一种L波段宽带圆波导密封窗的仿真设计

摘要

给出了一种宽带圆波导密封窗的设计方法，该方法是在密封窗的介质板和圆波导之间增加了匹配段，使得带宽变宽，可以达到30％。通过对 L 波段圆波导密封窗的仿真设计，验证了该方法的可行性。%A new method of designing broad -band circular waveguide hermetic window is proposed in this paper. This hermetic window has a matching period between dielectric -slab and circular waveguide to increase the band-width by 30%.The feasibility of this method is verified by the simulation design of L -band circular waveguide hermetic window.
