摘要 采用高低频混合技术的混合矩量法-物理光学法(MoM-PO)分析导体平台上的线天线问题;天线与平台上不规则区域采用MoM分析,平台其他部分用PO方法计算。研究了MoM区的选择对计算精度和内存需求的影响,给出了一种考虑PO区域单元间互耦的迭代方法,以此改善PO近似带来的计算误差。分析了典型载体平台上线天线问题,研究了载体上天线的阻抗和辐射特性。数值计算结果和传统MoM结果有较好的吻合。该方法在工程应用中具有较高的实用性。 This paper presents a hybrid method, which combines Physical Optics （PO） and Method of Moment （MoM） techniques, to analyze the electromagnetic properties of wire antennas mounted on or near electrically large conducting surface with arbitrary shapes. The antenna and the irregular region are divided into MoM region and the other regular and continuous regions analyzed using PO method. An iterative method is proposed to improve the accuracy by considering the coupling among the elements in the PO region. The radiation and impedance properties of wire antennas are analyzed. Numerical examples are illustrated to show the accuracy and high efficiency.
