A directional coupler () comprises two hollow bodies () forming two waveguide portions. Each hollow body has an open end arranged at a first side () of the hollow body and another open end arranged at a second side () of the hollow body opposite to the first side in a longitudinal direction () of the hollow body. The hollow body has a first cross section perpendicular to the longitudinal direction. A second cross section along the longitudinal direction defines a first plane of propagation of the electric field. The two waveguide portions have a common wall along the longitudinal direction () forming a septum () between the two waveguide portions on a second plane orthogonal to the first plane. The septum has an aperture () for coupling the two waveguide portions. The aperture has a shape comprising a part () slanted with respect to the longitudinal direction.
