The reflectometer is verified with a circuit breakout including an integrated dummy sensor. The reflectometer is able to measure the phase of the reflection coefficient from 117 to 134 GHz with a resolution of 0.1° and a standard deviation of 0.082°. The integrated sensor with the reflectometer circuit have been fabricated in a 190-GHz fT SiGe:C BiCMOS technology. It spans an area of 1.4 mm 2 and consumes 75 mA from a 3.3-V supply. The circuit has been assembled on a printed circuit board for characterization by immersion into test liquids. The sensor is controlled by a controller board and a personal computer enabling a measurement time of up to 1 ms per frequency point. Functionality of the sensor is demonstrated from 118 to 133 GHz with immersion of the sensor into different binary methanol-ethanol mixtures, showing good correlation between theory and measurement.

Measurements of the antenna including the flip chip interconnect are presented that have been achieved by replacing the IC with a dummy chip that only contains a through-line. Afterwards, radiation pattern measurements are shown that were recorded using the radar sensor as transmitter. Finally, details of the fully integrated radar sensor are given, together with results of the first Doppler measurements."}],"publication":"7th EUROPEAN CONFERENCE ON ANTENNAS AND PROPAGATION","type":"conference","title":"Flip-Chip Package with Integrated Antenna on a Polyimide Substrate for a 122-GHz Bistatic Radar IC","date_created":"2021-09-14T09:22:26Z","author":[{"full_name":"Beer, Stefan","last_name":"Beer","first_name":"Stefan"},{"last_name":"Girma","full_name":"Girma, Mekdes Gebresilassie","first_name":"Mekdes Gebresilassie"},{"first_name":"Yaoming","full_name":"Sun, Yaoming","last_name":"Sun"},{"full_name":"Winkler, Wolfgang","last_name":"Winkler","first_name":"Wolfgang"},{"last_name":"Debski","full_name":"Debski, Wojciech","first_name":"Wojciech"},{"last_name":"Paaso","full_name":"Paaso, Jaska","first_name":"Jaska"},{"first_name":"Gerhard","full_name":"Kunkel, Gerhard","last_name":"Kunkel"},{"id":"37144","full_name":"Scheytt, Christoph","last_name":"Scheytt","first_name":"Christoph"},{"first_name":"Jürgen","last_name":"Hasch","full_name":"Hasch, Jürgen"},{"first_name":"Thomas","full_name":"Zwick, Thomas","last_name":"Zwick"}],"date_updated":"2022-01-18T10:23:24Z","citation":{"short":"S.

The calibration relies on direction of arrival measurements of the individual arrays. The proposed calibration algorithm is derived from a maximum-likelihood approach employing circular statistics. Since a sensor node consists of a microphone array with known intra-array geometry, we are able to obtain an absolute geometry estimate, including angles and distances. Simulation results demonstrate the effectiveness of the approach.","lang":"eng"}],"language":[{"iso":"eng"}],"keyword":["Geometry calibration","microphone arrays","position self-calibration"],"related_material":{"link":[{"description":"Presentation","relation":"supplementary_material","url":"https://groups.uni-paderborn.de/nt/pubs/2013/JaScHa13_Presentation.pdf"}]},"publication_identifier":{"issn":["1520-6149"]},"citation":{"chicago":"Jacob, Florian, Joerg Schmalenstroeer, and Reinhold Haeb-Umbach. “DoA-Based Microphone Array Position Self-Calibration Using Circular Statistic.” In <i>38th International Conference on Acoustics, Speech, and Signal Processing (ICASSP 2013)</i>, 116–20, 2013. <a href=\"https://doi.org/10.1109/ICASSP.2013.6637620\">https://doi.org/10.1109/ICASSP.2013.6637620</a>.","ieee":"F.
