Patent ID: 7057567

Claim:
An artillery projectile fuse having a hood ( 14 ), a dielectric antenna ( 17 ) installed in said hood ( 14 ) extending transversely to a rotational longitudinal axis ( 23 ) of said fuse, said antenna being in the form of a dielectric carrier disk ( 22 ) which is electrically conductive and laminated in geometrically different areas on both sides of said disk, characterized in that, with the laminated areas ( 24 ) of the antenna ( 21 ) being laid out point-symmetrical relative to the longitudinal axis ( 23 ) for the frequency of a radar range finder at the third harmonic of a navigation satellite carrier frequency, the carrier disk ( 22 ) is positioned under the fuse hood ( 14 ) with the area ( 24 . 2 ) of a rear disk lamination of said areas ( 24 ) projecting in all directions beyond the confines of the front area ( 24 . 1 ), so as to produce an antenna ( 21 ) combined from a navigation antenna ( 19 ) and a radar antenna ( 17 ), having a hemispherical sight oriented forward in the flight direction of said fuse, wherein said combination antenna ( 21 ) is switchable alternately to a navigation receiver ( 20 ) or to a radar range finder ( 18 ) via a changeover switch ( 25 ).
