UWB MIMO ANTENNA FOR INTERFERENCE REDUCTION IN WIRELESS COMMUNICATIONS
摘要
A novel ultra-wide band (UWB) multi input multi output (MIMO) antenna is proposed for interference reduction in wireless communications. A band notch antenna is presented with a compact size of 22 × 36 mm2 for decreasing interference between UWB and WLAN bands. The antenna contains of two square monopole-antenna elements, a T-shaped ground stub, a vertical slot cut on the T-shaped ground stub to decrease mutual coupling, and two strips on the ground plane to create a notched frequency band. The presented antenna can be used for portable UWB applications. The proposed antenna is designed and simulated using electromagnetic software CST Microwave Studio and the results show that the antenna operates in the frequency range from 3.1 to 10 GHz with a notch in WLAN 5.15 to 5.85 GHz frequency. The antenna is fabricated and the comparison is made between measured and simulated results. The results show that the MIMO antenna is well suited for portable UWB applications.
