摘　　要：场分析法能够有效的计算出加载滤波器单间隙输出回路间隙阻抗的实部。设计了同轴单间隙TM410模输出腔的结构。由场分析法模拟计算和分析了矩形波导长度和波导内膜片间距对间隙阻抗的影响。在谐振腔结构参数一定时,波导长度的改变对间隙阻抗没有影响,而膜片间距的改变对间隙阻抗有较大的影响。Field analysis method can effectively calculate the real component of single gap impedance in output circuit loaded filter. The structure of single gap output coaxial cavity in which TM410 works is designed. Impact of rectangular waveguide length and its diaphragm spacing on the gap impedance are simulated,calculated and analyzed using field analysis method. When cavity structure parameters remain the same,the length of the waveguide has no impact on the gap impedance, however, the spacing of diaphragm change has a larger effect on the gap impedance.
