Q. A rectangular horn antenna has an aperture area of 3λ × 2λ. If the aperture efficiency of an antenna is 90%, then the directivity of the antenna is:

  • (A) 19 db
  • (B) 17.1 db
  • (C) 13 db
  • (D) 21.1 db

Explanation by: Admin

given the aperture dimensions of an antenna, the directivity that can be achieved is ap4π a/λ2, where a is the aperture area and λ is the operating
