Summary of the invention
The purpose of this utility model provides a kind of broad beam circular polarized antenna, and the bandwidth of this antenna is 1500MHz～1700MHz, and can keep in communication optional position at the earth's surface.
The utility model to achieve the above object, the technical scheme of being taked is:
A kind of broad beam circular polarized antenna comprises first radiant body, second radiant body, metallic reflection plate, impedance matching part and balance fed element.
Balanced feeding spare is a λ/4 channels coaxial lines, comprises slotted line heart yearn and fluting outer conductor.In order to keep the slotted line heart yearn to be positioned at the central axis position of coaxial line, can between slotted line heart yearn and fluting outer conductor internal diameter, adopt the dieelctric sheet of annular to fix and supporting role, also can be used on and fill full medium therebetween.
First radiant body and second radiant body are that the dipole antenna of different length and oscillator arms are the bending form that has a down dip.First radiant body and second radiant body are located on the top of balanced feeding spare, and quadrature setting at grade.First radiant body, one arm links to each other with the fluting outer conductor, and another arm links to each other simultaneously with fluting outer conductor and slotted line heart yearn.Second radiant body, one arm links to each other with the fluting outer conductor, and another arm links to each other simultaneously with fluting outer conductor and slotted line heart yearn.
The impedance matching part is a kind of impedance transformer of microstrip structure, and its input port is connected with the slotted line heart yearn.
The metallic reflection plate is fixed in fluting outer conductor bottom, and in the impedance matching part together altogether.
The central axis of first radiant body, second radiant body, balanced feeding spare and metallic reflection plate coincides.
Broad beam circular polarized antenna described in the utility model also comprises radio frequency cable and radio frequency connector.Radio frequency cable one end is connected with impedance matching part delivery outlet, and the other end is connected with radio frequency connector.
The beneficial effects of the utility model
The utility model broad beam circular polarized antenna, the symmetrical structure of the central axes of employing radiant body and metallic reflection plate has the ability of comprehensive communication; Reasonably adjust radiant body and metallic reflection distance between plates, obtain bigger gain at low elevation location place, have and be similar to hemispheric broad beam.
Adopt the impedance transformer of microstrip line construction, not only convenient debugging, and also in bandwidth 1500MHz～1700MHz, standing-wave ratio is less than 1.5.The satellite communication system that can be applicable to be correlated with has covered the 1525MHz～1560MHz and the 1610MHz～1660MHz of Shu Yala satellite communication especially.

Fig. 2 is this practical broad beam circular polarized antenna plan structure schematic diagram.
Embodiment
Further specify the architectural feature of the utility model broad beam circular polarized antenna below in conjunction with accompanying drawing.
See also Fig. 1 and Fig. 2, the utility model broad beam circular polarized antenna comprises first radiant body 1, second radiant body 2, slotted line heart yearn 3, dieelctric sheet 4, metallic reflection plate 5, fluting outer conductor 6, impedance transformer 7, radio frequency cable 8 and radio frequency connector 9.
First radiant body 1 and second radiant body 2 are the bending form that has a down dip for the dipole antenna of different length and oscillator arms.First radiant body 1 and second radiant body 2 are located on the top of balanced feeding spare, and quadrature setting at grade.Wherein, balanced feeding spare is a λ/4 channels coaxial lines, comprises slotted line heart yearn 3 and fluting outer conductor 6.First radiant body, 1 one arms 11 are connected with fluting outer conductor 6, and another arm 12 links to each other simultaneously with fluting outer conductor 6 and slotted line heart yearn 3.Second radiant body, 2 one arms 21 link to each other with fluting outer conductor 6, and another arm 22 links to each other simultaneously with fluting outer conductor 6 and slotted line heart yearn 3.
First radiant body 1, second radiant body 2, slotted line heart yearn 3, metallic reflection plate 5 coincide with the central axis of fluting outer conductor 6.In order to keep slotted line heart yearn 3 to be positioned at the central axis position of coaxial line, between slotted line heart yearn 3 and fluting outer conductor 6 internal diameters, adopt the dieelctric sheet 4 of annular to fix and supporting role.
With reference to Fig. 2, first radiant body 1 is the same with the shape of second radiant body 2, and different two rectangular metallic strip of length that are rectangular shape are connected to form, and certainly, tape also can be triangle, polygon, any shape in the ellipse.
The utility model broad beam circular polarized antenna has adopted from phase structure, the length of first radiant body 1 is greater than the length of second radiant body 2,1 reactance of first radiant body is perception, 45 ° of phase lags, 2 reactance of second radiant body are capacitive, leading 45 ° of phase place, promptly first radiant body, 1 to second radiant body, 2 phase differences are 90 °.Because intrinsic 0 °, 180 ° differ between the coaxial line internal and external conductor.Four oscillators of first radiant body 1 and second radiant body 2 just differ 90 ° successively, have satisfied to form the condition of circular polarization, thereby have formed circular polarization characteristics at 1500MHz～1700MHz frequency band.
