Abstract: An UWB MIMO (Multi Input Multi Output) antenna with two notch bands suitable for IOT (Internet of Things) applications is designed in HFSS simulation software and obtained results are presented. To enhance isolation between two CPW feed flag shaped patch antennas etched on common ground is provided with two SRRs (split ring resonators) on either side of feed line, contains a gap between feed line edge to SRR edge of 0.5mm. SRRs also responsible for formation of two notch bands first one is from 5GHz to 8GHz(C-Band) and second one is from 10.4GHz to 10.7GHz (X-Band). Constant peak gain of 4.2dB and radiation efficiency of 89% is maintained throughout the UWB region. Finally simulated results are compared with experimental results, which proves that MIMO diversity antenna is best suitable for IOT applications.
