| 摘 要： | 研究了一种新型高功率微波相移器同轴插板式相移器，其设计思想为：在同轴波导内插入金属导体板，将同轴波导分为几个扇形截面波导，由于扇形截面波导中传输的TE11模相速度与同轴TEM模的相速度不同，通过改变插入金属板的长度就可以实现相移的调节。设计了中心频率为4 GHz的同轴插板式相移器，并进行了数值模拟验证。结果表明：当相移器同轴波导内半径为2.0 cm，外半径为4.5 cm，相移器总长度为50 cm时，可实现的最大相移量为360°，在3.9~4.1 GHz频率范围内相移器的插入损耗低于0.1 dB。

| Abstract: | A novel phase shifter for high power microwave is described and analyzed. The coaxial TEM mode is converted to TE_(11) fan-shaped waveguide mode by inserting fins into the coaxial waveguide.The phase shift changes with varying the length of the fins. A phase shifter for 4 GHz based on this principle is designed and optimized. The calculated results show that the maximum phase shift is 360° when the length of the phase shifter is 50 cm, the inner radius 2.0 cm and outer radius 4.5 cm, and the loss is below 0.1 dB in the range of 3.9~4.1 GHz. The input and output of phase shifter are co-aligned on the same axis. |
