Loss in transmission line
WebReturn loss. In telecommunications, return loss is a measure in relative terms of the power of the signal reflected by a discontinuity in a transmission line or optical fiber. This discontinuity can be caused by a mismatch between the termination or load connected to the line and the characteristic impedance of the line.

WebSo, for low-loss transmission lines: Propagation loss, α ≈ L C 2 ( R L + G C) Propagation delay, β ≈ j ω L C. If there is no reflection, then the voltage at a point l along the transmission line is: V ( l) = V 0 e − γ l. In this equation, the β portion of the propagation constant γ corresponds to a delay of t p d ≡ L C l.

WebThere are generally 3 types of losses in a Tx line : Radiation loss: The radiation loss is due to electromagnetic field around the conductors. This loss of energy is proportional to the square of the frequency and also depends on the spacing between the conductors. These are more in open wire lines than that in co-axial cables.
