摘要：

In this paper, a compact and broadband directional multi-aperture waveguide coupler was initially designed for terahertz sheet beam travelling wave tubes. The proposed coupler is based on a series of identical apertures distributed between a pair of parallel rectangular waveguides. Simulation results predicted that the bandwidth for the coupling coefficient greater than -1 dB was 81.3 GHz (220.0-301.3 GHz), corresponding to a fractional bandwidth of 31.2% Meanwhile, the reflection of all ports was lower than -15 dB, and the maximum isolation coefficient was below -15 dB.
