Compliance of antenna systems with regulations outlined by standard development organizations and governmental institutes is of utmost importance to ensure reliable communication and to mitigate health risks. Accurately characterizing antenna systems is therefore extremely relevant and important.

A.J. (Teun) van den Biggelaar received his MSc degree in Electrical Engineering (EE) with distinction from the Eindhoven University of Technology (TU/e), the Netherlands, in 2016. His MSc thesis was selected as the best MSc thesis of the department of EE in the year 2016. Teun continued his academic career as a Doctoral Candidate in the Electromagnetics (EM) group of the department of EE, TU/e, and received his PhD degree with distinction in 2020. During these four years, he worked on a project supported by NXP Semiconductors in Nijmegen, the Netherlands. Additionally, he had been a guest researcher at the National Institute of Standards and Technology (NIST) in Boulder, USA, for a period of six months. Currently, he is a guest researcher at the TU/e and focuses on over-the-air measurement systems and techniques for millimeter-wave 5G systems.

Teun van den Biggelaar is a guest researcher at the Electromagnetics (EM) group, led by professor Bart Smolders. Currently, he is working on over-the-air measurement systems and techniques for millimeter-wave 5G systems. Examples of these systems include anechoic chambers to measure the gain and radiation pattern of an antenna, reverberation chambers to determine an antenna's efficiency, and open cavity resonators to determine the electromagnetic properties of materials.
