Show AnswerHide Answer Report an error

Correct Answer: A. Noise power received from the environment through its radiation pattern

Explanation: Antenna noise temperature represents environmental noise collected by the antenna, weighted by its directional response.

Reference: Standard antenna and wave propagation: antenna noise

Question 2
