Resumen
A novel leaky-wave antenna, based on a periodic set
of slots printed on a rectangular dielectric waveguide is conceived
in this work. The antenna presents the ability to independently
control the aperture illumination and the pointing direction,
by only modifying the photoetched printed-circuit layout. The
working mechanism is described using a leaky-mode dispersion
analysis, and cosine-tapered designs are performed at 50 GHz.
The radiation patterns are obtained using HFSS analysis to check
the reduction of sidelobes levels, and the capacity to tune the
pointing direction over a wide range of elevation angles.
