Bachelor Thesis: Investigation and Mitigation of Common-Mode Emissions in RFID Systems (m/f/d)

Bachelor Thesis in Collaboration with NXP Austria

We are looking for a Bachelor’s student currently enrolled at an Austrian university/FH who would like to conduct their Bachelor thesis in collaboration with NXP Austria. The thesis topic will be defined in alignment with NXP and the respective educational institution. The thesis requires appropriate academic approval and supervision by the university/FH and will be carried out in accordance with the applicable university requirements.

Background: Common-mode currents can contribute significantly to unwanted electromagnetic emissions in electronic systems. Electrical asymmetries and interactions between different system components can convert differential signals into common-mode currents, potentially affecting EMC performance.

Research Topic: The objective of this thesis is to investigate common-mode current mechanisms in 13.56 MHz RFID systems, understand relevant coupling and radiation effects, and evaluate suitable mitigation approaches.

• Study common-mode and differential-mode current mechanisms
• Investigate potential radiation and coupling paths through measurements and analysis
• Study the influence of mechanical and electrical design parameters
• Evaluate mitigation approaches such as common-mode chokes, ferrites, shielding and grounding concepts
• Validate selected improvement measures experimentally and document the results

Your Profile:

• Ongoing enrollment in Bachelor studies of electrical engineering, biomedical engineering, information and computer engineering or similar
• Basic knowledge of RF electronics or EMC
• Interest in measurement techniques
• Willingness to perform hands-on laboratory work
• Solid English language skills

For the successful completion of the Bachelor Thesis you will receive a remuneration of a one-time payment of EUR 2.300, - gross. Depending on the performance and end-result, an add-on payment is possible.
