A novel planar slow wave structure (SWS) for traveling wave tube (TWT) is proposed. The major advantage of the planar architecture is its easy realization with respect to the typical 3-D SWSs. The particle in cell simulations of the TWT show an achievable gain up to 36.4 dB and a maximum output power of 17.4 W for an operating frequency of 92 GHz. The planar structure can be realized using the standard photolithographic techniques, which improve the reproducibility and performance.
