Simulation study of Four Element MIMO Antenna System with Pattern and Polarization Diversity

In this paper, two configurations of previous work are extensively studied, namely pattern diversity and hybrid (pattern and polarization) diversity configuration. The first configuration provides the pattern diversity whereas second configuration provides both the pattern as well as the polarization diversity which helps to mitigate the multipath propagation effect. Both the configurations are designed over a small ground plane of size 100 × 60 × 0.8 mm 3 . The isolations between antenna elements for both the configurations are better than -12 dB. The performances of both configurations are evaluated through S-parameters and radiation patterns. The diversity parameters namely, envelope correlation coefficient (ECC) and mean effective gain (MEG) are also studied. Keywords— ECC, MEG, pattern diversity, PIFA, polarization diversity.
