Reflected signal on a no uniform overhead transmission line at high frequency

Abstract EN

The effect of the sag of an overhead transmission line is numerically characterized in the case of two conductors above lossy earth at high frequency.

The technique uses the chain ABCD matrix for a transmission line of two conductors above ground and we present a generalized recurrence formulation of the reported input matrix impedance for a finite length section of multiconductor transmission line.

Then the nonuniform transmission line can be subdivised into sections of uniform transmission line.

This technique is used to calculate input impedance and reflection coefficient of an incurved overhead two-conductor transmission line over the 1-30MHz range.
