Extra exam question E9G01
Subelement E9, ANTENNAS AND TRANSMISSION LINES· Group E9G
Which of the following can be calculated using a Smith chart?
- A.Impedance along transmission lines (correct answer)
- B.Radiation resistance
- C.Antenna radiation pattern
- D.Radio propagation
WhyA Smith chart can be used to calculate impedance along transmission lines. A Smith chart can be used to calculate how impedance transforms along a transmission line, tracking how a load impedance appears different at various points back toward the source depending on the line's electrical length, one of its core original uses, answer A. It isn't used to calculate radiation resistance, antenna radiation patterns, or radio propagation, those are separate antenna and propagation topics a Smith chart doesn't address.
