ACCURATE OPTIMIZATION DESIGN OF MILLIMETER WAVE DIPLEXERS 

把改进遗传算法用于高性能毫米波双工器的优化设计 .双工器采用 H-面 T-型结构和 E-面膜片波导滤波器 .用该方法设计了 3只不同频段的双工器 ,并设计加工了 1只毫米波波段的双工器 ,设计结果和实验数据吻合较好 ,证明了这种算法的精确性和有效性 .

The improved genetic algorithm was applied to the optimization design of high performance millimeter wave diplexers. The waveguide H plane junctions and the E plane septum filters were used for designing the diplexers. The genetic algorithm was used to optimize the diplexer including optimizing the filters and the structural parameters of the diplexer itself. Three diplexers of different frequency bands were designed accoding to this method.One diplexer of millimeter wave band was designed and fabricated. The agreement between the theoretical and the experimental results of a millimeter wave diplexer proved the accuracy and validity of the genetic algorithm.
