A hybrid technique combining the method of moments with the geometrical theory of diffraction (GTD) is extended to account for the mutual coupling between antennas on a missile. The technique used to analyze polarization properties and obtain a balance between speed and accuracy is emphasized. The measured and calculated coupling between two inverted-L antennas on a missile show good agreement. It is shown that, for intermediate angular separations (100 degrees -260 degrees ), the EMI (electromagnetic interference) margin is below -15 dB, so there is no interference between the antennas on the missile. In fact, the angular separation between the inverted-L antennas mounted on the missile is 120 degrees .
