文中运用格林函数法设计出切比雪夫渐变脊波导,采用数值方法对理论设计进行实例验证,并利用微波工作室对设计结果进行了瞬态分析,实验表明在40%的带宽内,其驻波系数小于1.1。作为输能装置,这种脊波导具有渐变长度短、匹配特性好、工作频带宽、驻波系数小等优点,并已经应用于C波段前向波放大管。
In this paper, the Chebyshev gradient ridge waveguide is designed by using Green’s function method. The theoretical design is verified by numerical method. The transient results of the design are analyzed by using a microwave studio. The experiment shows that within 40% of the bandwidth, The coefficient is less than 1.1. As a power transmission device, the ridge waveguide has the advantages of short gradation length, good matching characteristic, wide working frequency band and small standing wave coefficient, and has been applied to a C-band forward wave amplifier tube.
