| 摘要 |
A proximity sensing device comprising an antenna unit having a substantially longitudinal antenna extending therefrom, the antenna being encased along a substantial part of its length between an interior encasement portion and an exterior encasement portion, said encasement portions being configured so as to substantially immobilise the antenna, and the exterior encasement portion being adapted to permit the transmission of electro-magnetic radiation therethrough. The proximity sensing device is particularly suitable for use within the fuze of a projectile. The proximity sensing device advantageously has a dipole antenna.
