Mobile handset performance evaluation using spherical measurements

The mean effective gain (MEG) is an attractive performance measure of mobile handsets, since it incorporates both directional and polarization properties of the handset and environment. We compute the MEG from measured spherical radiation patterns of five different mobile handsets, both in free space and including a human head and shoulder phantom. Different models of the environment allow a comparison of the MEG obtained for realistic models based on measurements with the total radiated power (TRP) and the total isotropic sensitivity (TIS). All the comparisons are based on the MEG values obtained for different orientations of the handsets in the environments.
