Abstract

This paper presents the design and performance analysis of multiband dual diversity 8-element multiple-input multiple-output (MIMO) antenna at 2.45/3.5/5.2/6 GHz. The proposed antenna was designed on a Flame Resistant (FR-4) substrate having a dielectric constant of 4.4 , dimensions of . The antenna was simulated and analyzed using Computer Simulation Studio (CST Studio). Results obtained from simulation showed that the 8-element MIMO antenna achieved a combined bandwidth of 908.68 MHz representing 34.51% of the fractional bandwidth. Broadside radiation pattern was observed across the three frequency bands in both E- and H-plane with average main lobe magnitude of 7.8 dBi. Furthermore, proposed antenna achieved consistent Envelop Correlation Coefficient (ECC) and Diversity Gain (DG) values of 0.0008 and 9.999 as well as Port-to-port isolation of 27 dB across all frequencies considered. Also, an antenna gain of 8.58 dB was achieved at a frequency of 6 GHz. The gain, isolation, DG and ECC between adjacent ports as well as the loss in capacity were within the standard margins, making the antenna structure suitable for MIMO applications.
