Abstract
The invention discloses a strong-strength broadband antenna for a flying carrier, which comprises a metallic reflective ground with a central hole. A solid antenna housing is connected to the metallic reflective ground. A radiation oscillator is embedded in the solid antenna housing, and comprises a columnar monopole metallic oscillator on which at least one side wing is arranged. The columnar monopole metallic oscillator is extended from the interior of the solid antenna housing, and passes through the central hole on the metallic reflective ground until reaching the outside of the solid antenna housing. The part, exposed outside the solid antenna housing, of the columnar monopole metallic oscillator is connected with an N terminal. The preparation process of the strong-strength broadband antenna for the flying carrier comprises the following specific steps of: reserving a mould according to the solid antenna housing and the reflective ground structure of the antenna, arranging the reflective ground and radiation oscillator of the antenna in the mould, simultaneously injecting a fluidic solid antenna housing dielectric material into the mould through a small hole, performing cooling after the whole mould is filled with the material, and finally removing the mould to obtain the integrated antenna.

NHead.
The preparation technology of a kind of strong-strength broadband antenna for flying carrier of the present invention, concrete steps are as follows: at first offer mould according to solid radome and antenna-reflected ground structure, antenna-reflected ground, aerial radiation oscillator are positioned in the mould, on mould, inject the solid radome dielectric material of flow-like by aperture simultaneously, after material is filled with whole mould, cool off, remove at last mould and namely obtain integral antenna.
Compared with prior art, the present invention has following advantage:
The aerial radiation part is by cylindrical or rectangle one pole metal oscillator among the present invention
5Consist of, and have flank at this oscillator flank, both can only in a side flank be arranged, a flank is perhaps respectively arranged in both sides respectively, perhaps have a plurality of flanks in both sides
1With
6, the structure of flank can be triangle body, cuboid, prismatoid etc., and this flank structure and oscillator are integrated, consist of radiating doublet, and it not only can improve bandwidth, the gain of antenna, has also strengthened the antenna overall construction intensity simultaneously;
Adopt metallic reflection ground
2, can offer the connecting hole of the shapes such as single or a plurality of rectangles, ellipse in mesopore both sides, metallic reflection ground
7, when this preparation was invented, this structure can make the solid radome medium fluid of high temperature directly flow to metallic reflection ground
