| 1. An antenna, comprising
an at least partly conically shaped body of dielectric material, having a series of cross-sections of truncated elliptical
shape, wherein each cross-section of truncated elliptical shape is truncated substantially through a first focus elliptical
shape along a truncation line that extends substantially perpendicularly to a main axis of the elliptical shape, a second
focus of the elliptical shape lying within the body; and
an elongated wave carrying structure extending substantially along a focal line through the first focus of the elliptical
shape in successive cross-sections of the series of cross-sections of truncated elliptical shape.
