Smart Antenna Optimization Techniques for Wireless Applications

Dear colleagues,

In recent years, antenna design has received a lot of attention. This is due to a surge in interest in a variety of applications, ranging from IoT to low-frequency, long-range applications to high-frequency mmWave 5G mobile technology. Wearable antennas that build body area networks have also sparked interest. Wearable clothes and materials that adhere directly to the skin, such as e-skin, are examples of this. The supply of even larger data rates to mobile customers, the delivery of zero-latency multimedia content, and the connectivity of diverse services are all intimately linked on the path to designing and implementing next-generation broadband wireless networks. The goal is to create a cellular network environment in which sensors, appliances, automobiles, and drones may interact with one another. The cellular network's capacity must be considerably increased in order to support such interactions. The notion of 5G, a new generation of mobile wireless technology that offers multi-gigabit-per-second data rates with a higher capacity and lower latency than today's wireless systems, was recently announced by the wireless communications industry. Future phones and base stations will need multimode antenna technology that is both energy-efficient and can function in the millimeter wave band in conjunction with legacy 4G and sub-6 GHz 5G. Antennas should be small in size, but they must meet technical criteria, such as a greater power, wider bandwidth, higher gain, and insensitivity to human users' hand-held influence. The usage of the millimeter wave band, which will provide a network of tiny cells enabling high-capacity and area-efficient hotspot zones, is critical to 5G. The next 5G system will be a true mobile multimedia communication platform, including not just legacy heterogeneous mobile networks but also sophisticated radio interfaces and the ability to operate at millimeter wave frequencies to make use of the vast amount of available capacity. This will impose stringent design standards that go beyond the most recent 5G rollout in the sub-6GHz range.

This Special Issue aims to shed light on recent breakthroughs in antenna design for these new developing applications, as well as highlight more study possibilities in this fascinating field of communications technology. We encourage scholars and practicing engineers to submit original research papers that address:
