1. A disc-shaped slot antenna ( 17 ) arranged transversely with respect to the longitudinal axis ( 18 ) concentrically in a conical artillery fuse ( 11 ), characterised in that it has a resonator ring chamber ( 28 ) which is divided transversely with respect to the longitudinal axis ( 18 ) and which in radially opposite relationship to a central cylindrical reflector wall opens with a radially peripherally extending antenna slot ( 13 ′) through the conical casing surface of the fuse ( 11 ) and into which is inserted a ring disc ( 29 ) of dielectric material having a collar ( 30 ) extending therearound in a flange-like configuration, of an axial thickness which is markedly smaller than the ring disc ( 29 ), the collar extending radially through the slot ( 13 ′), filling same, as far as the conical casing surface.
