Analysis of the key technology of airborne antenna and feed equipment under complicated conditions

As the front stage of high-speed aircraft carrier of the user terminal, performance of antenna and feed equipment is directly related to the effectiveness of the wireless transceiver system datalink. This paper, from the point of view on technology application, analyzed the design methods of the antenna and feed equipment under high speed, high temperature and complex electromagnetic environment, and introduced technical features and the details about several antenna and feed equipment, such as thermal antenna, reconstruction antenna, miniaturization of controllable beam array, adaptive array antenna. The engineering application method is expounded on high-speed air craft carrier, what is of positive significance to improve the stability of data link un-der the complicated condition of flight.
