Maximizing Performance Enhancement of MIMO Array Antennas through Innovative Two-Element Array Configuration: A Comparative Analysis with Single-Element Rectangular Microstrip Patch Antennas

The use of a novel two-element array configuration, this work seeks to increase the gain of a microstrip patch MIMO array antenna relative to that of a single element patch antenna. Gain and Return loss measured for different frequencies and values are compared with a single element patch antenna. Materials And Methods: Novel two element MIMO array antenna is designed and compared with a Single element patch antenna. In this work, there are two groups (Two element patch & Single element patch) each consisting of 20 samples with pre-test power or G-power of 80%. Results: Experiment results indicated an improved Gain (dB), Return loss (dB) using the MIMO Novel two element patch antenna and compared with the single element antenna. These results showed that the microstrip Novel two element array exhibited a higher Gain and better Return loss. The mean Return loss in the Novel two element MIMO array antenna is −22.53 dB and in the Single element patch antenna is −15.21 dB and with the two-tailed significance of (p < 0.05). Conclusion: The gain improvement is significantly better in a Novel two element array antenna when compared with a Single element patch antenna.
