摘要： A directional waveguide coupler (20) has four input ports and four output ports. Each input port is coupled to each of the output ports. The directional coupler (20) includes a first coupler having two waveguides (W1, W2) coupled to each other by a first slot array (S1), defined in a first wall (21) common to the two waveguides (W1, W2) of the first coupler. A second coupler has two waveguides (W3, W4), coupled to each other by a second slot array (S2), defined in a second wall (22) common to the two waveguides (W3, W4) of the second coupler. The first and second slot arrays (S1, S2) lie on a first common plane. The first and second couplers are coupled to each other by a third slot array (S3) and a fourth slot array (S4), which lie on a second common plane perpendicular to the first common plane.
