Abstract
Over a hundred years later, the classic antenna, first invented by Heinrich Hertz, in 1888, <xref ref-type="bibr" rid="ref1" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">[1]</xref> , is still the dominant technology used for the measurement of RF fields. Just seven years after its invention, Guglielmo Marconi applied the antenna to long-distance radio communication and, in the process, transformed the global community into one connected civilization <xref ref-type="bibr" rid="ref2" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">[2]</xref> . It is clear that the antenna has been a powerful piece of technology. What reason would we have, then, to use anything different?
