Anyway, that was Peter's own explanation of why he gave the name. Vivaldi had written a trumpet concerto, and it was the 300th anniversary of Vivaldi’s birth in 1678. He told me that he called the tapered slot antenna a "Vivaldi" as it looked like the cross-section of an early trumpet. Peter was really into music, composing pieces, teaching piano in those days and was a church organist. After that I kept in contact with him through to his retirement and eventually his death. I knew Peter as I worked with him at Philips Research Laboratories UK from 1983 through to when he left in the late 1980s. But we received a better explanation of his choice of name for the tapered slot antenna, from another Peter who worked with him: Update February 2012: We are sad to report that Peter Gibson died in 2010. If you ask an antenna engineer where the name came from, chances are he'll tell you Vivaldi was the inventor. Gibson never said why he named his innovative antenna the "Vivaldi" aerial in the paper. New for March 2012: Peter Gibson now appears in our Microwave Hall of Fame! New for October 2013: we describe egg crate construction. In the abstract he describes it as "a new member of the class of aperiodic continuously scaled antenna structures, as such, it has theoretically unlimited instantaneous bandwidth." Gibson in a paper entitled The Vivaldi Aerial. The Vivaldi antenna was first discussed in a 1979 IEEE European Microwave Conference paper by P. Peter Gibson invented the Vivaldi antenna in 1978, in the UK. The Vivaldi antenna, sometimes referred to as or the Vivaldi notch antenna, and also known as the tapered slot antenna (TSA), is easy to fabricate on a circuit board, and can provide ultra-wide wide bandwidth.
