Description
Technical Field
The invention discloses an airborne forming sleeve antenna applied to an aircraft in the technical field of wireless communication.
Background
With the rapid development of the communication industry, antennas are also being continuously updated. Compared with an antenna applied to an aircraft, the electronic equipment on the aircraft is closely distributed due to the space limitation of the aircraft, so that the electromagnetic environment of the airborne antenna is very complex.
As an important component of the overall system of the aircraft, the antenna also meets aerodynamic performance requirements in addition to the electrical performance indicators meeting design requirements in the frequency range applied.
If the antenna on the aircraft meets the aerodynamic performance requirements, the antenna size is limited and cannot be too large. However, the antenna is required to meet the electrical performance design requirement, and the antenna size cannot be too small, so that the aerodynamic performance requirement of the antenna is contrary to the frequency band wavelength characteristic of the antenna.
Generally, antennas on aircrafts are mainly monopole antenna types such as a knife antenna, an inverted F antenna and the like, and although the electric performance requirements are met, the antenna is generally large in size and can influence normal flight of the aircrafts. With wider application range of the aircraft, the flying speed is gradually increased, the flying attitude is changed more and more, and the flying environment is more and more harsh. This requires a reduced number of antennas for the aircraft itself, thus reducing the antenna volume while covering a wider operating band. Therefore, research on high performance, wide frequency band and miniaturization of antennas is increasingly receiving attention.

Further, the radio frequency cable assembly is in non-contact with the metal reflecting plate.
