Question 1
Antenna & Wave PropagationAntenna Fundamentals

The primary function of a transmitting antenna is to convert?

  • AGuided electromagnetic energy into radiated electromagnetic waves
  • BDC power directly into mechanical energy
  • CSound waves into heat only
  • DDigital data into resistance
Report an error
Correct Answer: A. Guided electromagnetic energy into radiated electromagnetic waves
Explanation: A transmitting antenna couples guided RF energy from a transmission system into electromagnetic waves that propagate through space.
