Abstract Isolation between antennas is an important index for electromagnetic compatibility (EMC) on airborne platform. Airborne platform is an electrically large object and it is difficult to analyze the isolation between antennas mounted on it only by using the Method of Moment (MoM). The Uniform geometrical Theory of Diffraction (UTD) is a kind of high frequency method and can analyze electrically large objects, however, it has poor accuracy. The hybrid MoM-UTD method is employed to analyze the isolation between antennas on airborne platform. Both accuracy and computing speed are concerned, and the numerical results agree well with the measurements.
