Consider a transmission line of characteristics impedance

Home » Electromagnetic Theory » Electromagnetic theory miscellaneous » Question

Consider a transmission line of characteristics impedance 50 ohm. Let it be terminated at one end by + j 50 ohm. The VSWR produced by it in the transmission line will be—

1. + 1
2. 0
3. ∞
4. + j

Correct Option: C

Reflection coefficient is given by

ρ =		Z_L − Z₀	=	j 50 − 50
		Z_L + Z₀		j 50 + 50

Hence |ρ| =
√(50² + 50²)/ √(50² + 50²)

and the VSWR =	1 + \|ρ\|	=	2	= ∞
	1 − \|ρ\|		0
