Abstract

The conclusion that an antenna´s amplitude receiving pattern (ARP) and its amplitude transmitting pattern (ATP) are equal obtained from the electromagnetic field reciprocity principle has premises easily ignored. Analysis on received polarization electromagnetic wave shows that the above conclusion is queried. The antenna under test (AUT) will be faced with different polarization mismatching status of itself and the testing antenna in reception or transmission, so that the form of ARP and ATP are generally not equal. Therefore, the reciprocity between ARP and ATP of AUT is not tenable. Lastly, correct pattern measurement of linear and circular polarization antenna is given.
