A cutting-edge Wide-Band MIMO Antenna for Modern Wireless Applications

The present work explores the insights of a design which is defined as an octagonal geometry based four port wideband MIMO antennas for wireless systems. The isolation essentialities have been considered through the parasitic elements (PE) with T-shaped isolation structure for isolation boost. The antenna under consideration is optimized to achieve the best MIMO performance parameters. It has functional band of 2.16-4.30 GHz and the antenna fabricated on substrate size of 60.0 X 76.0 mm2. The gain 3.44 dBi, envelop correlation coefficient (ECC) < 0.03, and mean effective gain (MEG) ≤ -2.90 dB are achieved. The total active reflection coefficient (TARC) bandwidth is found 1.35 GHz. The specific absorption rate and channel capacity loss are evaluated, and both found to be within acceptable limit recommended by international telecommunication union (ITU). The results obtained through the proposed design are found to be within the acceptable limits of stability for effective communication system.
