Description
Technical field
It the utility model is related to a kind of antenna of the monitoring node of wireless sensor network.
Background technology
For the monitoring node of wireless sensor network, antenna is highly important.Because the use of reality needs, monitoring
Node develops to small volume, the direction that working frequency is high, integrated level is high always, therefore when design node antenna, both
Consider these features, while also to focus on the performance of antenna, and microstrip antenna has small volume, in light weight, low complexity
Degree, cost are low, and working frequency is can be in 100MHz ~ 5GHz the advantages that, so being obtained increasingly in various mini-plants
It is widely applied, but after existing microstrip antenna is made using printed microstrip line, is easily caused antenna imbalance.
The content of the invention
The technical problems to be solved in the utility model is：A kind of antenna of the monitoring node of wireless sensor network is provided,
To solve above-mentioned problems of the prior art.
The technical scheme that the utility model is taken is：A kind of antenna of the monitoring node of wireless sensor network, including day
Line arm, microstrip feed line, microstrip balun line and earth plate, antenna arm, microstrip balun line and earth plate are arranged at medium substrate bottom
Layer, antenna arm are connected to earth plate by microstrip balun line, and microstrip feed line is arranged on medium substrate top layer, and microstrip feed line passes through Jie
Through hole is electrically connected to microstrip balun line on matter substrate.
Antenna arm includes the epoxy resin fiberglass layer composition of two copper foil layers and two copper foil interlayers, antenna arm composition material
Thickness be followed successively by 0.018mm, 0.8mm and 0.018mm.
The beneficial effects of the utility model：Compared with prior art, the utility model concatenates micro-strip bar on microstrip feed line
Human relations line, by microstrip balun line, antenna imbalance-balance conversion is realized, ensures the incentive equilibrium of dipole antenna, this practicality is newly
Type also has the characteristics of simple in construction, cost is low, convenient operation and control is quick.

Embodiment
Below in conjunction with the accompanying drawings and the utility model is described further specific embodiment.
Embodiment 1：As Figure 1-Figure 4, a kind of antenna of the monitoring node of wireless sensor network, including antenna arm 1,
Microstrip feed line 2, microstrip balun line 3 and earth plate 4, antenna arm 1, microstrip balun line 3 and earth plate 4 are arranged at medium substrate 5
Bottom, antenna arm 1 are connected to earth plate 4 by microstrip balun line 3, and microstrip feed line 2 is arranged on the top layer of medium substrate 5, micro-strip feedback
Line 2 is electrically connected to microstrip balun line 3 by through hole 6 on medium substrate 5.
Preferably, above-mentioned antenna arm 1 includes the epoxy resin fiberglass layer of two copper foil layers and two copper foil interlayers（FR4 layers）
Composition, the thickness of the composition material of antenna arm 1 are followed successively by 0.018mm, 0.8mm and 0.018mm.
From common epoxy resin fiberglass（FR4）As the medium substrate of antenna, its thickness H=0.8mm, relatively
Dielectric constant=0.46, loss tangent value=0.018, in thickness h=0.018m of substrate upper and lower surface microstrip line, its conductance E
= s/m。
It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art can readily occur in change in the technical scope that the utility model discloses
Or replace, it should all cover within the scope of protection of the utility model, therefore, the scope of protection of the utility model should be with the power
The protection domain that profit requires is defined.
