Abstract
The gain calibration value of the standard gain antenna is the reference baseline of the unknown gain antenna measurement, which determines the accuracy of the measured antenna gain measurement. This paper introduces a method of measuring antenna gain without standard gain antenna. Taking horn antenna as an example, a set of antenna measurement system with unknown gain is established in microwave darkroom by using three pairs of horn antenna, vector network analyzer, tripod and other equipment. Taking one antenna as a reference, the gain values of the other two antennas are measured respectively, and the actual measured values are compared with the gain values in the antenna manual. The gain deviation is within a reasonable range, which shows that the method is reasonable and feasible when there is no standard gain antenna.
