Germany Printed Radar Tender

Parking a car with the help of radar sensors already is commonplace. Many other applications of radar technology are obvious such as precise distance and environment sensors for robots and machines in the industrial automation sector or high-performance transmitters and receivers in telecommunications. Concrete application scenarios however are highly individual the number of pieces is small and manufacturing costs are very high. This is the point of departure of the new DiFeMiS Research Laboratory at Karlsruhe Institute of Technology KIT. It is to develop print technologies for individual small and inexpensive high-frequency systems up to the terahertz range THz. The Laboratory is funded by the Federal Ministry of Education and Research BMBF with about EUR 3.37 million.When thinking of electronics we mostly think of components on a green circuit board. But this carrier of electric components is suited for circuits working at frequencies far below 100 GHz only. At higher frequencies boards are mainly produced by lithographic processes optimized for mass production. For medium batches of up to 10000 products typically produced by small and medium-sized enterprises SME fabrication of an exposure mask for lithography is too expensive. Latest additive processes and precision printing technology might close this gap between individual and mass production.The core component of the planned Research Laboratory is a configurable micrometer-precise printing platform for future highly flexible and inexpensive packaging says Professor Thomas Zwick who heads KITs Institute of Radio Frequency Engineering and Electronics. Packaging or assembly and connection technology refers to all microchip-supporting components on a circuit board from the conducting wire to the antenna. Packaging largely depends on the application as far as the size and orientation of antennas are concerned for instance. Hence mass-produced off-the-shelf solutions are hardly suited. At very high frequencies up to the terahertz range radar technology is suited for many applications as the high frequency enables increased measurement accuracy higher data transmission rates and further miniaturization.The Research Laboratory at KIT combines systems for additive and mask-less deposition and structuring methods in a flexible printing platform. Special measurement systems can be applied to determine the frequency behavior of components and systems at more than 500 GHz. To print electric circuits several methods are available. Here materials with various electric properties are applied as inks. These methods are two-dimensional such ink-jet and aerosol-jet printing or three-dimensional such as laser lithography. For circuits above a frequency of 100 GHz resolution has to be increased and complementary properties have to be combined. The big challenge lies in the exact positioning of components. For this purpose printing processes are to be adjusted with micrometer precision such that optimum collaboration of components from different printers is ensured and circuits are kept as small as possible.SME might use digital manufacturing processes for inexpensive assembly and connection techniques at frequencies above 100 GHz in order to develop a large number of sensor applications for Industry 4.0 and robotics. Here many measurement tasks have to be carried out from simple distance measurements to complex imaging. Thanks to their good resolution high accuracy small size and high robustness high-frequency sensors are particularly suited for this purpose. Moreover emitters and receivers based on high-frequency systems might be applied in telecommunications. Digital manufacturing might enable customized integrated and inexpensive production.At KITs Research Laboratory three research groups of Professors Thomas Zwick Ulrich Lemmer and Christian Koos from the Institute of Radio Frequency Engineering and Electronics Light Technology Institute and Institute of Photonics and Quantum Electronics are involved in DiFeMiS German acronym of digital manufacture of THz microelectronics systems. The newly established chair of Ahmet Cagri Ulusoy at the Institute of Radio Frequency Engineering and Electronics is to join the project in the near future. The Laboratory will be funded by the Federal Ministry of Education and Research BMBF under the program Microelectronics Research Laboratories in Germany with EUR 3.37 million for a period of three years. Investments in most modern devices and facilities are to enable research on top international level. The twelve laboratories to be established under this program will open up new areas of research for future microelectronics and be used for training young scientists.At todays kick-off event Thomas Rachel Parliamentary State Secretary with the BMBF underscored the importance of the research laboratories as an investment in the future. We want to continue to live a self-determined life in a rapidly changing world. For this Germany and Europe need to have a strong technological basis. The Microelectronics Research Laboratories in Germany provide an essential contribution. At these laboratories electronics for the next decades will be developed to maturity and new ideas and know-how will be transferred very quickly to everyday use.Being The Research University in the Helmholtz Association KIT creates and imparts knowledge for the society and the environment. It is the objective to make significant contributions to the global challenges in the fields of energy mobility and information. For this about 9300 employees cooperate in a broad range of disciplines in natural sciences engineering sciences economics and the humanities and social sciences. KIT prepares its 25100 students for responsible tasks in society industry and science by offering research-based study programs.
