CALIBRATION OF STANDARD GAIN ANTENNAS FOR THE OHIO STATE UNIVERSITY SATELLITE COMMUNICATIONS FACILITY. VOLUME II. A GAIN CALIBRATION STANDARD ANTENNA.
Abstract
The gains of a pair of three-foot paraboloidal antennas were calibrated by the absolute-gain technique and by the gain-comparison technique. The results of the two techniques are in agreement. The gain of the paraboloidal antenna is 34.80 plus or minus 0.20 dB at 7.3 GHz, and 35.48 plus or minus 0.20 dB at 7.95 GHz with a 90.0 per cent confidence level. Because of the close agreement of the results obtained by the two independent measurement techniques one of the paraboloids will be used as a gain-calibration standard antenna. The characteristics of this antenna, the methods of measurements, the experimental setups, and the accuracy considerations are also described. The lower and upper bounds on the confidence level for the measured gain to be within a given range from the mean value for the gain are evaluated in the Appendix. (Author)
