Abstract

Abstract:

In order to further expand the application field of GTEM cell, a method of testing a total radiation power (TRP) in GTEM cell is proposed according to the characteristics of GTEM cell. The equivalent electric dipole moment (EDM) and magnetic dipole moment (MDM) are inverted through the testing in GTEM cell, the results by |S11| parameter are compensated, and the EUT’s TRP testing results are calculated. Experiments show that this method for new TRP testing and its compensation are simple and accurate, it has a practical value in wireless devices testing in some major social activities and small antenna’s performance testing.

Key words: Gigahertz transverse electromagnetic cell； total radiated power； , S11, parameter
