Description
Technical field
The utility model relates to a kind of antenna, in particular to a kind of ellipsometry oscillator WIFI antenna.
Background technique
The common symmetric oscillator that existing antenna uses is substantially to work under narrow bandwidth environment, is not able to satisfy full range work
The needs of work, the volume that will lead to equipment if wanting to realize working in whole frequency range increase, and either process and using all very inconvenient.
Summary of the invention
In view of the deficienciess of the prior art, the purpose of the utility model is to provide a kind of ellipsometry oscillator WIFI days
Line.
The technical scheme adopted by the utility model is a kind of ellipsometry oscillator WIFI antenna, including for receiving and dispatching electricity
The radiator and feeding portion of magnetostatic wave signal, are characterized in that, further include dielectric-slab；The radiator is mainly by two ellipses
Symmetrical dipole is constituted, and ellipsometry oscillator is located on dielectric-slab, forms integrated formed structure with dielectric-slab；The feeding portion is
Coaxial line, the core wire and surrounding layer of coaxial line are connected with the two poles of the earth of ellipsometry oscillator respectively.
Preferably, there are gaps for two interpolars of ellipsometry oscillator.
Preferably, feeding point is located at the gap between the two poles of the earth of ellipsometry oscillator.
Preferably, the ellipsometry oscillator'sLong axis is two times of short axle.
The beneficial effects of the utility model are: the ellipsometry oscillator WIFI antenna, by dielectric-slab, symmetrical dipole and coaxial
Line connects and composes, have the advantages that it is small in size, light-weight, the gain of the antenna and standing wave variation it is flat, omnidirectional's excellent performance is convenient for
Maintenance maintenance even can equip cooperating with existing communication, adaptable.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Needed in attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is only the utility model
Some embodiments for those of ordinary skill in the art without creative efforts, can also be according to these
Attached drawing obtains other attached drawings.
Fig. 1 is the structural schematic diagram of ellipsometry oscillator WIFI antenna in the utility model embodiment；
Fig. 2 is that return loss emulates schematic diagram in the utility model embodiment；
Number explanation is as follows in figure: 1 dielectric-slab, 2 ellipsometry oscillators, 3 feeding points, 4 coaxial lines.
Specific embodiment
Keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing 1 and specific
Embodiment is described in further detail the utility model.
The ellipsometry oscillator WIFI antenna that the present embodiment uses, including dielectric-slab；Two are used for transceiving electromagnetic wave signal
Ellipsometry oscillator 2, ellipsometry oscillator 2 is located on dielectric-slab 1, integrated formed structure is formed with dielectric-slab 1, using ellipse
Symmetrical dipole, so that the bandwidth of operation of antenna is multiplied, no longer with the narrow bandwidth environmental work of common symmetric oscillator；Further include
Coaxial line 4, the core wire and surrounding layer of coaxial line 4 are connected with the two poles of the earth of ellipsometry oscillator 2 respectively；Feed in the present embodiment
For point 3 at the gap between 2 the two poles of the earth of ellipsometry oscillator, this structure is able to maintain the stabilization of phase, forms wide bandwidth work
Make.
The long axis of ellipsometry oscillator 2 in the present embodiment is 22.4 mm, and short axle is 11.2 mm.Ellipsometry oscillator 2
The two poles of the earth spacing be 1 mm.The ellipsometry oscillator 2 of the structure facilitates processing, is conducive to the connection of other working devices and antenna,
Suitable in WIFI band operation.
316 line of model of the coaxial line 4 used in the present embodiment.The model FR4 of dielectric-slab in the present embodiment
1.6.The copper plate thickness of ellipsometry oscillator 2 is 0.036MM in the present embodiment.
Simulation calculation is carried out using antenna of the CST microwave studio (CST microwave studio) to the structure, is obtained
To the return loss of this antenna structure, as shown in Figure 2.From simulation result as can be seen that the ellipsometry oscillator of this structure
The return loss of antenna is all in -10dB hereinafter, meet real using needs.Compared with existing antenna, very with standing wave bandwidth
It is more, the advantages of other band operations can be taken into account.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
Or replacement, it should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with the power
Subject to the protection scope that benefit requires.
