DESCRIPTION: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 co
 mmences with the uneducated Michael Faraday who through his genius\, his o
 wn hard work\, and desire to improve himself became one of the leading sci
 entists of his day. One of his discoveries of importance for electromagnet
 ics and radiation was induction. His and others. search on induction will 
 be outlined. Another pioneer in radio communication described is Karl Ferd
 inand Braun. He received a PhD from the University of Berlin in 1872. Afte
 rwards 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 Nob
 el 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 o
 ut can be created by a Kraus closely spaced array. Finally\, in this overv
 iew of early antennas\, I will outline the history of the folded dipole an
 d give some of its properties. Within the history and application of the f
 olded dipole is an Australian story.\n\nSpeaker(s): Prof Trevor S. Bird\,
