| This article introduced the kinds and performance parameters of shortwave aircraft antenna. The theory of study shortwave aircraft antenna were discussed in detail,and combined with the structure design analysis of the empennage-caped airborne antenna of the IL76 aircraft , illuminating the development plan of the shortwave antenna for communication.To illustrate the effectiveness of the plan, we use the classical drawing software CATIA to construct 1:1 model plane, and simulate the electrical parameters of antennas by the international common software FEKO. The electrical parameters of the empennage-caped airborne antenna, such as impedance and radiation pattern are analyzed and simulated. We also describe the measurement method and request of the main antenna parameters, and carrying on the tests of real antenna. The research results comply with the given requirements, which show that this method is efficient and feasible, and can be also provided for the similar problems to be solved., and the research results have high value on engineering application. |
