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. Speaker(s): Prof Trevor S.
