John, We could not find any well-cited or commonly known circumstances in a related field (to remote sensing) where the antenna temperature can mean "the temperature of the antenna itself." Maybe you could suggest a case where antenna temperature has such a meaning in terms of measurements so we can identify a potential conflict. As far as we can tell, antenna temperature is used to "relate the power emitted by [a] source to an interesting physical property of that source." [http://map.gsfc.nasa.gov/site/glossary.html]
