Four Element Pattern Diversity MIMO antenna with Parasitic Decoupling structure and SRR WLAN notch for UWB application

A UWB 4-element antenna with SRR WLAN notch and four L-shaped parasitic decoupling is discussed. The proposed antennas impedance bandwidth of 10dB varies from 3.8 GHz to 11 GHz and is operated on 5G and UWB applications. The four L-shaped parasitic strip is used to enrich the isolation more than 20 dB. The highest gain of antenna is measured to be 4.5 dB. The SRR notch placed near to the feed is used to prevent the interference with WLAN frequencies and varies from 5.05 to 5.88 GHz.
