Coaxial cable, or
coax, has an inner conductor surrounded by a flexible, tubular insulating layer, surrounded by a tubular conducting shield. The term
coaxial comes from the inner conductor and the outer shield sharing the same geometric axis. Coaxial cable was invented by English engineer
and mathematician
Oliver Heaviside, who patented the design in 1880.
[1] Coaxial cable differs from other
shielded cable used for carrying lower-frequency signals, such as
audio signals, in that the dimensions of the cable are controlled to give a precise, constant conductor spacing, which is needed for it to function efficiently as a radio frequency
transmission line.
