Question

Which of the following is used mostly for the calibration of standard gain of antenna?

(a) Absolute gain

(b) Gain transfer method

(c) Gain compromise method

(d) Both gain transfer and absolute gain method

I have been asked this question in semester exam.

Question is from Measurement of Gain topic in division Modern Antennas & Antenna Measurements of Antennas

Answer 1

The correct option is (a) Absolute gain

To explain: In absolute gain method, the prior knowledge of gain of antennas used in the measurements is not necessary and it is used for standard gain calibration. Gain transfer or Gain compromise method requires the standard gains of the antennas used for measurements to compare the AUT.
