Old Marconi Patent Inspires Tiny New Gigahertz Antenna

agent elevator writes Gehan Amaratunga and a group of engineers in England noted that the Guglielmo Marconi's famous British patent application from 1900 had an interesting and little noticed detail. It depicted a transmitter linked to an antenna connected to a coil, which had one end dangling while the RF signal was fed to the middle of the coil. That detail inspired them to develop a way to reduce the size of a GHz antenna without significant transmission loss by using dielectrics as the radio wave emitting material instead of conductors.

    I read the title as "old macaroni patent" on first glance.
