Question
The value of VSWR when the antenna impedance is perfectly matched with Transmission line is _______
Select one:
- a. Infinite
- b. None of the above
- c. 1 dBd
- d. 1
Solution
Break Down the Problem
- We need to determine the value of Voltage Standing Wave Ratio (VSWR) when the impedance of the antenna is perfectly matched with the transmission line.
Relevant Concepts
- The formula for VSWR is given by:
where is the reflection coefficient.
- When the antenna impedance is perfectly matched with the transmission line, the reflection coefficient .
Analysis and Detail
- Substituting into the VSWR formula:
Verify and Summarize
- Since we derived that the VSWR is 1 when the antenna is perfectly matched, we can conclude that this is the correct answer.
Final Answer
The value of VSWR when the antenna impedance is perfectly matched with the transmission line is 1.
