Abstract :
The Norton equivalent circuit of a receiving antenna consists of a current generator feeding two admittances in parallel, Ya and YL. Admittance YL represents the load, and the power dissipated in YL, evaluated by "circuit" methods, correctly represents the actual electromagnetic power delivered to the load. The symbol Ya represents the input admittance of the antenna radiating in its transmitting mode. Whether the power dissipated in Ya, again evaluated by circuit methods, is equal to the power scattered by the antenna has been a matter of controversy for quite a few years. The present note seeks to review that recurring problem.
