A fully polarimetric broadband antenna for emitting and receiving non- dissive EMP signals has dipole elements orthogonally mounted on a ground plane which tilts the elements relative to the direction of wave propagation. The ground plane can be shaped into either a pyramid or cone, and the elements may be truncated cones or substantially discus-shaped. A single-pole-single-throw reed relay is mounted between dipole elements which are independently driven to provide horizontal and vertical polarizations. The antenna provides a response and pattern suitable for transmitting short EMP signals useful in radar and communications applications.
