The first activity of the STELLAR project took place in mid-February! The Introduction to Antennas course, originally planned to be held at ASTRON (in Dwingeloo, The Netherlands) for up to six people (faculty, researchers, and students) from the Institute of Astronomy (BAS) and the Technical University of Sofia, was transformed into an online course due to the COVID-19 pandemic. The course was attended by 57 participants from 13 research institutions!
The short course was held over Zoom, as three separate three-hour-long lectures. It was led by Dr. David Prinsloo of ASTRON – an expert in the design of antennas and antenna arrays for radio astronomy. Dr. Prinsloo is a researcher with the Smart Front-ends Group at the Innovations and Systems department of The Netherlands Institute for Radio Astronomy. His primary research interest is on antenna designs for both phased array and reflector-based radio telescopes.
The course participants learned the ins and outs of fundamental antenna parameters, basic antenna types, as well as antenna arrays. As the final module of the course, the students participated in the design of a realistic antenna array.
