A waveguide directional coupler is only a directional coupler realised in a format using waveguide technology. A waveguide coupler provides a means of sampling the energy travelling within a waveguide, and as most couplers are directional in nature, sampling energy travelling in one direction, they are called waveguide directional couplers.

Waveguide couplers are available that sample the energy travelling in both directions - these are known as waveguide bi-directional couplers.
