Abstract :
A sum rule for horizontal thin-wire dipole antennas backed by a perfectly conducting ground plane is presented. It is an integral identity for the extinction cross section of a conducting dipole multiplied by a weight function under a linearly polarized plane wave illumination. The weighted integral is found to be proportional to the static polarizability of the original and image dipoles in free space.
