Multiple-input multiple-output (MIMO) antennas are materialized to be a critical technology for achieving high data concerns and improved network competence in fifth generation (5G) wireless communication systems. The implementation of MIMO technology in 5G systems requires the development of compact and efficient antenna systems that can support many antennas as a single system or module. MIMO antennas can provide spatial diversity and multiplexing, which can adjust the reliability, robustness, and competence of the wireless communication systems. MIMO systems help to achieve increased performance in conditions of data rate and link reliability. The proposed 1 X 2 MIMO antenna design operates at a frequency spectrum range of 5 to 7 GHz, which is commonly utilized in various wireless communication applications as well as other domains like Internet of Things (IoT) applications. The antenna materials are made of copper and are designed on a FR4 substrate with a dielectric constant of 4.4 and a thickness ranging of 1.6 mm. The emanating constituents are designed in such a way that they can achieve a compact and efficient antenna design. Feeding network of the multiple antenna system is vital and does complex performance. The feeding network splits the input signal equally into two signals, which are then fed to the radiating foundations of both antennas. It also helps to combine the signals received by the radiating elements of both antennas, resulting in an overall improvement in the received signal strength. The implementation of the anticipated MIMO antenna design is evaluated in terms of the return loss, radiation pattern, and segregation between the antennas. The findings are viewed such that the anticipated MIMO antenna design needs low return loss, omnidirectional radiation pattern, and high isolation between the antennas, achieving it appropriate for wireless communication purposes. The proposed design is simple and cost-effective, making it easy to integrate into several wireless communication systems. The antenna can be further optimized for specific applications, such as IoT devices, mobile communications, or wireless sensor networks, by adjusting the frequency range, substrate material, or antenna dimensions.
