ABSTRACT:
An antenna for an electronic projectile detonator. A desired antenna pattern which is rotationally symmetrical to the longitudinal axis of the projectile is produced by designing the antenna as a dipole which is fed via a coaxial line and which is decoupled from the feeder line by a .lambda./4 wave trap. The dipole is realized by a frustoconical widened portion of an extension of the inner conductor of the coaxial feeder line, which widened portion constitutes the detonator head in the tip of the projectile and coincides, as regards position and direction, with the longitudinal axis of the projectile at the feed point of the antenna, and the wave trap which is also designed to be rotationally symmetrical to the longitudinal axis of the projectile.
