Q. The solid area through which all the power radiated by the antenna is:

  • (A) beam area
  • (B) effective area
  • (C) aperture area
  • (D) beam efficiency
💬 Discuss
✅ Correct Answer: (A) beam area
Explanation: the beam area is the solid angle through which all of the power radiated by the antenna would stream if p (θ, φ) maintained its maximum value over beam area and zero elsewhere. this value is approximately equal to the angles subtended by the half power points of the main lobe in the two principal planes.
