Goubau line

A Goubau line or Sommerfeld–Goubau line,[1] or G-line for short, is a single-wire transmission line used to conduct radio waves at UHF and microwave frequencies.[2][3][4] The dielectric coated transmission line was invented by F. Harms[5] in 1907 and George J. E. Goubau[6] in 1950, based on work on surface waves on wires from 1899 by Arnold Sommerfeld.[7][8] It is used as a feedline at UHF to link high frequency transmitters and receivers to their antennas,[2][3] and in scientific research.[8]
