Physical bounds and summation rules in antenna theory

Gustafsson, Mats LU and Sohl, Christian LU (2008) XXIXth URSI General Assembly 2008 p.1-4
Abstract
Although the concept of physical bounds for electrically small antennas was first introduced more than half a century

ago by Wheeler and Chu it continuous to receive attention and still there is only a partial knowledge of these bounds.

Most of the research effort in this field are based on the ideas of a stored energy in the different partial waves as

introduced by Chu and, hence, suffers from the same shortcomings. The objective of this paper is to present three

alternative approaches to derive physical bounds on antennas that are solely based on the assumptions of linearity, timetranslational

invariance, causality, and reciprocity. These assumptions are utilized in three different scattering... (More)
