Problems solved by technology

[0003]The traditional flying carrier antenna uses a single monopole antenna, which only has a cylindrical or rectangular columnar structure plus a plane reflection ground, and the antenna's The radome is not molded, and the disadvantages of the antenna are low structural strength, large size, and narrow bandwidth
Of course, the antenna with microstrip structure can also be used, which is more conducive to conformality, but the radiation pattern of this type of antenna often cannot meet the actual use requirements

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.

Description

technical field [0001] The invention relates to a high-strength broadband antenna suitable for flight carriers. Its typical working frequency band is an ultra-high frequency band, that is, a UHF frequency band. It has the advantages of high structural strength, wide operating frequency band, small size, and low cost. It is mainly used in identification systems and communication systems equipped on various flight carriers. Background technique [0002] At present, no matter on a civil aviation aircraft, it is generally equipped with various communication systems. Of course, these systems need to have antennas to work. These antennas are generally installed on the surface of the aircraft skin. Of course, the missile also has a communication control system, and it also needs to be equipped with an antenna to work. For this type of high-speed flight carrier, there are similar requirements for the antenna, that is, the antenna requires good structural strength, high and low tem...
