The control module is such as, but not limited to embedded scm.
The BBS(Bulletin Board System) of the present invention obtains notice information by wireless communication module from Cloud Server, has bulletin
In time, the high feature of information quality.
Fig. 2 is the batch micro operations diagram of inventive antenna structure.
Fig. 3 is the concrete structure plan view of inventive antenna device.
A kind of optional embodiment as antenna assembly.
As shown in Figures 2 and 3, the antenna assembly includes：Substrate layer（It is not shown in figure）, metal layer（111,112,
114,115）And parasitic element 113；Substrate layer can be the PCB layer of routine, or the common substrate material in this field,
Metal layer is set on substrate layer, and parasitic element 113 is arranged in the metal layer, and metal layer is located at antenna substrate layer and posts
Between raw unit；At least four opening void region of setting on metal layer, the parasitic element is ranked adjacent on the metal layer
Between opening, the quantity of parasitic element is three, and the distance between parasitic element is equal, and the dimensions length of parasitic element is identical,
The opening void region area in region is identical between parasitic element, and the opening void region area of the exterior domain of parasitic element can be with
Differ；The feed element F of the antenna assembly is arranged in the centre position of parasitic element length direction.
Referring to Fig. 2, antenna manufacture craft of the invention is special, and the mode of batch production so that the cost of antenna is controlled
System, the substrate of batch production can be the pcb board of routine, simply and reduce cost.
Referring to Fig. 3, the length of parasitic element 113 is equal to opening（The length of the opening of the first from left side two or right side are single
The length of opening）The length of void region, the width of parasitic element 113 is no more than the centre for measuring both sides adjacent apertures void region
Distance.The introducing of parasitic element can effectively control antenna element size, and the longitudinal gain for controlling radiating element is special
Property, the suitable parasitic element size signal longitudinal to radiation has carried out effective guiding and focusing, ensure that antenna size subtracts
Hour can targetedly promote the radiation gain of antenna again, however can be caused if the specific size design of parasitic element is improper
Larger radiation offset preferably selects reasonable size here, and the size of antenna parasitic element is appropriate ranging from this case
Long 1.5-2.5CM, wide 2-4mm；Preferably, the dielectric constant values ranging from 10-20 of parasitic element is selected.
Fig. 4 is other structure forms of inventive antenna structure.
In addition to this, the aperture position of void region also will produce relatively straightforward shadow to the radiation effect of antenna assembly
It rings, as it can be seen that the Edge Distance when 111 upper end of open area Edge Distance metal layer is less than apart from 112 lower end of metal layer in attached drawing 4
Edge Distance when, the high frequency performance of antenna can significantly get a promotion, the distance areas at the Edge Distance both ends of open area
When identical, the low frequency performance of antenna can significantly enhance.It can be adjusted by adjusting the aperture position between different parasitic elements
The different frequency range performance of antenna, such as dual frequency operation or multi-band operation.
The opening of metal layer can be one, can also be two or more, and when open amount is more, the multifrequency of antenna is special
Property can be more apparent, however its radiation gain can be lost, can be by making at least two open areas as making up
Opening size is identical, and can the radiating bands of needs be carried out with gain superposition coupling by identical size makes up, this superposition
Coupling couples realization by common electromagnetic between metal layer open area and parasitic element.The parasitic element divides metal layer
At several slip gauges shape then, such as rectangle, square etc..
Referring to Fig. 3, the centre position of one of parasitic element is provided with feed element F, and the concrete mode of the feeder equipment can
Think the patch mode on surface, can also be realized by passing through the coaxial feed mode of substrate layer, only it is occupied
Space can be larger compared to patch, but the antenna transmission characteristic and effect of its acquisition have all benifits.
This antenna assembly is collectively formed by substrate layer, metal layer and parasitic element, several by being arranged on the metal layer
The opening void region of size and the outer fix setting parasitic element for being incorporated in void region, are engraved by parasitic element and opening
The superposition coupling effect of empty region realizes the micromation of antenna assembly and the advantageous effect of high-gain.This BBS(Bulletin Board System)
Method for manufacturing antenna is simple for process, manufacturing cost is low, and manufactured antenna impedance is low, high gain, can effectively meet wireless biography
Defeated different performance requirement.
It is enlightenment with above-mentioned desirable embodiment according to the present invention, through the above description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property range is not limited to the contents of the specification, it is necessary to determine its technical scope according to right.
