The Planar Microstrip Slow-Wave Structure for a V-band Dual-Sheet-Beam Traveling-Wave Tube

Planar microstrip slow-wave structure (SWS) consisting of two electrically connected meander lines is under study in this paper. Such SWS is suitable for millimeter-band traveling-wave tube (TWT) operating with two low-voltage sheet electron beams. The use of two beams leads to an increase in the total current while maintaining the current density and therefore leads to an improvement in the output characteristics of the device.
