摘　　要：提出一种Ka频段宽带一分四功分器的结构，采用宽带波导E面T形结加波导-探针-微带过渡的结构。对E面T形结构进行改进，实现宽带功率二等分，然后两路输出通过波导双路微带探针过渡实现四路功率分配。使用三维电磁仿真软件AnsoftHFSS对该结构进行仿真优化，结果表明，在26．5～40．0GHz内，回波损耗小于-20dB，传输损耗小于0．3dB。A ka band broadband structure with one-four power divider was put forward, and the broadband waveguide E surface tee junction with waveguide-probe-microstrip transition structure was used. The E surface tee junction was improved to halve the broadband power. Then two-way output singnal went through the waveguide du- plex microstrip probe transition to realize four ways of power distributiotl. 3D electromagnetic simulation software Ansoft HFSS simulation was used for optimization of the structure. Finally the optimization resulted in return loss less than --20 dB, transmission loss less than 0.3 dE within 26.5 GHz to 40.0 GHz frequency band.
