%X MIMO systems where multipath fading is only
partially correlated could use polarization diversity to provide
a higher diversity gain. Recent letters have proposed the use of
tri-polarized antennas and a novel true polarization diversity
(TPD) scheme. In this paper, the full potential of TPD is evaluated
with both simulations and measurements and compared
to conventional orthogonal polarization diversity (OPD). MIMO
system performance with respect to capacity and diversity gain is
obtained through the use of multimode-stirred chambers for both
isotropic and non-isotropic environments. Simulated and measured
results in over 591 different MIMO systems show that TPD
outperforms conventional OPD for reduced volumes. Likewise, it
has been demonstrated that TPD can be effectively combined with
spatial diversity to nearly double the diversity gain and MIMO
capacity for the same available handset volume.
