Abstract :
A conformal Archimedian spiral antenna above a cylindrical groundplane is modelled using a curved segment moment method incorporating closed form Green´s functions to describe the cylinder for maximum computational efficiency. Asymptotic input impedances agree well with a planar geometry.
