A German BMWI/DLR project: The goal of SANTANA III is the development of new technologies for planar electronically steerable antennas for mobile applications, including satellite communications on ships, cars and airplanes. The project covers the research and development of innovative system architectures and new antenna concepts. A special focus of SANTANA is the creation of a flat electronically steerable antenna using digital beam forming at Ka band. Now in the third project phase, a new system architecture has been developed that can handle several thousand radiating elements in parallel. This innovative concept will be presented at the end of this project phase.
