System and method for determining gain characteristics of a circularly-polarized antenna. The method includes receiving a measured first amplitude of a forward gain between a circularly-polarized antenna probe of a first type and a linearly-polarized standard-gain antenna, a measured second amplitude of a forward gain between a circularly-polarized antenna probe of a first type and a circularly-polarized antenna under test, and a measured third amplitude of a forward gain between a circularly-polarized antenna probe of a second type and the circularly-polarized antenna under test. The method also includes determining a left-hand circularly-polarized gain and a right-hand circularly-polarized gain of the circularly-polarized antenna under test based on the measured first amplitude, the measured second amplitude, the measured third amplitude, and a cross-polarization level of the circularly-polarized antenna probes of the first and second types. The determination may be performed using one or more processors.
