摘　　要：采用一致性几何绕射理论 (U TD)结合互易定理准确分析了复杂电大导体表面上缝隙天线间的互耦。U TD是高频方法 ,对于解决电大系统问题十分有效。本文用 U TD方法计算了电大导体圆柱面上缝隙天线间的互耦 ,与已有文献结果吻合得很好 ,对实际工程有一定的指导意义。The Uniformgeometrical Theory of Diffraction (UTD) is employed to accurately analyze the coupling between slot antennas on complex electrically large conductive surface combined with reciprocity theorem UTD is a kind of high frequency method and it can efficiently solve the problem of electrically large object The coupling between slot antennas is computed with the influence of the electrically large cylindrical surface being considered The results obtained in good agreement with those in the available literature and useful for practical projects

关 键 词：一致性几何绕射理论 互易定理 互耦 缝隙天线
