摘　　要：设计了一种结构简单,容易制造的开槽波导功率分配器/合成器。该合成器采用锥形微带线-波导的过渡结构,每路微带线传输部分由小腔体进行隔离。通过CST仿真软件,设计了一个中心频率为35GHz的Ka频段的功率合成器。仿真结果显示,该结构回波损耗小于-20dB时的带宽达近500MHz,且插入损耗小于0.1dB。可见,具有极低的插入损耗和较低的回波损耗。A slotted-waveguide power divider/combiner,whose structure is simple,and which is easy to be produced,has been designed.The transition structure of cone-shape microstrip-waveguide was adopted in the combiner.The transmission sections of every microstrip are isolated with each other by small cavities.A Ka-band power combiner with frequency at 35 GHz was designed with CST simulation software.The simulation result indicates that the bandwidth with less than-20 dB return loss approximates to 500 MHz and the insertion loss is less than 0.1 db.
