“…Te master international frequency register (MIFR), which falls under the jurisdiction of ITU-R, is a crucial component of international frequency management services [19]. It serves as a permanent database containing spectrum parameters for radio station operations across the globe, providing global acknowledgment and anti-interference protection [20]. Currently, the database holds over 2.6 million frequency allocations for terrestrial services, with over 200,000 new allocations added every year, managed by radio communication bureau (BR).…”

The review focuses on the emergence of 5G wireless communication and the need for multiple-input multiple-output antennas to support high-speed communication systems. The article discusses the advantages of MIMO antennas, including increased channel capacity and the ability to focus radio frequency energy on specific users. However, the challenges of creating compact MIMO antennas with ideal isolation are addressed, including short wavelengths, connection losses, constrained bandwidth, and path losses in the millimeter-wave range. Design techniques and methods to enhance the performance of conventional antennas for 5G applications are discussed, along with potential solutions for upcoming challenges. The article provides an overview of MIMO antennas for 5G applications, covering frequency bands, system architecture, advantages, challenges, advancements, performance enhancement techniques, design techniques, and state-of-the-art developments.
