That document treated antenna gain as a fundamental property, with impedance and polarization as independent properties. The definitions of gain, directivity, impedance, and polarization were worded to emphasize this independence. Various other significant groups of terms were also defined, such as the regions of the electromagnetic field of an antenna, the terms relating to cross section, the tracking antenna techniques, and the idealized radiators. 517 $aIEEE No 145-1973 606 $aAntennas 615 0$aAntennas. 676 $a621.3824 801 0$bNjHacI 801 1$bNjHacl 906 $aDOCUMENT 912 $a9910137364003321 996 $aIEEE No 145-1973$93646978 997 $aUNINA
