The invention discloses a planar multi-channel slow wave structure. By processing four metal slow wave lines which have the same transmission direction, are sequentially arranged and aligned in parallel on a medium substrate, the same working voltage is simultaneously loaded, and the same electron beam is used. Among the four metal slow wave lines, the identical slow wave lines in pairs are connected in series in an end-to-end manner to form two sets of the metal slow wave lines connected in series, so that an amplified electromagnetic wave signal is returned to the start place of beam-wave interaction, namely, the position before the electron beam deceleration, and the beam-wave interaction is performed again to achieve the purpose of further amplifying the electromagnetic signal, therebysignificantly increasing the gain. At the same time, since the two sets of the metal slow wave lines connected in series operate in different frequency bands, the working bandwidth can be significantly improved without affecting the efficiency of the beam-wave interaction. Compared with the scheme using multiple traveling wave tubes, the planar multi-channel slow wave structure of the invention can greatly reduce the equipment size.
