Single wire transmission line used to conduct radio waves at UHF and microwave frequencies
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]
