Abstract

The gain is an important figure of merit to describe the performance of an antenna under test (AUT). For radiation pattern envelope (RPE) measurements or other ad-hoc scans, the realized gain of the AUT is often determined by applying the gain-transfer (gain-comparison) method. The relative measurement values are compared with a measurement of a standard antenna (SGH) with a known gain. Ideally, the gain values of the standard antennas are based on a traceable calibration. But also, the calculated gain of commercially available standard antennas is usually supplied by the manufacturer. However, these values do not necessarily describe the realized gain for the current reference measurement. They may result from different setups or refer to non-identical environmental conditions or on a different gain definition. This paper explains the benefits and limitations of the pattern integration technique, to provide validated reference values of the SGH in the current measurement setup within reasonable time. The results presented are based on measurements in the DLR Compact Test Range
