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％.
