Introduction

The global expansion of the Internet of Things (IoT) and the ongoing rollout of 5G networks are fundamentally transforming the way wireless communication systems operate, necessitating advancements in antenna technologies [1]. As IoT devices and industrial applications grow in complexity, the need for efficient, reliable, and scalable communication networks becomes more critical [2]. IoT networks consist of a wide range of devices, from sensors and smart appliances to industrial robots and autonomous vehicles, all of which require robust, high-performance wireless connectivity [3]. Simultaneously, 5G networks are designed to provide ultra-reliable, low-latency communication with high throughput, addressing the increasing demand for mobile broadband and mission-critical communications [4]. Traditional antenna systems, which rely on fixed beamforming configurations, are inadequate for handling the dynamic nature of modern wireless environments, leading to inefficiencies and poor performance under varying conditions [5].

The limitations of conventional antennas highlight the need for more intelligent solutions capable of adapting to network changes in real time [6]. Smart antennas, integrated with machine learning (ML) algorithms, represent a significant advancement in this regard [7]. These antennas are designed to continuously optimize their performance based on real-time network conditions, ensuring that signal strength, coverage, and interference management are constantly adjusted [8]. By leveraging ML, smart antennas can autonomously learn from the network environment, improving their ability to handle complex interference patterns, adjust beamforming dynamically, and manage resources efficiently [9]. This flexibility is particularly crucial for IoT and industrial 5G networks, where devices are constantly moving, network traffic is highly variable, and interference is often unpredictable [10].

Machine learning plays a key role in enhancing the capabilities of smart antennas, enabling them to make real-time decisions without the need for manual reconfiguration [11]. Through the use of supervised learning, reinforcement learning, and deep learning, these antennas can analyze large datasets and predict optimal configurations for signal transmission [12]. For example, in beamforming, smart antennas can adjust their directionality and power to ensure the strongest signal reaches the intended receiver, while minimizing interference to other devices in the network [13]. This adaptability not only improves the performance of the antenna system but also maximizes the overall efficiency of the network by reducing the likelihood of congestion and signal degradation [14]. The integration of ML-driven smart antennas ensures that IoT and 5G systems can support a wide range of applications, from data-intensive smart city infrastructure to latency-sensitive industrial automation [15].
