摘　　要：本文为解决纵向偏磁铁氧体H波导相移问题,推导出了适合LsM和LsE模的耦合波方程组。讨论了H波导的双模耦合,得出了主模的相移常数β随偏磁变化的公式和曲线,为设计铁氧体H波导移相器和铁氧体单体相扫天线提供了理论基础。在分析主模特性的基础上,提出了一种新型天线结构,并求出辐射场。实验证明,理论结果与实验基本一致。For solving the question of ferrite H-wavequide phase shift applyed longitudinal magnetic field, the coupling wave equations which fit LSM modes and LSE modes used in this thesis. The thesis analyses two mode coupling in the H-wavequide, and derives the formulas and the curves for the phase constant of the main mode which changes as the applyed magnetic field changes. It lays down theory foundation for design ferrite H - wavequide phase shifter and ferrite single body phase scanning antenna. In the analysis of main mode characteristics we find a new structure antenna and resolve it's radiation field. The trial result shows that the deduced theory consists with the result basically.
