Abstract
The utility model relates to the coaxial center-fed antenna of a kind of air, comprise outer conductor and inner wire, inner wire is coaxially arranged in outer conductor, inner wire one end is connected in the antenna feed mouth of outer conductor one end, hollow in described outer conductor, the inner wire other end is connected in the wire grip of the outer conductor other end.Utilize the feature that air transmission loss is little, dielectric coefficient is low, coaxially inner wire is worn in hollow outer conductor, not fill insulant to strain inner and outer conductor by wire grip coaxial in outer conductor, overstriking can reduce loss and improves antenna efficiency in conjunction with inner wire diameter.
Description
Technical field
The utility model relates to a kind of center-fed antenna, is the coaxial center-fed antenna of a kind of air specifically.
Background technology
Common center-fed antenna adopts fine enamelled wire to put into outer conductor usually, fill insulant makes impedance transformation and transfer element, but when the installation of fine enamelled wire and fill insulant, there is inner wire disalignment, completely, inside fill insulating material loss large, cause antenna power little.
Summary of the invention
For problems of the prior art, the utility model provides that a kind of structure is simple, convenient for production, loss is little, the coaxial center-fed antenna of the air that power is high.
The technical solution adopted in the utility model is: the coaxial center-fed antenna of a kind of air, comprise outer conductor and inner wire, inner wire is coaxially arranged in outer conductor, inner wire one end is connected in the antenna feed mouth of outer conductor one end, its technical characterstic is hollow in described outer conductor, and the inner wire other end is connected in the wire grip of the outer conductor other end.
Further, described outer conductor two ends are respectively through insulation sub-connection wire grip and antenna feed mouth.
Further, choke is provided with between the antenna feed mouth of described outer conductor one end and insulator.
Again further, described inner wire is enamelled wire.
The present invention utilizes the feature that air transmission loss is little, dielectric coefficient is low, coaxially inner wire is worn in hollow outer conductor, not fill insulant to strain inner and outer conductor by wire grip coaxial in outer conductor, overstriking can reduce loss and improves antenna efficiency in conjunction with inner wire diameter.
Accompanying drawing explanation
