Question: In calculating the chamber reference transfer function for a fixed antenna in OTA testing, why is the radiation efficiency of the fixed antenna not corrected for?
Option 1: Because its impact on the results is negligible compared to other factors.
Option 2: Since it varies significantly with frequency, correction would be too complex.
Option 3: As it remains constant during both calibration and measurement phases, its effect cancels out in the final results.
Option 4: Because correcting for it would require additional, unspecified measurements.
Explanation: The correct answer is Option 3 because the radiation efficiency of the fixed antenna does not affect the final results since it remains constant throughout both the calibration and measurement processes. This consistency means its impact is effectively neutralized in the calculation of the chamber reference transfer function, making correction for this factor unnecessary for the accuracy of the final outcome.
