Abstract
The invention relates to an air coaxial center-fed antenna which comprises an outer conductor and an inner conductor, wherein the inner conductor is coaxially arranged in the outer conductor in a penetrating manner; one end of the inner conductor is connected with an antenna feed port formed at one end of the outer conductor; the outer conductor is hollow; and the other end of the inner conductor is connected with a tightener arranged at the other end of the outer conductor. The inner conductor is coaxially arranged in the hollow outer conductor in a penetrating manner by utilizing the characteristics of low air transmission loss and dielectric coefficient, no insulating material is filled in the outer conductor, the inner conductor and the outer conductor are tightened by the tightener to be coaxial, and the diameter of the inner conductor can be increased, so that the transmission loss is reduced, and the efficiency of the antenna is improved.
Description
Technical field
The present invention relates to a kind of center-fed antenna, the coaxial center-fed antenna of specifically a kind of air.
Background technology
Common center-fed antenna is generally put in outer conductor using fine enamelled wire, and fill insulant is made impedance conversion and passed
Defeated element, but in installation and the fill insulant of fine enamelled wire, there is inner wire not coaxially, completely, inside fill insulation material
Material loss is big, causes antenna power little.
The content of the invention
For problems of the prior art, the invention provides a kind of simple structure, convenient for production, loss
It is little, the coaxial center-fed antenna of the high air of power.
The technical solution used in the present invention is：A kind of coaxial center-fed antenna of air, including outer conductor and inner wire, inner wire
Coaxially it is arranged in outer conductor, inner wire one end is connected in the antenna feed power port of outer conductor one end, its technical characterstic is institute
State hollow in outer conductor, the inner wire other end is connected in the tightener of the outer conductor other end.
Further, the outer conductor two ends difference Jing insulators connection tightener and antenna feed power port.
Further, choke is provided between the antenna feed power port of described outer conductor one end and insulator.
Yet further, the inner wire is enamel-covered wire.
The present invention utilizes the characteristics of air loss is little, dielectric coefficient is low, coaxially wears interior leading in hollow outer conductor
Body, is not filled with insulant and tenses inner and outer conductor coaxially by tightener in outer conductor, can overstriking reduction with reference to inner wire diameter
Loss and raising antenna efficiency.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
In figure：Outer conductor 1, inner wire 2, tightener 3, upper insulator 4, lower insulator 5, choke 6, antenna feed power port 7.
Specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Shown in Fig. 1, a kind of coaxial center-fed antenna of air include outer conductor 1, inner wire 2, tightener 3, upper insulator 4, under
Insulator 5, choke 6 and antenna feed power port 7.Hollow in outer conductor 1, inner wire 2 is enamel-covered wire, and inner wire 2 is coaxially arranged in
In outer conductor 1,2 one end Jing choke 6 of inner wire is connected in the antenna feed power port 7 of 1 one end of outer conductor, 1 one end of outer conductor
Lower insulator 5 is provided between choke 6, and 2 other end of inner wire is connected in the tightener 3 of 1 other end of outer conductor, leads outward
Insulator 4 is provided between the body other end and tightener 3.
