History Uncovered in Electromagnetics and Antennas
A fascination for me is how in the antenna field, theory often anticipates an application. In this talk I will give several examples and detail my recent research interest in antenna history. My journey here commences with the uneducated Michael Faraday who through his genius, his own hard work, and desire to improve himself became one of the leading scientists of his day. One of his discoveries of importance for electromagnetics and radiation was induction. His and others. search on induction will be outlined. Another pioneer in radio communication described is Karl Ferdinand Braun. He received a PhD from the University of Berlin in 1872. Afterwards he published a paper on rectification in metal sulfide crystals and invented the cathode ray tube. He went on to participate in the formation of Telefunken, invented the first phased array antenna, and won the Nobel prize jointly with Marconi in 1909. I will expand more on phased array topics including mutual coupling, and arrays of closely spaced elements, which were first proposed by John Kraus in 1940. Twenty-five years later, Harold Wheeler described a current sheet antenna, which, as it turns out can be created by a Kraus closely spaced array. Finally, in this overview of early antennas, I will outline the history of the folded dipole and give some of its properties. Within the history and application of the folded dipole is an Australian story.

Prof Trevor S. Bird
Biography:
Trevor S. Bird is Principal of Antengenuity a specialised consultancy firm, and a Distinguished Visiting Professor at the University of Technology, Sydney (UTS). He graduated with a PhD from the University of Melbourne in 1977. Afterwards he worked in the UK, lectured at James Cook University of North Queensland, and was a research scientist at CSIRO. He was Chief Scientist of the CSIRO ICT Centre from 2004 to 2011 and became a CSIRO Fellow in 2007.
He has published over 400 papers, 2 books, 12 book chapters, and holds 12 patents. He is Fellow of the Australian Academy of Technological Sciences and Engineering, Life Fellow of IEEE, IET Fellow, Fellow of the Royal Society of NSW, and an Honorary Fellow of the Institution of Engineers.
Prof. Bird has received numerous awards including three CSIRO Medals for research achievement, the IEEE Third Millennium Medal, and a Centenary Medal for service to Australian society in telecommunications. He was a Distinguished Lecturer for the IEEE Antennas & Propagation Society from 1997 to 1999. He was Editor-in-Chief of the IEEE Transactions on Antennas & Propagation from 2004 to 2010, and in 2013 he was President of the IEEE Antennas & Propagation Society.
