A priori estimates on the partial realized gain of UWB-antennas

Sohl, Christian LU and Gustafsson, Mats LU (2008) XXIXth URSI General Assembly 2008 p.1-4
Abstract
A summation rule valid for a large class of linear and reciprocal antennas is presented in terms of the electric and

magnetic polarizability dyadics. The identity is based on the holomorphic properties of the forward scattering dyadic

and includes arbitrary shaped antennas modeled by linear and time-translational invariant constitutive relations. In

particular, a priori estimates on the partial realized gain are introduced, and lower bounds on the onset frequency

is derived for two important archetypes of UWB-antennas. The theoretical findings are illustrated by the equiangular

planar spiral antenna, and comparison with numerical simulations show great potential for future use in antenna theory.
