MIMO Antenna System for IoT Applications (5G)

Multiple Input Multiple Output MIMO, which may be utilized in 5G and IoT networks, is a type of multiple output antenna (IoT). The antenna’s four spatial orthogonal antenna elements are powered by a total of four coaxial cables, two of which are in one plane and the other two in the other. Inverted L-monopoles and grounded stubs are used to build all of the antennas. L-monopoles have a wide range of resonance frequencies that may be tuned to suit the application. Additional resonant frequency modes can be generated by using long grounded stubs. It is possible to use the adjustable 2-element folding meandered MIMO antenna in the 2.4 GHz and 5.8 GHz long-term evolution (LTE) as well as radio frequency identification (RFID) bands (687 MHz-813 MHz). MIMO antennas in the 754 MHz - 971 MHz, 1.65 GHz-1.83GHz, 2GHz3.66GHz and 5.1GHz-5.6Ghz bands are supported by the extra two-element small antennas. It is used in the cognitive radio (CR) environment as a ground plane for MIMO elements in the frequency ranges of 0.668 GHz to 1.94 GHz and 3 GHz to 4.6 GHZ to perform spectrum sensing. 65mm x 120mm x 1.56mm of low-cost FR-4 are used to construct the antenna. In full-wave simulations, the antenna’s radiation characteristics match those anticipated in the simulation. MIMO antennas’ 3D radiation pattern-based envelope correlation coefficient (ECC) was found to be less than half of the projected value. The suggested MIMO antenna’s low profile, compact size, light weight, and ease of integration with wireless communication equipment may be advantageous to IoT systems and modules.
