The invention discloses a suspended ridge type microstrip line plane slow-wave structure which is different from a conventional suspended microstrip line slow-wave structure, a periodic metal U-shaped zigzag microstrip line is suspended, and meanwhile, a metal ridge is added to a straight line section of the microstrip line. In this way, the dielectric substrate with the surface printed with the periodic ridged metal zigzag microstrip line mainly plays a supporting role, electromagnetic waves are mainly distributed in the vacuum cavities in the upper side and the lower side of the dielectric substrate, and strong longitudinal electric field distribution is achieved above the periodic metal zigzag microstrip line. Therefore, large coupling impedance can be further obtained, and finally the interaction efficiency of the microstrip line planar traveling wave tube amplifier is improved. Taking a W-waveband slow wave structure of a U-shaped periodically suspended metal zigzag microstrip line ...
