Antenna pattern reconfigurability is considered as a major interest for satellite telecommunications. Satellite operators are willing to optimise the use of their spacecraft fleet overall capacity. This requires the ability of performing traffic reassignment either just before launch or preferably in flight. Beside single shaped beam covering different continental areas, multiple pencil beam or linguistic beams are today required. Reconfigurable antennas are expected to offer advantages in one/ several of the following areas:

	Capability to optimise the coverage and performances when operating from several orbital slots and providing fast back-up with existing spacecrafts,
	Frequency and polarisation (both linear or circular) flexibility,
	In orbit antenna pattern shaping capability to cope with rapid market changes and increasing satellite lifetime,
	Power to beam allocation flexibility,
	Ability to re-point and zoom the beam on the complete visible earth or on a continental area,
	More generic antenna design with positive impact on schedule.

Beside single or multiple beams reconfigurability, it is also of major interest to develop antennas generating several overlapped beams from a single aperture. Discussions on most appropriate configurations for transmit, receive or transmit/receive are awaited.

Considering the large active antennas flight heritage, synergy with architectures and technologies implemented in other applications such as Earth Observation and possibly science is also an important aspect to be explored.

Papers are expected to focus on antenna overall architecture, technologies applicable to all the sub-systems as well as design and tests methodologies. The following classes of topics are suggested:

1.	Single/Multiple reconfigurable beam space antennas
2.	Multiple beam antennas using a single aperture
3.	Focused and de-focused reflector based antennas
4.	Direct Radiating Arrays based antennas including sparse and thinned arrays
5.	Reflectarrays and lenses based Antennas
6.	Design and technologies for antenna sub-systems and active/passive equipments
7.	New enabling technologies, materials and processes for antenna RF, mechanical and thermal design and optimisation
8.	Terminal antennas for aeronautic, car, trains,..
9.	Modelling methodologies and tools for multiple beams antennas
10.	Test techniques applicable to multiple beams antennas
11.	Synergy with other applications
12.	Others
