Airplane vertical tail conformal embedded short wave antenna

Abstract

The invention provides an airplane vertical tail conformal embedded short-wave antenna which is provided with an antenna body, and the antenna body is provided with a coaxial line feed double-L-shaped slot antenna structure. The double L-shaped slot antenna structures are coaxially and oppositely formed into a U-shaped slot antenna; the root part of the bottom end of the slot at the axis of the U-shaped slot antenna is connected with a feed source for feeding through a feeder line; the U-shaped slot antenna is installed in an aircraft skin interlayer on the front edge of the vertical tail of the aircraft in a wrapping mode, and the U-shaped slot antenna and the front edge of the vertical tail of the aircraft are conformally arranged. The U-shaped short-wave antenna works in the frequency band of 2MHz-30MHz, and compared with a short-wave antenna of a large aircraft in the prior art, the U-shaped short-wave antenna has the advantages of being small in size, good in performance and hidden. The front edge is conformal with the front edge of the airplane vertical empennage without influencing the aerodynamic performance of the airplane; the antenna is high in radiation efficiency, strong in communication performance and light in weight, and ensures omnidirectional radiation; and the omnidirectional and gain index requirements in the radiation direction are met.

Description

technical field [0001] The invention belongs to the technical field of aircraft radio antennas of basic electrical components, and in particular relates to a conformal embedded short-wave antenna of an aircraft vertical tail. Background technique [0002] With the rapid development of radio communication technology, antennas, as the entrance and exit of radio waves, are an indispensable part of all wireless systems. The performance of the antenna directly affects the performance of the entire wireless system. As a carrier of high-tech integration, the number and types of communication equipment on the aircraft have reached an unprecedented level. Moreover, with the increasingly complex electromagnetic environment in modern society, it becomes more difficult to achieve smooth aircraft communication, which puts higher requirements on the performance of airborne antennas. [0003] At present, airborne electronic equipment such as communication, radar, electronic countermeasur...

Problems solved by technology

[0004] However, the size of traditional aircraft short-wave antennas is generally large. Due to the limitation of aircraft dimensions, existing short-wave antennas cannot meet the communication requirements in the 2MHz to 30MHz frequency band.
