A Slotted Hexagonal 4×4 MIMO Antenna with Tapered feed Designed for High Speed IoT Wireless Applications

This research aims for four-port MIMO antenna with very condensed size of 30×30 mm2 printed on RogersRTDuroid5880 substrate. The high speed performance of the antenna is applicable for IoT applications. The antenna is characterized in far-field with gainmax of 3.89dBi and total radiating-efficiency of 74.71%. The antenna covers wider bandwidth of 5.02GHz-13.42GHz which also makes it suitable for UWB-X band applications. The diversity key parameters such as ECC, DG, TARC and CLL are evaluated.
