The Limiting Quality Factor of Electrically Small Antennas Inscribed into a Cylinder and an Ellipsoid

Abstract

The estimations of the bound of the quality factor for electrically small antennas inscribed in a cylinder and the triaxial ellipsoid are obtained. For antennas whose shape is far from spherical, the above estimation allows to refine the Chu-McLean limit.
