Antenna & Wave PropagationEffective Aperture

For a receiving antenna, effective aperture Ae and gain G are related by?

  • AAe = G lambda²/(4 pi)
  • BAe = 4 pi G/lambda²
  • CAe = G/(4 pi lambda²)
  • DAe = lambda/(4 pi G)
Report an error
Correct Answer: A. Ae = G lambda²/(4 pi)
Explanation: For a matched receiving antenna, effective aperture is related to gain by Ae=Gλ²/(4π).
Reference: Standard antenna and wave propagation: effective aperture
