For miniaturized vacuum-tube electron devices at millimeter and submillimeter (THz) bands, the possibility of low-voltage operation is of primary importance. Planar slow-wave structures (SWS) on dielectric substrates are favorable for the low-voltage operation. In this paper, we discuss design, fabrication and cold test of millimeter-wave planar SWSs. We consider the microstrip meander-line SWSs, which are designed for operation in traveling-wave tube power amplifiers with sheet electron beam.
