Question

In which of the following method does not require standard gain of antennas for gain measurements to compare AUT?

(a) Absolute gain

(b) Gain transfer method

(c) Gain compromise method

(d) Both gain transfer and absolute gain method

This question was addressed to me in an interview.

Origin of the question is Measurement of Gain in portion Modern Antennas & Antenna Measurements of Antennas

Answer 1

Correct choice is (a) Absolute gain

For explanation: Gain transfer and gain compromise methods require the standard gain calibration of antennas for gain measurements to compare the antennas under test. In Absolute gain method, gain of the antennas which are to be compared are known priory and this is used for the standard gain calibration
