Abstract
A munitions employing explosively formed penetrator warhead includes a microstrip antennae pattern on its concave face and is configured such that its presence does not impede or deleteriously affect the ability of the EFP to form into a molten armor-piercing projectile following detonation. The concave surface of the warhead serves as the conductive ground plane for the microstrip antennae and a dielectric layer having the microstrip antennae pattern formed on a first surface thereof is bonded to the warhead. A feedthrough which passes through an aperture near the edge of the warhead allows the antennae to be coupled to the transmit/receive electronics used along with the antennae to detonate the munitions upon its reaching a predetermined standoff distance from the armor surfaces of the target to be destroyed.
