摘　　要：高功率、宽频带是当前科研人员研究行波管的主流方向,中国工信部最新规定E波段的频率范围在71-76 GHz/81-86 GHz。虽然传统的环圈慢波结构有更高的互作用阻抗,但是当其达到E波段及以上由于其结构特点在现实中难以加工,所以难以实现工作在E波段,为了提升输出功率,本文设计了E波段矩形环对角双杆慢波结构行波管的研究,对其进行注波互作用模拟仿真和计算,带状电子注采用19.1 kV的电压,电流为0.14 A的条件下,行波管可获得最大400 W的瞬时输出功率,增益为46.02 dB、电子效率15%。High power and wide bandwidth are currently the mainstream research directions for researchers studying traveling-wave tubes.The latest regulations from the Ministry of Industry and Information Technology in China specify the frequency range of the E-band as$71-76 GHz/81-86 GHz.$Although traditional ring-loop slow-wave structures have higher interaction impedance,they become challenging to process in practical applications when reaching the E-band and above due to their structural characteristics,making it difficult to operate in the E-band.In order to increase the output power,this study focuses on the research of a rectangular ring vertex double bar slow-wave structure traveling-wave tube in the E-band.Simulation and calculation of the interaction between the beam and wave were conducted.With an electron beam voltage of 19.1 kV and a current of 0.14 A,the traveling-wave tube achieved a maximum instantaneous output power of 400 W,with a gain of 46.02 dB and electron efficiency of 15%.
