Posted on by Engr. Hamid Ali

Q. If Voltage Standing Wave Ratio, (VSWR) of a wave is 2, its reflection coefficient will be

a. 0

b. 1/3

c. 1/4

d. 1/2

Answer and Explanation:

Answer is 1/3.

The relationship between Voltage Standing Wave Ratio (VSWR) and Reflection Coefficient is given by the Following Equations
SWR=( 1+Γ )/ (1-Γ )—————1

and

Γ= (SWR -1)/( SWR +1) ————-2

From 2 by putting SWR= 2 we will get Γ=1/3
