. FR-4 substrate is used for fabrication process having loss tangent and dielectric constant are 0.02 and 4.3 respectively. The presented antenna working in operating set of radio frequencies 2.4GHz-2.7GHz and 4.3GHz-7.0GHz to meet Zigbee, Bluetooth, and WLAN applications, the desired frequency bands are achieved by combining inserting Stair case structure below the arrow head shaped structure. In this MIMO antenna design process, it is noted that there is improved isolation when the modules of antenna are deposited in orthographic positions as compared to the elements placed in parallel positions. The isolation of the proposed Multi Input Multi Output antenna is less than −17dB in operating band of frequencies. Spatial multiplexing is used in the design process to emphasize the capacity of the channel to carry the data. The diversity parameters like DG, MEG ECC, CCL and TARC are calculated and observed that the theoretical values are matched with the practical values. In this paper, Envelope correlation coefficient (ECC) <0.09 is obtained for proposed frequencies. The initiated antenna designing and execution are done with the help of 3D EM simulation software.
