• Conformal finite-difference time domain (CFDTD) method has been deduced and implemented to compute the optimizing antenna distribution on missile-borne. Using the CFDTD and adaptive mesh generation method, the BeidDou antennas (GPS), telemetering antenna and communication antenna located in the complicated structure of the platform of missile have been simulated accurately and effectively and results have been compared with the isolation antenna. The peak direction of mail lobed changed form the center of the antenna to the center of the missile, and the isolation for antennas on the platform of missile which is less than -40 dB, therefore the distribution of the antennas system is acceptable for application.
