In a word we can see from that although inverted trapezoid ridge waveguide has bigger attenuation constant it has bigger power capacity .

由此可见 倒梯形 脊波导虽然具有相对较大的衰减常数，但同时也具有很大的功率容量，因此可作为一种优良的微波传输线。

Rectangular ridge waveguide has the smallest single-mode bandwidth which makes it suits for the filtering system . Trapezoid double ridge waveguide is more suitable for transmission of microwave information .

矩形脊波导单模带宽最小，适用于滤波系统， 梯形 脊波导衰减常数最小适合于微波信息传输。

By comparing the data we can see that inverted trapezoid ridge waveguide has the biggest cutoff wavelength and single-mode bandwidth it is more conducive to miniaturization devices design of microwave .

通过对比数据可得到： 倒梯形 双 脊波导截止波长和单模带宽最大，适用于小型化微波器件。
