Abstract III Abstract The radiation computation of navigation antennas and mutual coupling are the primary research contents of the integrative design of navigation antenna and electromagnetic compatibility technique. Because of the complicated constructor of the carrier and the nearby equipment cause distortions to radiation pattern, analyzing the difference is important to the optimization of antenna distribution. This paper deals with integrative technique of navigation antenna on the airborne and electromagnetic compatibility technique. The major contents are divided into three parts: The radiation computation of electrically large compound carrier, the integrative design of navigation antennas, the calculation of electromagnetic compatibility. First, several methods of electromagnetic radiation of electrically large complicated carrier are introduced, including fast multiple method which is based on method of moment, high frequency approximate method, the mixer of high-low frequency method, and prove the validity of fast multiple method; Second, the L band omni antenna and satellite navigation antenna are designed, the radiation of the above antennas in free space and airborne are compared, all parameters are tested under scaled model; The calculation of electromagnetic compatibility and the measures to improve isolation between antennas are presented at last in this paper.
