Born in Cadix, Spain, Juan Rlosig obtained his Diploma of Telecommunications Engineer in 1973 at the Polytechnic University of Madrid. In 1975, he received a Fellowship from the Swiss Confederation to carry out advanced studies at the then Electromagnetism and Microwaves Chair of EPFL. He worked on the design and analysis of microwave printed structures and, supported by the Hasler Foundation and the Swiss National Fund for Scientific Research, originated a new direction for research that is still being strongly pursued.

N2 - A fractal is a recursively generated object having a fractional dimension. Many objects, including antennas, can be designed using the recursive nature of a fractal. In this article, we provide a comprehensive overview of recent developments in the field of fractal antenna engineering, with particular emphasis placed on the theory and design of fractal arrays. We introduce some important properties of fractal arrays, including the frequency-independent multi-band characteristics, schemes for realizing low-sidelobe designs, systematic approaches to thinning, and the ability to develop rapid beam-forming algorithms by exploiting the recursive nature of fractals. These arrays have fractional dimensions that are found from the generating subarray used to recursively create the fractal array. Our research is in its infancy, but the results so far are intriguing, and may have future practical applications.
