Antenna & Wave PropagationYagi-Uda Antenna

Adding suitably designed directors to a Yagi-Uda antenna generally tends to?

  • AIncrease directivity in the forward direction
  • BMake it perfectly isotropic
  • CEliminate all impedance
  • DForce radiation only backward
Report an error
Correct Answer: A. Increase directivity in the forward direction
Explanation: Directors concentrate radiation in the forward direction and can increase Yagi-Uda directivity.
Reference: Standard antenna and wave propagation: yagi-uda antenna
