Proceedings ArticleDOI
A review on six-port radar and its calibration techniques
TL;DR: This work gives an overview of Six-port networks and implementation technologies, and several state-of-the-art calibration techniques are discussed, which are necessary to achieve accurate displacement measurements.
Proceedings ArticleDOI
100 GHz reflectometer for sensitivity analysis of MEMS sensors comprising an intermediate frequency Six-port receiver
Sarah Linz,Florian Oesterle,Armin Talai,Stefan Lindner,Sebastian Mann,Francesco Barbon,Robert Weigel,Alexander Koelpin +7 more
TL;DR: This work presents a novel measurement setup for MEMS microphones, that allows an inline, contactless evaluation of the microphones' mechanical sensitivity at an early stage of the manufacturing process.
Proceedings ArticleDOI
Introducing new design guidelines for dualband CRLH structures formed by transmission lines and lumped components
TL;DR: In this paper, a new strategy for designing dualband composite right and left handed (CRLH) structures based on lumped elements is introduced, which can be easily scalable to arbitrary frequencies as the parasitic elements of the lumped components are considered.
Proceedings ArticleDOI
The enhanced six-port receiver: A new concept for simultaneous data reception and direction of arrival detection
TL;DR: In this paper, a method for simultaneous data reception and direction of arrival (DOA) detection in a six-port direct conversion receiver is presented. But it requires only one enhanced front-end.
Proceedings ArticleDOI
Ultra-low-power sensor node with wake-up-functionality for smart-sensor-applications
TL;DR: A complete mobile sensor node which has the ability to monitor temperature, atmospheric pressure, relative humidity, brightness and magnetic fields is presented and can also be localized within a previously calibrated area.
