GPS ANTENNA DEVICE FOR ARTILLERY PROJECTILES

摘要

PURPOSE: A satellite navigation antenna device for a shell is provided to secure the wide beam width to a high angle of the shell, thereby easily receiving a plurality of satellite navigation signal. CONSTITUTION: A ceramic patch antenna is comprised of a ceramic dielectric substance (132), and a radiation element (131). The radiation element is arranged in an upper side of the ceramic dielectric substance. A metal earth plate (140) is arranged in the lower side of the ceramic dielectric substance. A coaxial line electrically connects the radiation element with the electronic unit of the shell. The electronic unit has a communication function.
