Abstract

A method of obtaining single wire transmission line (440) wherein the use of short wavelengths yields low radiation losses and wherein transmission line losses are compensated by repeaters (19, 213-219) at required intervals.

Claims

1. A transmission line for short wavelengths and low attenuation, comprising:

A wire (440) acting as a transmission line whereby the wave due to the short wavelength is kept trapped near the wire and where transmission line losses are compensated by repeaters (19, 213-219) at required intervals wherein said repeaters allow said conductive wire to be uninterrupted using coupling arrangements (141, 142).

2. A transmission line according to claim 1 where coupling between the transmission line and repeaters (19, 213-219) and connections points (120, 121, 210-212, 221-222) is performed using electric (142) and magnetic field (141) coupling arrangement to said wire.

3. A transmission line according to claim 1 where the repeaters (19, 213-219) are powered by at least one of inductive (141), capacitive (142) and resistive (143) methods from the hosting infrastructure constituted by said wire.

4. A transmission line according to claim 1 where the said transmission line is bidirectional.
