Antenna & Wave PropagationAntenna Pattern Parameters

The front-to-back ratio of a directional antenna compares radiation in the main-beam direction with radiation?

  • AIn the opposite direction
  • BAt the half-power point
  • CAt 90 degrees only
  • DAt the feed terminals
Report an error
Correct Answer: A. In the opposite direction
Explanation: Front-to-back ratio compares forward radiation with radiation approximately 180 degrees behind the main beam.
