ACE Activity 2.3 structuring of wideband & multiband antenna research

Developments in wireless communications and sensing require increasingly wider frequency bands and that multiple junctions can be provided by a single antenna system. This paper presents an overview of the current work in ACE Activity 2.3, which coordinates and structures European research on wideband and multiband antennas. The activity comprises three work packages: WP 2.3-1 on wideband & multiband radiators, WP 2.3-2 on reflector surface models, and WP 2.3-3 on antennas for subsurface radars. The paper discusses main areas of joint research and development, presents main results achieved, and relates the work to that of other ACE Activities. Main future challenges will be to maintain at least some of the current activities, when the funded period of ACE finishes by the end of 2007, and extend the cooperation to more partners in the ACE Community.
