Sources of losses in Transmission lines

The three major sources of losses in RF transmission lines are:

1. Copper Losses:-

(a)    I2 R Losses. This is due to the resistance associated with the conductors constituting the transmission lines or in other words this loss is due to power dissipation as a result of heating in pure resistance .This loss is frequently dependent and increases with increase in frequency .[Resistance associated with transmission line cannot be measured with an ohmmeter because at radio frequencies,RF ,the current tends to flow on the conductor surface  or very near to the conductor surface due to effect called skin effect.
