A slot antenna for the fuse of artillery ammunition, is provided through a sandwich
structure in which an axially divided resonator ring chamber axially enclosed between
upper and lower metallic cover discs profiled to be stable in respect of shape,
is provided with a dielectric ring disc which extends with a peripherally extending
color radially opposite a central cylindrical reflector wall through an axial slot
between the two hollow-cylindrical outside walls of the ring chamber to the outer
surface of the fuse casing which is also peripherally slit. In one of the two cover
discs the inner edge of the antenna slot which opens into the ring space is defined
by a hoop which is inserted into the front side of the outer wall and on which
connecting locations which are displaced relative to each other in the peripheral
direction are contacted through the dielectric ring disc and the axially oppositely
disposed cover disc to a circuit carrier disc, where they are brought together
in single-phase manner through a matching network to an antenna line, the second
phase of which is connected to the cover disc adjacent thereto.
