Phased arrays and reflectarrays
|
|
The course, which will be given by speakers belonging to key players in
this field both in the industrial and academic environment, will be
articulated over five days. The first three days of lectures will be
concerned about phased array, and the next two about reflectarrays. The
lectures about phased arrays will offer to the attendees both the
basics of the array analysis and design and a wide panoramic of both
systems under production and new generation of systems presented
directly by some of the largest companies in Europe. Several fields of
applications will be reviewed during the course, ranging from advanced
arrays for space applications to complex radar systems for military and
civil applications. The most advanced EM modelling techniques for such
complex problems will also be presented highlighting the connection to
the real problems and real systems that antenna engineers have to face
in their "everyday" working environment. The last two days will be
concerned with basic theory, applications and new trends in
reflectarray antennas. Basic theory for the analysis and design of
reflectarrays will be presented, with special emphasis on the method of
moments applied to the analysis of periodic and truncated periodic
structures in a multilayer environment. Two classical implementation of
phase-shifters will be considered: (1) adjustment of dimensions in
rectangular patches in single and stacked configurations, and (2)
microstrip stubs of different length aperture-coupled to the radiating
patches. The control of phase-shift at each element allows a simple
realization of contoured beam and multi-beam antennas easier to
manufacture than shaped reflectors. Lectures will be presented for the
treatment of beam reconfigurability implemented by adding switches or
varactors at element or subarray level, but with lower degree of
complexity than in phased arrays. Lecturers will also concerned with
synthesis techniques for contoured beam and multi-beam reflectarrays
and active reflectarrays. Theoretical and experimental results will be
presented for some representative applications, as satellite DBS
antennas and LMDS base station antennas.
