Pattern, gain and temperature measurements of reflector antennas

The authors present an overview of results for far field pattern, antenna gain, and antenna temperature measurements of reflector antennas in several frequency bands. The pattern and gain measurements were taken in the compact range at the Ohio State University. In a series of related measurements an 8 ft diameter Cassegrain reflector was used for antenna temperature measurements under clear weather conditions in an outdoor environment. The measured patterns have been compared with patterns calculated by the Ohio State University Reflector Antenna Code. The quality of the measured patterns and the good agreement between the measured and the calculated patterns demonstrate the utility of the compact range facility for antenna measurements and the accuracy of the code used.<>
