Abstract
The work details the development of a two-port arc-shaped Multiple-Input-Multiple-Output (MIMO) antenna with enhanced isolation characteristics. The proposed dual-port MIMO provides a wide impedance bandwidth of 3.28–5.93 GHz and a maximum isolation of 27 dB between elements in the operating frequency band. A reduced ground plane is utilized to obtain the wideband characteristics for the proposed antenna. The major applications covered by the antenna include sub-6 GHz: n77/n78/n79 and WiFi-5 bands. The important MIMO parameters such as Envelope Correlation Coefficient (ECC), Mean Effective Gain (MEG), Diversity Gain (DG) and Total Active Reflection Coefficient (TARC) are presented to estimate the performance of the developed antenna in the MIMO environment.
