Abstract :
We discuss the design and implementation of a waveguide coupler for a sheet-beam coupled-cavity structure. Discussion includes excitation of the fundamental mode with low VSWR, wide bandwidth, circuit sensitivity, and tuning. We conclude with a comparison with round-beam structure, and experimental results of sheet beam coupler.
