Radiation characteristics and mutual coupling are the important factors to the integration design and arrangement for airborne antennas. And the study of them is significant to the EMC of airborne electronic systems. Therefore, by using UTD, a study of predicting the far field pattern of a monopole mounted on the fuselage of an aircraft is described, and the method of computing isolation between airborne antennas is referred to. Initially simple model of large airplane is given by the principle that configuration should be simplified while electromagnetic radiation characteristics should not be neglected. Furthermore, single order, two orders as well as higher orders ray tracing are discussed based on the basic modals such as cylinder, taper and flat. The analytical solution of ray tracing is given out when it exists. If the analytical solution of ray tracing doesnt exist, faster numerical searching method is recommended. Then shadow judgment is introduced briefly. Lastly programs are made, and the results are proved true by comparing them with relative references.
