In the frame of the European Network of Excellence ACE, under the EU's 6th Framework Programme (FP6), the European Association on Antennas and Propagation (EurAAP) was created in 2005 and the following year the first European Conference on Antennas and Propagation (EuCAP) was organised in Nice, France, supported by the European Space Agency (ESA). In the spirit of the Millennium Conference on Antennas and Propagation AP2000, held in Davos, Switzerland, EuCAP2006 regrouped the former JINA and ICAP conferences, two ESA Workshops on Satellite Antennas and Propagation and the final Workshop of the EC COST Action 284 on Antennas. Since then, EuCAP has been organised yearly across Europe. As a key step in the EurAAP efforts to structure and coordinate Antenna and Propagation research in Europe, EuCAP has provided a forum for the European R&D communities in the Antennas and Propagation field, at both academic and industrial levels. With an average attendance around 1200 delegates, EuCAP has provided the ideal place for the exchange of scientific and technical information, and to foster collaboration and cooperation in the Antenna and Propagation domain, at both European and global levels. With this aim, EuCAP has been a regular keystone event on Antennas and Propagation, with a large participation of the world community. In addition to enabling the exchange of information and the access to the latest developments in the field through guest speakers and paper presentations, the conference features exhibitors demonstrating software, equipment, and technology. A wide variety of applications, ranging from mobile and satellite communications to medicine are addressed. Since the first editions, EuCAP has hosted AMTA activities through the organisation of special sessions and technical tours and has active relations with the EurAAP associated international organizations.
