A Broadband MIMO Antenna for UWB Applications

Abstract

This paper presents 2  2 multiple-input multiple-output (MIMO) antennas covering UWB wireless applications like portable handset devices, mobile phones, and Bluetooth devices. The overall wide bandwidth of the proposed antenna is 2.4 GHz - 7.3 GHz. The proposed antenna’s bandwidth covers different bands of WiMAX and WLAN applications, and it gives better isolation in close space. A U-shaped patch antenna is simulated on the Rogers substrate, to achieve the antenna’s broadband features, the size of the proposed antenna is (28.79 x 18.79) . The achieved isolation, highest gain, and the total efficiency of the 2 x 2 MIMO network is -23dB, 6dBi, and 95% respectively.
