Abstract:

Series-fed arrays occupy a distinctive place in antenna engineering, providing a simple, elegant, and efficient solution for a wide range of high‑gain applications, from classical high-power slotted waveguide antennas to modern millimeter‑wave automotive radar systems. Despite being a well‑established technique, series feeding has not lost its relevance, and there remains significant potential for continued innovation.

This presentation revisits the fundamental concepts that underpin series-fed arrays, starting with classical realizations and landmark contributions that have shaped the field. A tutorial introduction to series-fed array design is provided, with particular emphasis on physical intuition and the key constraints that have guided their development over decades.

In the second part of the talk, the continuing potential for innovation in this mature area is illustrated through several new series-fed configurations. These include linear, circular, and spiral architectures, as well as multi-mode, multi-port arrangements offering attractive performance for applications such as polarimetry and tracking.

Overall, this plenary aims to show how simplicity and classical elegance continue to provide fertile ground for innovation, enabling enhanced performance and offering valuable insight for addressing future challenges in antenna technology.

Prof. Christophe Fumeaux of The University of Queensland

Topic:

Series-Fed Arrays: Classical Elegance and New Insights

Biography:

Christophe Fumeaux received his Ph.D. degree from ETH Zurich, Switzerland, in 1997. From 1998 to 2008, he held various positions at the University of Central Florida, the Swiss Federal Office of Metrology, and ETH Zurich. From 2008 to 2023, he was a Professor with The University of Adelaide. In 2023, he joined the School of Electrical Engineering and Computer Science at The University of Queensland, as Chair Professor in Optical and Microwave Engineering. His main research interests concern applied electromagnetics, antenna engineering, and the application of RF design principles across the electromagnetic spectrum.

Prof. Fumeaux was the recipient of the ETH Medal for his doctoral dissertation. He was the recipient of the 2018 Edward E. Altshuler Prize, the 2014 IEEE Sensors Journal and the 2004 ACES Journal best paper awards. He was the recipient of the University of Adelaide 2018 Stephen Cole the Elder Award for Excellence in PhD Supervision. From 2017 to early 2023, he served as the Editor-in-Chief for the IEEE Antennas and Wireless Propagation Letters. He was 2025 President of the IEEE Antennas and Propagation Society and he is currently serving as IEEE AP-S Vice-President of Publications. He is a Fellow of the IEEE.
