Abstract
One approach to making a transient radiating and/or receiving antenna, involves a timed array which allows one to steer the beam without physically rotating the antenna. An array of interconnected elements (unit cells) can be used to give a very broadband characteristic. Various designs of such unit cells are reviewed and discussed for single and dual polarization. The low-frequency part of the pulse spectrum is governed by the electric and magnetic dipole moments dipole moments of the array and additional conductors (impedance loaded) connected to the array.
