Wireless-enabled gadgets pack a lot of functionality into a small package, which necessitates much bandwidth for speedier data transfer. This paper discusses the characteristics of two-element multiple-input and multiple output (MIMO) antenna systems operating in ultra-wideband (UWB). The close proximity of the antenna components results in high mutual coupling. The unique chain-structured parasitic element is introduced on the radiator to enhance isolation and acts as a decoupling structure. The physical dimension o of the substrate is 21.5×34×1.6 mm3. The addition of a decoupling structure enhances isolation by more than 15 dB for the working frequency range of 4.5-13 GHz. Additionally, the diversity characteristics of MIMO are examined, (Envelope Correlation Coefficient (ECC)<-0.05 dB, Mean Effective Gain (MEG)<-3dB, Total Active reflection coefficient (TARC) <-10 dB ratio, and CCL< 0.4 bps/Hz outcome confirming that the suggested MIMO architecture is well-suited for applications involving wireless communication.

This paper describes a two-port MIMO antenna with a neutralization line as a decoupling structure that operates in the UWB band. The unique chain-structured parasitic element form decoupling structure that links both antenna elements improves isolation between the antenna elements. The decoupling structure in the projected design creates an identical current having out of phase compared to the exciting antenna. Therefore it cancels the mutual coupling between antennas. The projected antenna shows stable radiation properties. Furthermore, the MIMO diversity parameters results verify that the MIMO antenna is suitable for the wireless communication system.
