Multiband Compact MIMO Antenna for sub-6 GHz Applications

A multiband compact multiple-input multiple-output (MIMO) antenna system is proposed for sub-6 GHz 5G new radio, LTE, RFID and internet-of-things (IoT). The proposed design has two modified truncated tetrahedron MIMO elements on top of substrate and a slotted tapered ground plane on the bottom of the substrate. This entire system covers multiple bands like 854–958 MHz, 1.38-1.56 GHz, 1.75-1.87 GHz, 2.08-2.49 GHz, 3.29-3.47 GHz and 4.09-6 GHz. The antenna is simulated using CST simulator. The results of simulation are presented in the paper.
