Abstract: A miniature planar meander-type slow-wave structure (SWS) for a $W$-band traveling-wave tube is studied. Computer simulation of the SWS electrodynamic parameters is performed. A new technology for fabrication of planar microstrip SWSs with the aid of laser ablation is proposed. The $S$-parameters of the SWS are experimentally studied. The experimental data are in good agreement with the results of the 3D computer simulation. Output characteristics of the traveling-wave tube with a sheet electron beam and planar SWS are calculated.

Keywords: traveling wave tube, meander line, slow-wave structure, dielectric substrate.
