Design of the MIMO-UWB antenna for used in multi-frequency in wireless communication systems with the application of Marine & aerial devices

In this paper, the microstrip antenna design with the MIMO model in the UWB frequency band is discussed. Innovations in this research have established the frequency band WiMAX and WLan, and reduced the rate of Isolation and recurrence losses of the antenna and increased the gain and bandwidth in noise-free environments. The bandwidth of the antenna is 1GHz to 30GHz. WiMAX has Notch Band in the bandwidth at 3.3GHz to 3.7GHz. Wlan has Notch Band in the bandwidth at 5.1GHz to 5.9GHz. The S11 = -10dB, VSWR <; 2, S12 <; -20dB. Diversity coefficient=10. The substrate of material is FR4 and dimensions of 60*96mm with a thickness of 0.8mm and a relative permeability of 4.4. Of the plate is 60 * 75mm. This design is done using the CST STUDIO SUITE software.
