The EU Framework Programmes (FPs) foster the collaboration and the research structuring across Europe. In FP6, the Antenna Centre of Excellence (ACE) is a Network of Excellence project created to improve the efficiency of antenna research in Europe. Starting 1 January 2004, it has a duration of 4 years and 51 participants from 17 European countries. 323 researchers and 130 PhD students are involved. The ACE activities are focused on mm-wave and integrated antennas, wideband and multiband antennas, small and smart antennas, active and passive planar and conformal arrays, software, testing, education and dissemination in the antenna area. After ACE, EurAAP, the European Association for Antennas and Propagation will continue the coordination work.
