On polynomial approximation of current along thin asymmetrical cylindrical dipoles

Abstract

Isolated asymmetrical cylindrical dipoles and two such parallel nonstaggered identical dipoles are analyzed using a polynomial approximation for current. If the lengths of the two dipole parts do not exceed <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0.5\lambda</tex> , numerical results indicate that the simplest second-order polynomial approximation suffices for most purposes. Only if very accurate current distribution is desired, the third-order polynomial distribution need be used.
