ABSTRACT

In today’s communication networks. The IoT (Internet of Things) plays a major part in this. In this present and future communication paradigm, hundreds of different smart ‘internet enabled’ devices will link with one another continually. Aside from protocols of sophisticated communication, such communication networks and smart devices will require efficient hardware. Because they are at the front end of communication, antennas are one of the most crucial components of such hardware. For applications like IoT, antennas must have three key characteristics: small in size, energy efficiency, and the capacity to operate in an environment of multiple antennas. In this study, we describe a design of antenna that achieves these important requirements. 5G communications are likely to include MIMO, which will necessitate antennas with a large number of elements. However, maintaining strong isolation between ports is difficult due to the size constraint. With use of HFSS software, we built a MIMO antenna having improved isolation. An efficient four-element mm-Wave MIMO (multiple-input multiple-output) antenna being proposed for use in a 5G system.

For 5G (fifth generation) new radio applications for future IoT applications, a MIMO antenna system capable of operating in frequency spectra of between 2.25GHz and 3.0GHz been proposed. This study proposes MIMO antenna designs for IoT applications with an overall dimension of 40x 80x1.5mm3. The suggested MIMO antenna is made of a 1.6mm thin FR4 having constant of dielectric as 4.4 with loss tangent equal to 0.02. The maximum efficiency of the recommended antenna at 2.4GHz is 83%. Comparison of measured as well as simulation results should show that the suggested design meets the intended criteria, namely, isolation greater than 12dB, overall efficiency greater than 48%, and envelope correlation coefficient of 0.07. Radiation pattern, realized gain, total efficiency and channel capacity is all examined as well.
