Abstract This paper presents an idea for the average brightness temperature of antenna aperture and its expression for a lossless antenna with matched and unmatched noise sources. The expressions show that the average brightness temperature of antenna aperture relates with three factors: coefficient of useful area for antenna, noise temperature of noise sources and reflective coefficient of noise sources.

Key words： Antenna aperture Brightness temperature Noise temperature Reflective coefficient Coefficient of useful area
