Supervision

François Sarrazin: Junior Professor Chair at Université de Rennes
Philippe Besnier: Research Director at CNRS
Keywords:Antenna characterization, Miniature antenna, Reverberation chamber
Objectives and Work Plan:Reverberation chambers (RCs) have become a reliable alternative to anechoic chambers to perform antenna radiation pattern [2] and efficiency measurement [3]. The objective of this PhD is to develop a contactless antenna measurement method suitable for low efficiency and buried antennas, based on our recent proofofconcept [4].

The work plan is the following:

Develop new analytical models of antenna scattering and absorbing properties within reverberation chambers.
Develop the measurement protocol and test bench to retrieve antenna parameters from noninvasive scattering parameters measurements.
Validate the approach first in a freespace scenario and then for antennas buried in a complex medium.
Evaluate the measurement uncertainties regarding the antenna and RC properties.
