The gain and the efficiency are greatly improved. Under the condition that the signal quality is greatly improved, the antenna area is not enlarged, processing and manufacturing cost is effectively saved, and the circularly-polarized panel antenna is more favourable for installing and carrying.
Description
Technical field
The present invention relates to a kind of plate aerial, relate in particular to a kind of circular plate antenna.
Background technology
At present, plate aerial is little, easy to carry with its volume, efficient and gain advantage of higher are subjected to using widely, is particularly useful for dealing with accidents such as weather, terror.
Plate aerial comprises radiating layer, feeding network etc., and radiating layer is provided with radiator, and feeding network is provided with resonant cavity etc.
The back side of the radiating layer of plate aerial of the prior art as shown in Figure 1, radiator is the slit towards an end of feeding network; The front as shown in Figure 2, the outside end of radiator is a strip.Feeding network is the feeding network of linear polarization plate aerial.
There is following shortcoming at least in above-mentioned prior art:
, poor signal quality low to the gain that the satellite-signal of circular polarization receives, efficient are low.
Summary of the invention
The purpose of this invention is to provide a kind of height that gains, signal quality is strong, efficient is high circular plate antenna.
The objective of the invention is to be achieved through the following technical solutions:
Circular plate antenna of the present invention, comprise radiating layer, feeding network, described radiating layer is provided with radiator, and described feeding network is the feeding network of linear polarization plate aerial, described radiator is the slit to an end of described feeding network, and the outside end of described radiator is a circular hole.
As seen from the above technical solution provided by the invention, circular plate antenna of the present invention, because radiator is the slit to an end of the feeding network of linear polarization plate aerial, the outside end of radiator is a circular hole.Gain and efficient are promoted greatly, improve under a lot of situations at signal quality, antenna area does not enlarge, and has effectively saved the cost of processing and manufacturing, is more conducive to install and carry.

Among the figure: 1, slit, 2, circular hole, 3, oscillator.
Embodiment
Circular plate antenna of the present invention, its preferable embodiment as shown in Figure 3, comprise radiating layer, feeding network, described radiating layer is provided with radiator, described feeding network is the feeding network of linear polarization plate aerial, described radiator is slit shown in Figure 1 to an end of feeding network, and an outside end is a circular hole shown in Figure 3.
The concrete inside end of each described radiator can be provided with 4 slits, the corresponding circular hole in each bar slit.
The outside end of described radiator can be provided with oscillator.
As shown in Figure 4, described oscillator can be criss-cross electric conductor, and each circular hole can corresponding oscillator.
Described criss-cross electric conductor comprises two limits that intersect vertically, every limit all with described slit layout at 45.
In described two limits that intersect vertically, one is broadside, and another is narrow limit, and described relatively slit, described narrow limit is tilted to the left 45 °, and described relatively slit, perhaps described narrow limit is tilted to the right 45 °.
Described relatively slit, described two limits that intersect vertically half-twist to the left or to the right can be carried out the change of left-handed or dextrorotation to the polarization of antenna.
Described oscillator can be arranged on the dielectric film, and described dielectric film is attached on the outside one side of described radiating layer.
Because of satellite-signal is to launch earthward in the wave beam mode of round screw thread line, the present invention is at first with the rectangular circular hole that changes into of the outside end of original radiator, so that consistent with the wave beam mode of satellite-signal;
Secondly on circular hole, enclose the film of one deck band crosswise (with angle at 45, the slit of the other end), be to be the feeding classification of original linear polarized antenna because feeding network of array antennas adopts, by such crosswise circular beam is decomposed into vertical and horizontal beam, and only the time with angle at 45, slit, decomposition that could circular beam is complete, and can not lose signal.Signal after decomposing like this can be consistent with the wave beam mode of antenna after entering feeding network of array antennas, thereby reach the effect of not losing signal strength signal intensity.The antenna gain that the process said method is transformed out is than using the linear polarized antenna with homalographic to improve 3 dB when receiving circularly polarized signal.Effectively raise antenna efficiency and antenna gain, and promoted the aerial signal quality of reception
The present invention changes into circular plate antenna with the linear polarization plate aerial, and radiator from the rectangular circle that becomes, and is increased one deck oscillator, and oscillator is the form of cross, places with angle at 45, slit.And can be tilted to the left or be tilted to the right by changing the position of oscillator, can carry out left-handed and variation dextrorotation to polarization.
With the situation of linear polarization plate aerial with homalographic under, gain will improve 3 dB, efficient promotes greatly.Improve under a lot of situations at signal quality, antenna area does not enlarge.Effectively saved the cost of processing and manufacturing, be more conducive to install and carry.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.
