Performance analysis of PIFA based 4 x 4 MIMO antenna

Presented is the design of a planar inverted-F antenna (PIFA) based 4×4 MIMO antenna working in the frequency range 2.4×2.8×GHz, along with its various performance measure parameters such as MEG (mean effective gain), correlation coefficient, TARC and channel capacity, that are calculated using simulation results and presented here for street grid communication applications. The aim of this design is to develop a wideband, compact and low profile MIMO antenna configuration which can be integrated easily with the rest of the system. The calculated value of MEG for all the antennas is around ×3.5×dB, the envelope correlation coefficient is less than 0.5 in all cases, the average TARC calculated using measured S-parameters is around ×7×dB in the desired frequency range, and the calculated channel capacity for the street grid urban scenario is 22×bits/s/Hz at 30×dB SNR.
