| 摘 要： | 提出了一种角度对数周期微带曲折线慢波结构，该结构具有微带型慢波结构尺寸小、易加工的特点，同时特殊的结构使得它可以工作在极低的电压下，可用于低工作电压、宽频带毫米波径向束行波管。给出了这种慢波结构在Ka波段的色散特性和传输特性，并进行了注波互作用的分析。计算结果表明:该新型慢波结构的工作电压可低至809 V，输出功率26 W，3 dB带宽约为19 GHz (27~46 GHz)，虽然单个角度对数周期微带曲折线慢波结构的输出功率较小，但是这种结构通过功率合成，可以达到数百W的功率输出。

| Abstract: | A slow-wave structure (SWS) named micro-strip angular log-periodic meander-line is proposed for a low operating voltage vacuum amplifier. It evolves from the logarithmic spiral by cutting off a fan-shaped part and connecting the ends alternately. This letter reports the electromagnetic characteristics of this kind of SWS, and the beam-wave interaction is calculated by means of the particle-in-cell (PIC) method. From our calculation, this kind of traveling-wave tube can give 26 W output power with the 3 dB frequency range of 27-46 GHz, while the operating voltage is 809 V only. Moreover, the maximum gain and interaction efficiency are about 26.5 dB and 21.7%, respectively. Through power combination of SWSs of this kind, power of hundreds of watts can be output. |
