The proposed design methodology leads to a highly sensitive biosensor structure, which is fabricated on Rogers 3003 material. It is shown that a sufficiently high sensitivity is achieved to monitor the cultivation stadium of a yeast culture based on detection of permittivity changes. The obtained measurement results show good agreement with the performed full 3D EM simulations. According to these results the presented biosensor is capable of characterizing the stage of yeast cultivation label-free and contactless.}}, author = {{Wessel, Jan and Schmalz, Klaus and Cahill, Brian and Gastrock, Gunter and Scheytt, Christoph}}, booktitle = {{Microwave Conference (EuMC), 2012 42nd European}}, title = {{{Microwave Biosensor for Characterization of Compartments in Teflon Cappilaries}}}, doi = {{10.23919/EuMC.2012.6459231 }}, year = {{2012}}, } @inproceedings{24404, abstract = {{Precise position is necessary for a robot to reliably localize itself and navigate in the environment.

The software architecture has been designed to take into consideration the need for a flexible and scalable system that can interoperate with many similar systems and support different types of image sources, image processing, and outputs. With the architecture, future enhancements or replacements can be implemented as plug-ins, which can be easily integrated into the system.

Developing ultrawideband architectures including multiple-input-multiple-output (MIMO) antenna systems at mm-W offer many advantages including jointly optimized analogue and digital signal processing at carrier frequency and baseband. This allows for flexible antenna designs and reduced losses, as many passive structures can be avoided at both sides of the link. Besides, based on flexible polarimetric approaches, the polarimetric propagation of electromagnetic waves can be exploited. In this paper we present a 60 GHz polarimetric MIMO system architecture, which includes analogue miniaturized frontends designed and manufactured by multi-layer packaging technologies. Such architecture permitted the design of compact MIMO radar and multi-dimensional channel sounding. The MIMO approach allows not only polarimetric filtering and fully polarimetric/directional signal processing to increase the signal-to-clutter-plus-noise ratio of mm-W radar systems, but also the full characterization of wireless channels including multipath with orthogonal polarizations.}}, author = {{Garcia-Ariza, Alexis-Paolo and Müller, Robert and Stephan, Ralf and Wollenschläger, Frank and Schulz, Alexander and Elkhouly, Mohamed and Scheytt, Christoph and Trautwein, Uwe and Müller, Jens and Thomae, Reiner and Hein, Matthias}}, booktitle = {{EuCAP2012 (European Conference on Antennas and Propagation)}}, pages = {{2578--2582}}, title = {{{60 GHz Polarimetric MIMO Sensing: architectures and technology}}}, doi = {{10.1109/EuCAP.2012.6206544}}, year = {{2012}}, } @inproceedings{24416, abstract = {{This paper describes the design of D-band phased-array circuits in 0.25 μm technology.

Regarding the post process in this work the cooling down phase is investigated as well.
