Abstract :
This paper investigates various designs of 4-element miniaturized Planar Inverted-F Antennas (PIFA) with pattern and polarization diversity at 2.45 GHz. The antennas are only 13mm x 7mm in area and built on a small ground plane size of 105 mm x 55 mm. Diversity performance criteria namely the Envelope Correlation Coefficient (ECC) and Mean Effective Gain (MEG) are computed for different fading channel scenarios using the simulated far-field radiation patterns. Then the Effective Diversity Gain (EDG) of all the configurations under the Maximal Ratio Combining (MRC) scheme are generated. The results show that the antenna systems can give a maximum EDG of 16.31 dB as compared to the theoretical limit of 19.12 dB.
