%X 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.
