We are pleased to offer a free online short course entitled “Introduction to Antennas”, by Dr. David Prinsloo from The Netherlands Institute of Radio Astronomy (ASTRON). The course will take place on three days (February 15, 17, 19, 2021), between 13h-16h CET. It will be streamed over Webex.


Sign Up for the “Introduction to Antennas” Course is now closed! All those who signed up will receive an email with the course information soon.


The course will cover the following topics:

I. Fundamental Antenna Parameters

  • Far-field regions and radiation patterns
  • Radiation intensity, directivity, gain and effective area
  • Polarization
  • Operating principle of antennas
  • Equivalent networks
  • Reciprocity
  • Friis Transmission Equation, EIRP, and antenna factor

II. Basic Antenna Types

  • Antennas over a ground plane
  • Wire antennas
  • Microstrip antennas
  • Aperture antennas
  • Reflector antennas

III. Antenna Arrays

  • Linear array
  • Planar array
  • Regular and irregular arrays
  • Embedded array elements

Dr. David 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. In addition to the design and electromagnetic modelling of antennas for various radio telescope projects, he regularly gives lectures on antennas to students with various backgrounds. He also holds a guest researcher position with Eindhoven University of Technology where he acts as supervisor to post-graduate students within the Centre for Wireless Technology at the department of Electrical Engineering.


The STELLAR project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 952439. It is coordinated by the Institute of Astronomy, Bulgarian Academy of Sciences.
