dc.description.abstract | A spherical discrete lens antenna based on the back-toback
combination of two choked-horn antennae arrays
interconnected through smooth waveguides sections
implementing the spherical phasing law, has been
designed, simulated and fabricated.
The spherical phasing law of the lens converts the
incoming spherical phase front, from a small feeder
placed at the focal plane, into a plane phase front.
Depending on the feeder position at the focal plane (the
perpendicular plane to the len's axis containing the focal
point) the beam is pointed in different directions. The
minimum angular distance between two beams is
directly related to the minimum distance between two
adjacent positions of low directive and, therefore, small
feeders.
The selected implementation offers several advantages
compared to an actually curved lens, such as the
simplification of the fabrication, the constant length of
the phasing waveguides and the dispersion of the backscattered
power, reducing significantly the coupling
between feeders. | en |
