TL;DR: In this article, a low-voltage, high-efficiency, and wide-bandwidth W-band traveling-wave tube using a symmetric double V-shaped microstrip meander-line slow-wave structure combined with a sheet electron beam is described.

TL;DR: In this paper, the authors concentrate on the present state of study of four types of structures: helical groove, ring-plane, folded waveguide and periodically loaded waveguide, including theoretical analyses and practical applications.

TL;DR: In this paper, a high-power wideband sheet-beam coupled-cavity traveling-wave tube operating at V-band is presented, which employs three-slot doubly periodic staggered-ladder coupled-Cavity slow-wave structure, and a 5:1 aspect- ratio sheet electron beam is used to interact with the circuit.

TL;DR: In this article, the authors presented two configurations to reduce the mutual coupling (MC) between two microstrip patch antenna elements, where one ML is inserted in the slot of the ground and a maximum MC reduction of 39 dB throughout the −10 dB bandwidth is achieved.

TL;DR: In this paper, a linear theory was employed to analyze the start oscillation condition of the backward-wave oscillation in a helix traveling-wave tube (TWT) and showed that the attenuation length of the TWT decreases when the start position of the attenuator is close to the input section of the slow wave structure (SWS).
