Abstract
A spiral antenna device includes one or more conductive spiral arms that are formed on a dielectric substrate attached to a wall of a cylindrical cavity. One or more coils are formed on the wall of the cylindrical cavity and are coupled to the one or more conductive spiral arms. Starting points of the one or more conductive spiral arms are in a center region of the dielectric substrate and ending points of the one or more conductive spiral arms are electrically coupled to first ends of the one or more coils.
