Abstract

The unfeasible fabrication of helix slow wave structures in W-band traveling wave tubes makes necessary to find alternative slow wave structures in order to amplify the RF signal to the output levels required to overcome atmospheric attenuation in satellite communications. Meander lines are nowadays being studied as slow wave structures for W-band traveling wave tubes due to their favorable properties compared to full metal alternatives. A novel meander line topology is introduced in this work, showing that high gain and output power can be achieved using a low-voltage electron beam. Cold and large signal simulations are presented in this work.
