Abstract: In this paper A dual band notched MIMO antennais designed with defected ground structure as ground plane and its characteristics are analyzed. The antenna covers UWB frequency ranging from 3.1-10.6 GHz with single notch band characteristics with maximum gain of 3.7 dB. The antenna provides radiation efficiency of 94% with front to back to ratio of 64%. The simulated studied is carried for many frequency band applications. The designed antenna shows patterns similar to that of a the dipole. The substrate used to design this antenna is FR4 withdimensions of 26mm x40mmx1.6mm and dielectric constant of 4.4.The notch bands are at WLAN and WiMax frequencies.
