TITLE: You Can Do That? Twenty Five Years of Fractal Antennas
  
Abstract: This year marks the 25th year of the creation and recognition of fractal antennas as a new and worthwhile class of antenna design. Despite this longevity, published summaries remain poor in accuracy and detail, although fractal antenna advantages are unrealized with other design approaches. This talk presents a variety of ways in which fractal antenna technology (including fractal resonators and fractal metamaterials) has been used to produce: smaller, multiband antennas without components; wideband invariant antennas with huge bandwidths; sparse array that are frequency invariant and low in sidelobes; lower profile antennas with better performance on metal; extremely low RCS radar targets; fractal metasurface wideband radiators; wideband invisibility cloaks; rapid convergence design algorithms; and so on. I will also debunk claims about electrically small antennas; 'ecumenical' antenna performance; and so on, which have prevented more rapid progress in fractal antenna acceptance in the United States. A live demonstration will also be shown.
 
Bio: Nathan Cohen is the CEO of Fractal Antenna Systems, Inc. of Waltham, MA. He is the founder of fractal antenna technology and holds over 2 dozen patents on them. Previously he was an academic radio astronomer and physicist who retired as a professor from Boston University in 2002. He holds a Ph.D. from Cornell University and conducted his thesis work at Haystack observatory on Very Long Baseline Interferometry (arrays) and gravitational lenses. He has authored over 80 papers and 3 books.

We want to hear from you! CFP 2013 IEEE International Symposium on Phased Array Systems & Technology



During recent decades, phased array systems have made major steps forward with the development of many major radar and communications systems. due to many recent advances, including MMIC, photonics, and digital beamforming, phased array systems and technology continue to progress rapidly. Current and future developments of ground-based, sea-based, airborne, and space-based phased array radar, communications, and other electronic systems will be discussed at this international symposium.

Phased Array 2013, the 5th IEEE international symposium presenting advanced in phased array systems and technologies, will be held at the Westin Hotel, Waltham, Massachusetts on Boston’s famous Route 128.
