Antenna Concepts at 60 GHz, 77 GHz, and 100+ GHz forCommunicationsandRadar

Prof. Dr. Martin Schneider, RF & Microwave Engineering Laboratory,UniversityofBremen, Germany


The RF & Microwave Engineering Group of the University of Bremen is working in the field of RF, microwave, and millimeter wave frontends and antennas. Simulation, prototyping and characterization are done in our labs. Wafer prober stations and an anechoic chamber are used for measurements up to 170 GHz.
After an overview of our laboratory and its measurement facilities, I’ll present some results of our recent work. First I’ll talk about our work on 60 GHz planar patch arrays for high data rate communications realized on a new thermoplastic material from NOF/Marubeni (Japan). We are also using this low loss substrate for antennas at 77 GHz (car radar applications) and even beyond 100 GHz. Our results at these frequencies will be shown.
Because fabrication tolerances are very critical at millimeter wave frequencies, we are also investigating antenna in package (AiP) concepts that allow much higher precision in fabrication. Here, we are involved in a joint project called RoCC (Radar on Chip for Cars), funded by the German government, where German car makers (BMW and Daimler), suppliers (Robert Bosch, Continental, Infineon) and German universities are cooperating in the investigation of future car radar concepts. In the RoCC project, we are realizing AiP prototypes based on the eWLB (embedded Wafer Level Ball Grid Array) concept from Infineon, which allows for wafer‐level precision for millimeter wave circuitry at reasonable costs. I’ll talk about the main ideas of this concept and I’ll present our first results based on this approach.

Prof. Dr. Martin Schneider
Dr. Schneider received a Diploma and a Doctorate degree in Electrical Engineering and Information Technology from the University of Hanover, Germany, in 1992 and 1997, respectively.
From 1997 to 1999, he was with Bosch Telecom GmbH in Backnang, Germany, where he developed passive microwave components for pointto‐point and point‐to‐multipoint radio link systems.
In November 1999, he joined the Corporate Research and Advanced Development division of Robert Bosch GmbH in Hildesheim, Germany. As a project and section manager of the “Wireless Systems” group he focused on research and development of phased array and smart antenna concepts for automotive radar sensors at 24 and 77 GHz.
From 2005 to 2006, Mr. Schneider was with the business unit “Automotive Electronics-Driver Assistance” of Robert Bosch GmbH in Leonberg, Germany. As a section manager he was responsible for the “RF Electronics and Mechanical Car Integration” group for automotive radar sensors.
Since March 2006, he has been a full professor and head of the “RF & Microwave Engineering” department at the University of Bremen, Germany. His current research topics are RF front end circuits, millimeter wave circuits, and antenna systems at millimeter wave frequencies up to 170 GHz.
Dr. Schneider is a member of IEEE, VDE, and VDI.
