Block.
The signal acquisition terminal of the wireless module obtains temperature levels by an A/D module from the end of oppisite phase of voltage comparator
Signal, i.e. temperature data.
Since the environment of each irrigated area is extremely complex, frequency shift (FS) is influenced based on high-order electrostrictive coefficient environment so that wireless
Communication efficiency substantially reduces, especially farm area, is related to large area irrigation, should more consider wireless telecommunications efficiency；Therefore,
Need to obtain preferable wideband and gain characteristic for this antenna assembly, can resist frequency shift (FS) causes radiation efficiency significantly to glide
Phenomenon, ensure the stability of data transfer.
As shown in Figures 3 to 5, based on above-mentioned purpose, antenna assembly provided by the invention, and then the more of wireless telecommunications are met
Kind performance requirement, specifically, including：Substrate layer（Do not shown in figure）, metal layer（111,112,114,115）And parasitic element
113；Substrate layer can be conventional PCB layer, or the common substrate material in this area, sets metal on substrate layer
Layer, the metal layer set parasitic element 113, and metal layer is between antenna substrate layer and parasitic element；On metal layer
At least four opening void regions, between the parasitic element ranks opening adjacent on the metal layer, parasitic element are set
Quantity is three, and the distance between parasitic element is equal, and the dimensions length of parasitic element is identical, and region opens between parasitic element
Mouth void region area is identical, and the opening void region area of the exterior domain of parasitic element can not wait；The feedback of this antenna assembly
Electric unit F is arranged on the centre position of parasitic element length direction.
Referring to Fig. 3, antenna manufacture craft of the invention is special, and the mode of batch production make it that the cost of antenna is controlled
System, the substrate of batch production can be conventional pcb board, simple and reduce cost.
Referring to Fig. 4, 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 control longitudinal gain of radiating element special
Property, suitable parasitic element size has carried out effective guiding and focusing to the signal of radiation longitudinal direction, ensure that antenna size subtracts
Hour can targetedly lift the radiation gain of antenna again, but can be caused if the specific size design of parasitic element is improper
Larger radiation offset, preferably selects reasonable size, the appropriate scope of the size of antenna parasitic element is in this case here
Long 1.5-2.5CM, wide 2-4mm；Preferably, the dielectric constant values scope for selecting parasitic element is 10-20.
In addition, the aperture position of void region can also produce relatively straightforward shadow to the radiation effect of antenna assembly
Ring, in attached drawing 5 as it can be seen that when the Edge Distance of 111 upper end of open area Edge Distance metal layer is less than apart from 112 lower end of metal layer
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 strengthen.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, therefore, have preferable specific aim, may be adapted to more
Kind wireless module frequency range.
The opening of metal layer can be one or two or more, and when open amount is more, the multifrequency of antenna is special
Property can be more obvious, but its radiation gain can be lost, and as making up, can pass through at least two open areas
Opening size is identical, and the radiating bands of needs can be carried out with gain superposition coupling by identical size makes up, this superposition
Coupling passes through common electromagnetic between metal layer open area and parasitic element and couples realization.The parasitic element divides metal layer
Into the shape of some slip gauges then, such as rectangle, square etc..
Referring to Fig. 4, 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, when the locus of specific automatic irrigation device is fine, which is set
It can be realized by passing through the coaxial feed mode of substrate layer, simply its occupied space can be larger compared to patch, but its
The antenna transmission characteristic and effect of acquisition have all benifits.
As the another case of embodiment, as noted previously, as metal layer in opening it is possible that multiple openings are made
Into the phenomenon of gain consume, the present invention for this defect has carried out further amendment, referring to attached drawing 4, by by parasitic element
The opening of side is cut down, so that incoherent unnecessary frequency range is weakened, reduces the consume of gain, lifting target frequency
The actual gain of section, additionally since reducing the coupling of unhelpful signal, the coupling superposition of remaining instructive signals can cause antenna
Device still has good performance to embody when close to interference source.
This antenna assembly is collectively formed by substrate layer, metal layer and parasitic element, some by setting 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 dummy section realizes the micromation of antenna assembly and the beneficial effect of high-gain.Antenna assembly manufacturer
Method technique is simple, manufacture cost is low, and the antenna impedance of manufactured automatic irrigation device is low, high gain, can effectively meet automatic
The complex environmental requirement of irrigation rig.
