Embodiment
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in detail embodiment of the present utility model below in conjunction with accompanying drawing.
Set forth a lot of detail in the following description so that fully understand the utility model.But the utility model can be much different from alternate manner described here to implement, those skilled in the art can when doing similar popularization without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public concrete enforcement.
Referring to Fig. 1, cylinder conformal coated by dielectric antenna comprises at least one antenna body, and antenna body can comprise dielectric layer 1 and radiation patch 2.Cylinder is conducting post, such as, be body.
Wherein, dielectric layer 1 is installed to cylinder D surface, radiation patch 2 is installed on the surface of dielectric layer 1 cylinder D dorsad, namely be followed successively by cylinder D the end of to table, dielectric layer 1, radiation patch 2, and one end of radiation patch 2 and cylinder D short circuit, all the other ends and cylinder D open a way, according to profile and the size of required antenna, cylinder D surface is transformed, can by offering groove or hole, antenna body is installed to cylinder D on the surface with adapting to, cylinder D can be such as guided missile, the concrete structure of radiation patch 2 is not as restriction, it can be the radiant body being used for realizing aerial radiation in prior art.
In FIG, the shape of dielectric layer 1 and radiation patch 2 is rectangle, the width of radiation patch 2 is less than the width of dielectric layer 1, and length can be suitable, one end of radiation patch 2 is directly electrically connected to cylinder D surface, realize short circuit, all the other ends are then within dielectric layer 1 scope, thus all the other ends of radiation patch 2 and cylinder D not conducting, realize open circuit, to realize the impedance matching of antenna body and cylinder D, dielectric layer 1 and elastic patch 2 can also be other shapes, size also can adjust as required, impedance matching can be realized, when radiation patch 2 is two ends, one end and cylinder D short circuit, the other end and cylinder D open a way.
Referring to Fig. 1 and Fig. 2, radiation patch 2 is installed on the surface of dielectric layer 1 by nonmetal screw 3, because nonmetal screw 3 is non-conductive, thus can be connected to cylinder D surface in one embodiment further, certainly, can only radiation patch 2 be fixed on dielectric layer 1.In one end that radiation patch 2 and cylinder D are opened a way, metallic screw 3 ' can be used radiation patch 2 to be directly installed on cylinder D, or can be also non-metallic screw, realize the electric connection of radiation patch 2 and cylinder D.
Referring to Fig. 1, dielectric layer 1 can be arranged on damaged surface by metallic screw 9, and this metallic screw 9 is without radiation patch 2, and thus when arranging the size of dielectric layer 1 and radiation patch 2, dielectric layer 1 can have larger area, to leave the position that can connect.
The installation of radiation patch 2 and dielectric layer 1 preferably makes cylinder D surface smoothing, and the end face of each screw preferably, can be mutually concordant with cylinder D surface.
Continue referring to Fig. 1 and Fig. 2, the feedback point place of radiation patch 2 offers counterbore 4, installs feedback point interface, in other words feeder line and signal amplitude loophole in counterbore 4, adopts counterbore 4 to design, solder joint can be made not protrude from the surface of radiation patch 2, ensure surface smoothness.
In a preferred embodiment, the conformal coated by dielectric antenna of cylinder can comprise two antenna bodies, and two antenna bodies are coupled by power division network.Concrete, referring to Fig. 3, two antenna bodies are oppositely arranged on cylinder D surface, the cylinder D illustrated is cylinder, one antenna body is arranged in a part for cylinder D side surface, another antenna body is arranged on another part of the corresponding last antenna body of cylinder D side surface, two fix up an aerial wire the center of circle Central Symmetry of body about cylinder D cross section, the power division network coupling two antenna bodies comprises long cable 5 and stub cable 6, long cable 5 one end connects an antenna body, the namely feedback point of this antenna body radiation patch 2, stub cable 6 one end connects another antenna body, the namely feedback point of this antenna body radiation patch 2, the other end of long cable 5 is connected by a power splitter 7 with the other end of end cable 6, the signal that two antenna bodies are launched can be exported by total mouth 8 by power splitter 7, or also can pass through total mouth 8 Received signal strength, identical two-way is divided into by signal to be transferred to two antenna bodies.
Better, to be 0.5 λ, λ be the length difference of long cable 5 and stub cable 6 that antenna receives or the wavelength of signal launched, antenna pattern can be made milder, improve the gain of directional diagram interference region.The concrete length of cable can adjust according to actual conditions, certainly, the length difference of long cable 5 and stub cable 6 also can be chosen as other values, the conformal coated by dielectric antenna of cylinder still can work, just may consider that performance is slightly not good enough from directional diagram, but not affect the effect of cylinder conformal coated by dielectric antenna volume miniaturization.
In an optional embodiment, the base material of dielectric layer 1 is polysulfone material, the base material of radiation patch 2 can be red copper material, only to provide optional material at this, not material being limited to this, can also be that other can do the dielectric material of dielectric layer 1 and can do the conductor material of radiation patch 2.
The utility model by coated by dielectric antenna, realizes the antenna of Conformal with cylinder, can reduce the volume of existing pattern-band antenna, achieves the beneficial effects such as miniaturization, integration and cylinder be conformal.
Although the utility model with preferred embodiment openly as above; but it is not for limiting claim; any those skilled in the art are not departing from spirit and scope of the present utility model; can make possible variation and amendment, the scope that therefore protection range of the present utility model should define with the utility model claim is as the criterion.
