Abstract
An electromagnetic wave radiation coaxial cable and a communication system using the same. The electromagnetic wave radiation coaxial cable includes an inner conductor which is formed of a conductor and extends along a cable axis, an insulator covering the inner conductor, and an outer conductor spirally wound around the insulator in a single winding at a predetermined pitch to provide a gap from which a part of the insulator is exposed. Following formula is established: when λ is a wavelength of a radio frequency signal to be transmitted or received, ∈is a relative dielectric constant of the insulator at the wavelength λ, and P is a winding pitch of the outer conductor along the direction of the cable axis.
