Roboter-Nahfeldmessung unter Verwendung der Einzelsonden-OTF-Technik

Kontakt: Dr. Cheng Yang (Oberingenieur)

Die Nahfeldmessung (NFS) spielt eine entscheidende Rolle bei der Bewertung der Strahlung und Emission von elektromagnetischen (EM) Feldern, die von Mikrowellengeräten und -komponenten ausgehen. In den letzten Jahrzehnten wurden erhebliche Fortschritte bei der Verbesserung der Scankapazitäten erzielt, einschließlich des Einsatzes von Robotik, Hochgeschwindigkeitsgerätekommunikation und Ausrüstung mit hoher Abtastrate. Trotz dieser Fortschritte sind die Zeit- und Kostenbeschränkungen für Messungen immer noch durch Anforderungen an groß angelegte, hochauflösende Magnituden- und Phasenmessungen begrenzt, insbesondere in Bezug auf integrierte Schaltungen (IC) und Antennenanwendungen im Zusammenhang mit elektromagnetischer Verträglichkeit (EMV) Tests.

Dieses Projekt zielt darauf ab, die Zeit- und Kostenbelastungen herkömmlicher Nahfeldmessungen (NFS) um das Zehnfache zu reduzieren, ohne dabei die Genauigkeit zu beeinträchtigen. Dies wird durch den Einsatz einer innovativen Einzelsonden-On-the-Fly (OTF)-Datenakquisitions- und Verarbeitungstechnik erreicht. Als Nachweis wurde eine Spulenantennenbeispiel getestet, wie in (a) und (b) dargestellt. Die Technik wird auf kostengünstige Innen- und Außen-EMV-Tests bis zu GHz-Frequenzen ausgeweitet.
