In a two-armed directional coupler, consisting of a conductor ring (5) and four connecting arms (1, 2, 3, 4), emerging radially therefrom, all the conductor trains are designed as slotted conductors. In this case, the connecting arms (1, 2, 3, 4) are connected to the conductor ring (5) by means of T-junctions (Fig. 1). <IMAGE>
