Embodiment
For better understanding technology contents of the present invention, the preferred specific embodiment explanation of special act as follows.
Below please in the lump referring to figs. 1 to the embodiment of Fig. 3 about flat plate antenna structure of the present invention.Fig. 1 is the decomposition diagram of flat plate antenna structure of the present invention; Fig. 2 is the schematic perspective view of flat plate antenna structure of the present invention; And Fig. 3 is the combination sketch map of flat plate antenna structure of the present invention.
To shown in Figure 3, flat plate antenna structure 1 comprises first sheet metal 20, intermediate layer 30, becket 40 and second sheet metal 50 like Fig. 1.Wherein intermediate layer 30 comprises first hole 31, and intermediate layer 30 is arranged on first sheet metal 20 and with first sheet metal 20 and links; Becket 40 passes first hole 31 and first sheet metal 20 links.Second sheet metal 50 comprises that second hole, 51, the second sheet metals 50 link with becket 40, and second sheet metal 50 and the binding of first sheet metal, 20 rivetings, so that intermediate layer 30 is coated by first sheet metal 20 and second sheet metal 50 with becket 40.Whereby, second sheet metal 50 can electrically conduct with first sheet metal 20 by riveting, and can electrically conduct by the becket 40 and first sheet metal 20.
As shown in Figure 3, intermediate layer that first sheet metal 20 and second sheet metal 50 are coated 30 forms resonant cavitys 11, and by the characteristic of the diameter adjustable antenna that changes first hole 31 and becket 40.Because the change of becket 40 diameters, changed the scope of resonant cavity 11, so antenna characteristics changes thereupon also.
In one embodiment of this invention, intermediate layer 30 is a plastic sheet, and plastic sheet has the characteristic of low-k, so the instead Teflon is as a base material of flat plate antenna structure 1.As shown in Figure 3, for strengthening combining closely of flat plate antenna structure 1, first sheet metal 20 and second sheet metal 50 link with the mode that riveting links, but the present invention is not as limit.In one embodiment of this invention, intermediate layer 30 is that (high density polyethylene, HDPE), but the present invention is not as limit for high density polyethylene (HDPE).
As stated, becket 40 effect in the present invention by the diameter of adjustment becket 40, can be adjusted the antenna characteristics of flat plate antenna structure 1 except electrically conduct first sheet metal 20 and second sheet metal 50.Becket 40 is because of having intensity in addition, and therefore when first sheet metal 20 engaged with second sheet metal, 50 rivetings, the weight in the time of can avoiding first sheet metal 20 and second sheet metal 50 because of riveting was out of shape.For example, as shown in Figure 4, if flat plate antenna structure 1 lacks becket 40, then flat plate antenna structure 1 is when riveting engages, and the weight part when second sheet metal 50 maybe be because of riveting is out of shape.
As shown in Figure 3; In one embodiment of this invention, first sheet metal 20 has protuberance 201, and this protuberance 201 has corresponding helical structure (figure does not show) with becket 40; So that first sheet metal 20 and becket 40 screw engagement, but the present invention is not as limit.The intermediate layer 30 and first sheet metal 20 link with bonding mode, and the intermediate layer 30 and second sheet metal 50 also link with bonding mode.For instance, 20 of 30 and first sheet metals and intermediate layer 30 and second sheet metal 50 add a two-sided adhesive sheet respectively in the intermediate layer, can reach bonding mode and link, but the present invention is not to exceed.
In one embodiment of this invention, first sheet metal 20, second sheet metal 50 and becket 40 are copper or copper alloy, but the present invention is not as limit.For instance, first sheet metal 20, second sheet metal 50 and becket 40 also can be silver or silver alloy; So long as the good metal of conductivity, all can be first sheet metal 20 of the present invention, second sheet metal 50 and becket 40 employed materials.
Below please in the lump with reference to figure 5A and Fig. 5 B sketch map about the embodiment of the electronic installation with flat plate antenna structure of the present invention.
Shown in Fig. 5 A, the present invention provides a kind of electronic installation 7A with flat plate antenna structure, and it comprises electronics 70A and flat plate antenna structure 1.In one embodiment of this invention, electronics 70A is a global positioning system, but the present invention is not as limit.
Shown in Fig. 5 B, the present invention provides a kind of electronic installation 7B with flat plate antenna structure, and it comprises electronics 70B and flat plate antenna structure 1.In one embodiment of this invention, electronics 70B is a satellite radio, but the present invention is not as limit.
To sum up institute is old, and no matter the present invention all shows it totally different in the characteristic of conventional art with regard to purpose, means and effect; But it should be noted; Above-mentioned many embodiment have been merely to be convenient to explanation and give an example, and oneself should be as the criterion scope of the present invention so that claims are said, but not only limits to the foregoing description.
