　　I. Introduction

　　As an important part of the new generation of information technology, the Internet of Things is profoundly changing people's production and lifestyle. International Data Corporation (IDC) predicts that the number of IoT device connections worldwide will exceed 55 billion by 2025. From smart homes and smart agriculture to industrial IoT and smart cities, the application scenarios of IoT devices are becoming increasingly extensive and complex. These scenarios have put forward higher requirements for network coverage, which not only requires large-area signal coverage, but also requires signal stability, reliability and low latency to meet the data transmission and interaction needs of massive devices. High-gain omnidirectional antennas have become one of the core technologies for solving the problem of IoT network coverage by virtue of their ability to enhance signal radiation in an omnidirectional range, and are of great significance to promoting the development of the IoT industry.

　　II. Analysis of IoT network coverage requirements

　　2.1 Differences in coverage requirements under diverse application scenarios

　　The IoT application scenarios are rich and diverse, and there are significant differences in the requirements for network coverage in different scenarios. In the smart home scenario, the devices are densely distributed and the space is relatively small. The antenna needs to achieve all-round signal coverage in a limited space to ensure stable connection of various smart home appliances, security equipment, etc., while avoiding signal interference and ensuring user privacy and security; the smart agricultural scenario faces the challenge of large-scale and complex terrain. The terrain in farmland, orchards and other areas is undulating and there are many obstacles. The antenna is required to have strong signal penetration and diffraction capabilities to achieve remote and accurate monitoring and control of agricultural equipment; the industrial Internet of Things scenario has extremely high requirements for the stability and reliability of network coverage. There are many devices inside the factory and the electromagnetic environment is complex. The antenna needs to be able to work stably in harsh environments to meet the needs of real-time data transmission and equipment collaborative control in industrial production; smart city construction involves multiple fields such as transportation, energy, and environment, requiring seamless network coverage throughout the city to support efficient operation of applications such as intelligent traffic management, smart grid, and environmental monitoring.

　　2.2 Challenges to coverage capabilities from massive device connections

　　The explosive growth in the number of IoT devices has led to a sharp increase in the data traffic that the network needs to carry. Each device needs to interact with the network for data, which poses a severe challenge to the breadth and depth of network coverage. Traditional network coverage methods are difficult to meet the connection needs of such large-scale devices, and are prone to signal blind spots, network congestion and other problems. At the same time, the communication requirements and power consumption characteristics of different devices are different. For example, low-power wide area network (LPWAN) devices focus on long-distance transmission and low power consumption, while some high-definition video surveillance devices have high requirements for bandwidth and transmission rate. Therefore, the network coverage of the Internet of Things needs to be able to adapt to the diverse needs of devices and provide flexible and efficient coverage solutions.
