摘　　要：用微波网络方法讨论了宽频带槽波导定向耦合器的分析和设计问题.使用部分介质填充非对称双槽波导的横向等效网络,编制了相应求解程序.计算表明,本文设计的两种3mm波段耦合器的相对带宽都在24%以上,是常规的对称双槽波导耦合器带宽的5倍,而它们的长度却比文献中已有的设计都大为缩短.The problems of analysis and design of the broadband groove guide directional couplers are investigated by the microwave network method. Using the transverse equiva- lent network for partially dielectric-filled asymmetrical double-groove guide, a related program for solving the problems is developed. The calculations show that the relative bandwidths of the couplers given in this paper are all larger than 24%, which is five times as many as the bandwidth of the conventionally designed groove guide couplers; whereas the lengths of the present couplers are much shorter than those designed in the references.
