independent member setting, and with described box-like or box like the corresponding current-carrying part of surface mount elements completely or partially be formed on the appropriate section of described another paster antenna as metal layer.The surface mount elements of the parasitism of elementary antenna completely or partially can be formed on the bottom surface of described another paster antenna by metal layer in this case and/or around lateral edges on.Can be when making described another paster antenna, realize such step, similar or rather as when making paster antenna itself, promptly on the substrate of such paster antenna to the paster face of sending direction coated with conductive with on the end face and bottom surface of the substrate that on the opposed side ground plane of conduction is coated in paster antenna with the form of metal layer.In this case therefore the surface mount elements another box-like or box-like of the parasitism that above the radiating surface of paster antenna, is provided with in the prior art of cancellation as physics element independently.
Described metal layer on the paster antenna, on its bottom surface and/or one or more around side surface on needn't constitute totally continuous, and along can have many places discontinuities, the discontinuities on each folding corner region for example around direction, can be different high, in addition can with below ground plane or below the surface mount elements electricity of parasitism separate.The metal layer of mentioning is on side surface even can extend to the end face of described another paster antenna always, but should separate with the antenna patch electricity of the power supply of working of described another antenna there.
Particularly the moulding of described another paster antenna that is particularly substrate, down the moulding of ground plane (it also can be simultaneously the surface of surface mount elements of the parasitism of first paster antenna) and the paster face that works that is provided with on transmission/reception side can be foursquare or rectangle.That these surfaces can constitute n limit shape and even have other a moulding that is different from regular polygon.Each sidewall of the substrate of Fu Jia paster antenna and/or each sidewall that is provided with at least in part there and extend away from first paster antenna or each side surface axial direction that also needn't necessarily the be parallel to paster antenna direction of each ground plane and/or paster face (that is perpendicular to) constitutes at last, and can have the edge of rounding, the edge of chamfering etc.With regard to this respect also without limits.
With respect to according to prior art with by the known solution that Fig. 1 describes, can reach within the scope of the invention and be used for obviously reducing according to the space requirement of antenna sets zoarium of the present invention.The overall size that reduces particularly has importance for the top antenna system, and it has strict design, wherein because the design objective of being scheduled to by the auto-maker generally only provides few space requirement for the configuration of the outer cover of antenna.
More beyond thoughtly to this be, according to the corresponding car antenna of known DE 10 2,006 027 694 B3 itself well electrical characteristics not only can continue to keep, and even can also be improved, though and this reduced the structure space that needs.But this is not conspicuous, because embed another antenna in the surface mount elements that is provided with.Therefore this also is more beyond thought, because this antenna system should be applicable to the reception of SDARS service and must very strictly estimate corresponding antenna structure for the reception of this service, because antenna does not have the good receiving feature of corresponding requirement.
Also can influence the characteristic of the gps antenna of top within the scope of the invention sharply.This also is beyond thought.And within the scope of the invention Shang Fang gps antenna also can constitute bigger that is in case of necessity in addition constitute as be in below SDARS paster face big.This is another the basic difference with prior art, because here Shang Fang paster antenna is always less than following and must be like this.Tangible improvement is also guaranteed in the reception of expanding as this service by the GPS paster antenna.Within the scope of the invention in addition a kind of preferred form of implementation be possible, therein, the supporting member of the paster antenna of top or the dielectric of top greater than be in the below the SDARS paster.This is last even cause the improvement of the characteristic of SDARS paster.
And can realize having the main aerial of two patch radiator within the scope of the invention, it is assembled fully and can be used as the unit then in preposition step in mass-produced scope and is installed on antenna underframe or the antenna base.This is with respect to having tangible advantage according to the production process of the traditional antenna assembly of prior art manufacturing when (as describing by Fig. 1).

Embodiment
Below at first relate to embodiment by Fig. 2 to 5, paster antenna shown in it, it has the surface and the layer of the overlapping setting of axis Z vertically.Such surface mount elements is known by DE10 2,006 027 694 B3 on the principle, and its disclosure is all quoted.But there is not additional paster antenna by the known surface mount elements of DE 102,006 027 694 B3.
Can find out that from sectional elevation paster antenna A has the ground plane 3 of conduction on its so-called bottom surface or installed surface 1 by 2 signal.On ground plane 3 or with respect to ground plane, the supporting member 5 of dielectric is set laterally offset is arranged, its in vertical view, have usually profile 5 ', this profile meet the profile 3 of ground plane 3 '.But the supporting member 5 of this dielectric also can be specified to big or reduced size and/or be provided with the profile 3 that is different from ground plane 3 ' profile 5 '.In general the profile 3 of ground plane ' can be n limit shape and/or even be provided with the part of curve or constitute curve, though this is of little use.
