Description
Technical field
The present invention relates to the active charger of a kind of broadening miniature antenna bandwidth, belong to antenna technical field.
Background technology
Tradition intermediate waves antenna all uses the vertical ground connection element antenna in λ/4.General people commonly use loading technique to reduce this
The height of a little antennas, it is achieved the problem that the miniaturization of antenna is too high to solve intermediate waves antenna height, but load and often result in antenna
Bandwidth narrow, limit the application of intermediate waves wireless system, so carrying out the research of intermediate waves miniature antenna broadened bandwidth
It is the most necessary.
Summary of the invention
For the problems referred to above, the technical problem to be solved in the present invention is to provide the active of a kind of broadening miniature antenna bandwidth
Charger.
The active charger of a kind of broadening miniature antenna bandwidth of the present invention, it includes metal drum, metal dish, ground connection
Plate, feeding coaxial lines one, feeding coaxial lines two；The middle part of described metal dish arranges porose, and feeding coaxial lines one is worn from hole
Go out and be connected with metal drum；Feeding coaxial lines two is connected with metal dish, and distributing point is respectively at edge, inner side and the gold of metal dish
Belong to the edge, bottom of bucket；Support between metal drum with metal dish and between metal dish with earth plate with insulating support and be connected.
As preferably, described metal drum, metal dish are metal copper foil, and thickness is 5mm；
As preferably, the radius of described metal dish is 150mm, and the radius of metal drum is 50mm, metal drum a length of
260mm, metal dish is 60mm with the spacing of earth plate, and metal dish is 90mm with the spacing of metal drum.
The invention have the benefit that by increasing rosette at antenna bottom, reach broadening miniature antenna bandwidth
Purpose, easy to use, easy and simple to handle.
Accompanying drawing explanation
For ease of explanation, the present invention is embodied as and accompanying drawing is described in detail by following.
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the field pattern of the present invention.
In figure: 1-metal drum；2-metal dish；3-earth plate；4-feeding coaxial lines one；5-feeding coaxial lines two.
Detailed description of the invention
For making the object, technical solutions and advantages of the present invention of greater clarity, concrete below by shown in accompanying drawing
Embodiment describes the present invention.However, it should be understood that these describe the most exemplary, and it is not intended to limit the model of the present invention
Enclose.Additionally, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring the present invention's
Concept.
Specific embodiment one: as shown in Figure 1-2, this detailed description of the invention by the following technical solutions: it includes metal drum
1, metal dish 2, earth plate 3, feeding coaxial lines 1, feeding coaxial lines 25；The middle part of described metal dish 2 arranges porose, feedback
Electricity coaxial line 1 passes from hole and is connected with metal drum 1；Feeding coaxial lines 25 is connected with metal dish 2, and distributing point exists respectively
The edge, inner side of metal dish 2 and the edge, bottom of metal drum 1；Between metal drum 1 and metal dish 2 and metal dish and earth plate
Support with insulating support between 3 and connect.By increasing the rosette of a suitable dimension at antenna bottom, it is presented simultaneously
Electricity, thus reach the purpose of miniature antenna broadened bandwidth.
Further, described metal drum 1, metal dish 2 are metal copper foil, and thickness is 5mm；
Further, the radius of described metal dish 2 is 150mm, and the radius of metal drum 1 is 50mm, the length of metal drum 1
For 260mm, metal dish 2 is 60mm with the spacing of earth plate 3, and metal dish 2 is 90mm with the spacing of metal drum 1.
Further, adjust the phase contrast of metal dish 2 and metal drum 1 feed port, make the feed voltage phase place of metal dish 2
Fall behind the feed voltage 90 ° of metal drum 1, and the power in feed-in metal drum 1, metal dish 2 should be equal.
The dimension scale that this detailed description of the invention is used so that the resonant frequency of antenna is 129MHz, working band is
114MHz-217MHz, carries a width of 103MHz, is able to broadening.Antenna gain 4.38dB simultaneously, antenna greatest irradiation direction is along level
Face, now direction coefficient is maximum, and half-power beam width is 42.5 °.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.The technology of the industry
Personnel, it should be appreciated that the present invention is not restricted to the described embodiments, simply illustrating this described in above-described embodiment and description
The principle of invention, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and these become
Change and improvement both falls within scope of the claimed invention.Claimed scope by appending claims and
Equivalent defines.
