It is a waveguide with 4-ports which aims at sampling of microwave power. In a nutshell, directional couplers allow the determination of delivered power to the load from the power actually being transmitted by the source.

Directional coupler tends to be used for 4-port devices that are only loosely coupled – that is, only a small fraction of the input power appears at the coupled port. This arrangement, however, has the dis advantage that the load must be dis connected each time a measurement of forward power is desired, and for ward power should be measured each time frequency is changed. 방향성 결합기(Directional Coupler) (1) 결합선로 (Coupled Line) 여러분들 중에서도, 아날로그 혹은 디지털 회로에서 어떤 선로의 신호가 다른 신호선으로 전달되 버리는 현상 … Bidirectional coupler: 그냥 directional coupler 라고 한다.