The supporting member 5 of dielectric comprises its end face 5a and its bottom surface 5b having enough height or thickness, and it generally is equivalent to many times of thickness of ground plane 3.Be different from the approximate ground plane 3 that only is made of two-dimensional surface, therefore the supporting member 5 of dielectric constitutes the said three-dimensional body with enough height and thickness.
Be different from dielectric 5 and also can establish another kind of dielectric or another kind of dielectric structure, also adopt air or have air layer on another dielectric next door.Then naturally corresponding supporting arrangement must be set when adopting air as dielectric, it for example comprises overhead, bolt, pillar etc., so as supporting and fixedly other of paster antenna be in its top and following element that also will illustrate.
Be opposite to the radiating surface 7 that constitutes conduction on the end face 5a of bottom surface 5b, it can be interpreted as two-dimensional surface equally once more approx.This radiating surface 7 is via supply lines 9 power supply and excite, supply lines preferably along horizontal direction, particularly perpendicular to radiating surface 7 from the below by base (underframe) S, ground plane 3 and the supporting member 5 by dielectric in corresponding hole or extending the passage 5c accordingly.
From usually below tie point 11 on, can connect the coaxial cable that is not shown in further detail thereon, thereby the inner wire of unshowned coaxial cable is electrically connected with radiating surface 7 also with supply lines 9 then.The outer conductor of unshowned coaxial cable is electrically connected with the ground plane 3 that is in the below.The coaxial cable that replacement connects also can adopt and correspondingly be connected microstrip line.
Describe a kind of paster antenna in the embodiment later by Fig. 2, it has dielectric 5 and be foursquare shape in vertical view.But this shape or corresponding profile or outline line 5 ' also can have are different from the foursquare shape and the shape of n limit shape in general.Though be of little use, even the external boundary of curve may be set also.
The radiating surface of installing on the dielectric 57 can have be in it below the identical profile of dielectric 5 or outline line 7 '.In an illustrated embodiment, basic configuration adapts to the outline line 5 of dielectric 5 ' and constitute foursquare equally, " (only being shown in the vertical view by Fig. 3), it we can say that the right-angled triangle by removing isosceles constitutes but to have the portion of scabbling 7 on two opposed turnings.Therefore outline line 7 ' also can constitute the outline line of n limit shape in general, or profile or even be provided with the external boundary 7 of curve '.
Described ground plane 3 and radiating surface 7 are sometimes referred to as " bidimensional " surface, because its thickness is so little, consequently we can say to be referred to as " solid ".The thickness of ground plane 3 and radiating surface 7 is usually less than 1mm, is generally less than 0.5mm, particularly less than 0.25mm, 0.20mm, 0.10mm.
So far Shuo Ming paster antenna can for example comprise commercial paster antenna commonly used, preferably include so-called ceramic paster antenna, and it has the supporting course 5 of the dielectric that is made of ceramic material.Draw according to further description, exceed the paster antenna of explanation so far, further constitute a kind of paster antenna on the meaning of the paster antenna A that piles up, the top of wherein superincumbent radiating surface 7 (being preferably perpendicular to the parallel spaced awayly dislocation of radiating surface 7 ground is provided with) added parasitic surface mount elements 13 is set.Surface mount elements that this is parasitic 13 constitutes makes its described relatively ground plane 3 and radiating surface 7 have three-dimensional structure, and this three-dimensional structure comprises different with it that is compare with ground plane 3 or radiating surface 7 big height or thickness.
The preferred supporting arrangement 19 (the particularly supporting arrangement of dielectric) that adopts with certain thickness or height 17, fix and support parasitic surface mount elements 13 above it, the supporting arrangement 19 of this dielectric preferably includes and adheres to or assembly layer 19 ', its for example can constitute the adhesion of so-called both-sided adhesive and assembly layer 19 '.Can adopt foam band, adhesive pad of the adhesive tape of commercial both-sided adhesive commonly used or both-sided adhesive etc., it has corresponding above-mentioned thickness for this reason.This opens up simple possibility, and is above it that described surface mount elements 13 is fixing and be installed on the end face of commercial paster antenna commonly used, particularly commercial ceramic paster antenna commonly used.
