Abstract: In this articlea band notched multiple-input-multiple-output (MIMO) antenna with improved isolation is presented. The proposed antenna consists of a semi square split ring resonator (SRR) which is slotted on the two flag shaped patches. Two inverted semi square SRR are placed in the patch to get notch at WIMAX band (3.3GHz-3.8GHz) throughout the band the isolation is above 11db is observed and it is achieved with the placement of T-shaped stub on the ground plane. Proposed antenna is fabricated on FR4 epoxy substrate and simulated and measured results have been verified. The proposed antenna works at WLAN band (at 5.64GHz) and satellite communication (at 7.42GHz). In respect to this the envelope correlation coefficient (ECC), diversity gain (DG) and radiation patterns are discussed.
