The most important technical advance in the 1930s was, in the opinion of the writer, the invention of the resonant slot. This was a device which was both an aperture radiator and a resonant structure. Its novelty was major. Nothing as important had appeared since Hertz invented the dipole and the loop and Lodge and Bose experimented with open-ended waveguide radiators. The words are from Ramsay [1]. He mentions in particular Alan D. Blumlein at EMI Central Research Laboratories in the UK as the inventor of the resonant slot antenna (patent no. GB 515684, 1938). Blumlein also proposed linear arrays of slots.
