Abstract :
A numerical technique is applied to find the current distribution on 4-arm Archimedian spiral antennas printed on a dielectric substrate. The integral equation for the current distribution is formulated, which is solved by using the parametric B-spline finite element method. Numerical results of the current distribution for different dielectric permittivities are presented, showing that the current distribution on the 4-arm Archimedian printed spiral antenna has a standing-wave nature
