摘要
采用CST微波工作室软件,数值模拟了内外导体轴线偏心对同轴波导TEM模式性能的影响。结果表明:随着倾斜偏心度的逐渐增大,倾斜偏心同轴波导的S21参数和电场的幅值减小,但减小的幅度不是很明显,不会影响同轴波导的正常工作。但是,当偏心度增大到1°时,同轴波导TEM模式的端口电场分布云图与无偏心相比发生了很大的变化,可能导致同轴波导不能正常工作。
The effects of the misalignment between the inner-rod axis and the outer-wall axis in an open coaxial resonator are studied by the software CST microwave studio. Results show that the field amplitude and S parameter decrease with the oblique misalignment angle increase. But the effect is little, and the coaxial waveguide can work normally. While the oblique misalignment angle is 1°, the field profile of TEM mode at the coaxial waveguide＇s port is much different from the profile with very small oblique misalignment angle, the device might not work normally.
