Abstract

This study presents a comprehensive discussion on a Quad port Fractal Multi Input Multi Output(MIMO) antenna incorporating Split Ring Resonator (SRR) technology. The use of Multiple-InputMultiple-Output (MIMO) antennas in wireless applications is a basic technological advancement withthe objective of augmenting both the channel capacity and data rates. Multiple Input Multiple Output(MIMO) antenna technology is widely used in various applications to improve wireless communicationperformance. One crucial concern associated with Multiple-Input Multiple-Output (MIMO) technologyis to the limitations imposed by spatial constraints and the design of antenna elements. The performanceof MIMO antennas is diminished as a result of strong signal correlation, which is attributed to theirnear proximity. The main challenge in the development of MIMO antennas is in achieving reducedmutual coupling. The MIMO antenna has been designed specifically to function in four distinctfrequency bands, including lower WiMax, middle WiMax, Satellite TV, and X-Band applications. Theantenna under consideration has satisfactory S-parameter values, a low envelope correlationcoefficient, and Total Active Reflection Coefficient (TARC) throughout the four frequency bands. Theenvelope correlation coefficient for the planned multiple-input multiple-output (MIMO) antenna isfound to be below 0.05. Envelope Correlation Coefficient is essential in designing efficient MIMOsystems, ensuring reliable and high-performance wireless communication.