The described paster antenna A that piles up only is positioned in Fig. 2 on the underframe S that represents as straight line, that is is positioned on the base, and it also indicates with mark 20 additionally.This base can for example be configured for the basic underframe 20 of car antenna, can install according to antenna of the present invention on the next door of other antenna that is used for other service in case of necessity thereon.Can for example be used for receiving satellite signal or land signal as antenna especially according to the paster antenna A that piles up of the present invention, for example so-called SDARS service.But also without limits for the application of other service.
As conspicuous by the space diagram of pressing Figure 4 and 5, this surface mount elements 13 have structure rectangle or foursquare comprise corresponding profile 53 ', but be not limited to this moulding.Among Fig. 4 in vertical view with rectangle or square the surface mount elements 13 above illustrating, comprise around edge or wall, to also discussing below it.According to the top view illustration among Fig. 3, parasitic surface mount elements 13 also can have the moulding different with it, for example the shape of n limit shape.Shown in this Fig. 3, surface mount elements 13 for example can be provided with the portion of scabbling 13 on two opposed angle points ", they for example are adjacent to the portion of scabbling 7 of the radiating surface that works 7 of the top of paster antenna A " is provided with.
As finding out by each figure, that install on supporting arrangement 19 or fixing thereon, that constitute by the box pattern that is open upwards, parasitic surface mount elements 13 comprises basal plane or median plane 53 "; its be provided with in an illustrated embodiment around the edge or around lath 53d (in general that is corresponding projection 53d), it is by the basal plane 53 that also is parallel to ground plane " flat transverse, especially vertically rise.Such surface mount elements 13 can for example be made by the sheet metal of conduction by cutting and crimp, wherein each around lath 53d can be for example be electrically connected mutually at each folding corner region by welding (this external core 53 " in also a plurality of spaces can also be set, to discussion in addition below this).
The second paster antenna B is in the top of this secondary surface mount elements 13, as shown in other the figure.It is such that the size of the second paster antenna B is determined about its length and width, promptly its size for example be slightly smaller than at least the surface mount elements 13 of parasitism each around lath 53d between inner freely extending longitudinally size and extending transversely size.This opens up possibility equally, promptly paster antenna B can be inserted among the inner chamber 53a of surface mount elements 13 with different sizes.In other words, be in the water surface of below that is the boundary face 101 of below enter among the inner chamber 53a of parasitic surface mount elements 13, that is the below of boundary face 53c up, each lath, edge or the outer wall 53d of boundary face 53c by parasitic surface mount elements around top edge predetermined.
The second paster antenna B comprises the substrate (dielectric) 105 with end face 105a and bottom surface 105b equally once more, wherein on the end face 105a of transmission/receive direction (that is away from paster antenna A direction), constitute at substrate 105 second or the radiating surface that works 107 of secondary paster antenna B as conductive surface, and the second affiliated ground plane 103 of the second paster antenna B is set towards paster antenna A (that is on the 105b of bottom surface).
Can find out by each accompanying drawing, laterally and especially another passage or another hole 105c are set perpendicular to patch radiator surface the axial Z direction of whole antenna assembly (that is along).This passage is by underframe 20, by first or elementary paster antenna A (that is by its ground plane, dielectric and radiating surface up), by supporting arrangement 19 and the parasitic conversion element 13 that on dielectric, connects, by extend to second radiating surface 107 above being at the supporting course of the second paster antenna B that follows in case of necessity on the surface mount elements and second ground plane 103 by belonging to paster antenna B and the supporting member 105 by dielectric always, that is second radiating surface 107 of the second paster antenna B.
The joint of coaxial cable on the bottom surface of underframe 20, thereby give radiating surface 107 power supplies via the supply lines that in passage, extends 109.The outer conductor of coaxial stube cable is electrically connected on ground plane 3 on joint.Naturally also can replace coaxial stube cable that little band connecting line is set in this embodiment.
In each embodiment described so far, the height 115 of the second paster antenna B (comprising on the bottom surface that is in ground plane 103 in case of necessity supporting and/or fixing and/or adhesive layer 111) adjacent to surface mount elements 13 end faces of parasitism greater than height 117 that is greater than the surface mount elements 13 of parasitism around each edge 53d.But the height of surface mount elements also can homoecious surface mount elements 13 around the just the same height of each edge 53d.
Illustrate by Fig. 6, parasitic surface mount elements 13 around each edge 53d in addition can be higher than the height of the second paster antenna B, thereby the second paster antenna B inserts among the inner chamber 53a of parasitic surface mount elements 13 fully.Fig. 6 is different from Fig. 2 and illustrates in addition, and extending longitudinally size that the relative z axis of another paster antenna B extends and extending transversely size are bigger and can at least almost fill up the inner chamber of parasitic surface mount elements 13 fully.
