  • Question

  • Consider a loss less antenna with a directive gain of + 6 dB. If 1 mW of power is fed to it the total power radiated by the antenna will be


  • Options
  • A. 4 mW
  • B. 1 mW
  • C. 7 mW
  • D. 1/4 mW

  • Correct Answer
  • 4 mW 

    Explanation
    6 dB = 10 log10 Consider a loss less antenna with a directive gain of + 6 dB. If 1 mW of power is fed to it the tota

    ⟹Consider a loss less antenna with a directive gain of + 6 dB. If 1 mW of power is fed to it the tota = 100.6 ⟹ 3.98

    Pr = 3.98 mW.
