【Abstract】 A new hybrid technique for calculating the scattering of an electrically large conducting body by microstrip antennas on its surface is presented. The high-frequency and the low-frequency methods are combined via the equivalence theorem. This technique overcomes the shortcomings of the existing methods and can apply to concave large conducting bodies by introducing SBR or IPO. Some numerical results have been obtained, demonstrating the accuracy, efficiency and capability of the technique.更多还原
