Abstract :
Equations to calculate near-field radiation of an hemispherical spiral irradiator are presented. The optimal number of spiral irradiator coils for application in reflector antennas is determined. It is also established that circular polarization eliminates an additional cross-polarized component under signal re-reflection.
