The circular polarized antenna that one embodiment provides, is used for receiving satellite-signal.Wherein, satellite-signal be gps satellite signal,
Big Dipper satellite signal or other can carry out the satellite-signal that positions.Meanwhile, this circular polarized antenna is for traditional ceramic antenna
Having made to improve in configuration aspects, concrete principle is as follows.
As shown in Figure 1 to Figure 3, this circular polarized antenna includes radiating layer 100, dielectric layer 200 and reflecting layer 300.Wherein, spoke
Penetrate layer 100 and reflecting layer 300 lays respectively at the both sides of dielectric layer 200.Radiating layer 100 is used for radiating and receiving circularly polarised wave, with
Time can be finely adjusted to adapt to the requirement of this satellite-signal for different types of satellite-signal.Reflecting layer 300 is used for reducing
Reflected signal, suppresses multipath, thus improves certainty of measurement and receiving sensitivity.
Wherein, the material in reflecting layer 300 is Copper Foil.The material of dielectric layer 200 is PCB substrate, and its dielectric constant is between 4.0
Between 5.0.Wherein, PCB substrate can be paper base plate, epoxy glass-fiber-fabric substrate, composite base plate, specific substrate or other classes
Type.The material of radiating layer 100 is similarly Copper Foil, and radiating layer 100 be shaped as square such that it is able to improve and uniformly receive star
Effect.Therefore, the circular polarized antenna in the present embodiment is PCB dual platen.Based on above-mentioned characteristic, as shown in Figure 4, in reflecting layer
Low noise signaling module 400 can be set on 300.Wherein, low noise signaling module 400 refers to be amplified by signal and filter
Circuit.
It addition, radiating layer 100 is provided with radiating doublet 110, feed point 120 and degeneracy isolating construction.Wherein, radiating doublet 110
For being made up of Copper Foil, it can produce the first degenerate mode and the second degenerate mode.Meanwhile, the first degenerate mode and the second degenerate mode are

Wherein, second phase debugging unit 132, third phase debugging unit 133 are respectively radiating layer 100 from other two
The part that the edge that bar is parallel to each other is formed after starting inwardly to carve, therefore second phase debugging unit 132 and third phase
Position debugging unit 133 is same without electric current.Meanwhile, between second phase debugging unit 132 and third phase debugging unit 133
It is not communicated with.The area of second phase debugging unit 132 and third phase debugging unit 133 is all higher than first phase debugging unit
131。
Second phase debugging unit 132 and third phase debugging unit 133 are for by along second area 160 and to radiation
The center position of layer 100 carries out the mode carved, and the phase place controlling circular polarized antenna is rotated in a clockwise direction, though this entelechy
Change the impedance deflection capacitive of antenna, consequently facilitating carry out the debugging of impedance matching.Wherein, second area 160 is perpendicular to the firstth district
Territory 150.As it is shown in figure 9, after second phase debugging unit 132 and third phase debugging unit 133 are carved accordingly, this circle
The impedance phase of poliarizing antenna is rotated in a clockwise direction.
Meanwhile, in the present embodiment, first phase debugging unit 131, second phase debugging unit 132, third phase are adjusted
Examination unit 133 and feed point 120 make the impedance of this circular polarized antenna be 50 Europe jointly, thus impedance matching.Simultaneously for other classes
For the satellite-signal of type, only first phase debugging unit 131, second phase debugging unit 132 and third phase need to be debugged
Unit 133 is finely adjusted the impedance of i.e. this circular polarized antenna of scalable so that impedance matching.
It is understood that circular polarized antenna is not limited to above-mentioned a kind of situation about the structure regulating impedance, as long as finally
Make the impedance matching of circular polarized antenna.
Concrete, as it is shown in figure 5, degeneracy isolating construction also includes first frequency debugging unit 134 and second frequency debugging
Unit 135.First frequency debugging unit 134 and second frequency debugging unit 135 all include some lines of rabbet joint being parallel to each other.With
Time, do not connect between each line of rabbet joint in first frequency debugging unit 134, and be perpendicular to the diagonal residing for the first degenerate mode.The
Do not connect between each line of rabbet joint in two frequency debugging units 135, and be perpendicular to the diagonal residing for the second degenerate mode.Cause
This, the present embodiment by arranging first frequency debugging unit 134 and second frequency debugging unit 135, make the first degenerate mode, second
The current path of degenerate mode is snakelike cabling, increases current path, consequently facilitating regulation the first degenerate mode, the second degenerate mode
Between phase contrast, and the mid frequency of this circular polarized antenna is adjusted to the frequency of respective satellite signal.
Wherein, first frequency debugging unit 134 enters for being perpendicular to cornerwise direction residing for the first degenerate mode by edge
The mode of row cutting seam, extends the current path 111 of the first degenerate mode, i.e. becomes snakelike cabling, make the first degenerate mode
Frequency compares the frequency before fine setting to low frequency offset, so that circular polarisation resonance circle diminishes, and then corresponding reduces whole circular polarisation
The mid frequency of antenna.As shown in Figure 10, after first frequency debugging unit 134 cutting is stitched, the first degenerate mode (i.e. fL) frequency
Rate reduces.
Second frequency debugging unit 135 is for by along being perpendicular to cutting seam in cornerwise direction residing for the second degenerate mode
Mode, extends the current path 112 of the second degenerate mode, i.e. becomes snakelike cabling, make the frequency of the second degenerate mode compare micro-
Frequency before tune is to low frequency offset, so that circular polarisation resonance circle diminishes, also reduces the center frequency of whole circular polarized antenna simultaneously
Rate.As shown in figure 11, after second frequency debugging unit 135 cutting is stitched, the second degenerate mode (i.e. fH) frequency reduce.
It addition, degeneracy isolating construction also includes the 3rd frequency debugging unit 136 and the 4th frequency debugging unit 137.Wherein,
3rd frequency debugging unit 136 for by the way of carrying out rescinded angle along direction cornerwise residing for the first degenerate mode, improves the
The frequency of one degenerate mode.3rd frequency debugging unit 136 lays respectively at cornerwise two ends residing for the first degenerate mode.Meanwhile, exist
Keep rescinded angle to be shaped as isosceles triangle when carrying out rescinded angle as far as possible, and the rescinded angle size at two ends keeps consistent.Owing to rescinded angle can make
The current path 111 of the first degenerate mode shortens, and improves the frequency of the first degenerate mode the most accordingly, so that circular polarisation resonance circle becomes
Greatly, the mid frequency of circular polarized antenna and then is improved accordingly.As shown in figure 12, after the 3rd frequency debugging unit 136 rescinded angle, the
One degenerate mode (i.e. fL) frequency raise.
4th frequency debugging unit 137 is for by the side carrying out rescinded angle along direction cornerwise residing for the second degenerate mode
Formula, improves the frequency of the second degenerate mode.Wherein, the 4th frequency debugging unit 137 lays respectively at diagonal residing for the second degenerate mode
Two ends.Meanwhile, keep when carrying out rescinded angle rescinded angle to be shaped as isosceles triangle as far as possible, and the rescinded angle size at two ends keeps one
Cause.Owing to rescinded angle can make the current path 112 of the second degenerate mode shorten, improve the frequency of the second degenerate mode the most accordingly, thus
Circular polarisation resonance circle is made to become big, and then the corresponding mid frequency improving circular polarized antenna.As shown in figure 13, to the 4th frequency debugging
After unit 137 rescinded angle, the second degenerate mode (i.e. fH) frequency raise.
In the present embodiment, at first frequency debugging unit 134, second frequency debugging unit the 135, the 3rd frequency debugging unit
