Multi-Hole Waveguide Coupler

Multi-hole waveguide coupler is extension of single-hole coupler, designed to increase the operational bandwidth. The performance is based on size of the coupling holes and distance between them, since it is important to achieve wave amplification in the through-direction and cancellation in the opposite…
