Problems solved by technology

[0002] Ordinary center-fed antennas usually use fine enameled wires to be placed in the outer conductor, filled with insulating materials as impedance transformation and transmission elements, but when installing fine enameled wires and filling insulating materials, there are inner conductors that are not coaxial, complete, and filled with insulating materials. Large transmission loss, resulting in low antenna power

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 [0001] The invention relates to a center-fed antenna, in particular to an air coaxial center-fed antenna. Background technique [0002] Ordinary center-fed antennas usually use fine enameled wires to be placed in the outer conductor, filled with insulating materials as impedance transformation and transmission elements, but when installing fine enameled wires and filling insulating materials, there are inner conductors that are not coaxial, complete, and filled with insulating materials. The transmission loss is large, resulting in low antenna power. Contents of the invention [0003] Aiming at the problems existing in the prior art, the invention provides an air coaxial center-fed antenna with simple structure, convenient production, small transmission loss and high power. [0004] The technical solution adopted in the present invention is: an air coaxial mid-fed antenna, including an outer conductor and an inner conductor, the inner conductor is coaxiall...
