Abstract

The advent of 5G has presented new challenges and opportunities for smartphone antenna design. With more frequency bands and higher speed requirements, antenna engineers face the task of achieving comprehensive coverage and faster data transmission in smaller smartphone volumes. Additionally, users' demands for network speed and connection quality have increased, necessitating higher-performing and more stable antenna designs. Despite these challenges, antenna engineers can meet market needs through innovation and design optimization. Furthermore, as 5G ushers in a wider range of services, improving the channel capacity of mobile phones is crucial. MIMO technology offers an effective solution by enhancing channel capacity and spectral efficiency. However, integrating numerous antennas into mobile phones restricts space for 5G MIMO arrays, leading to difficulties in achieving isolation and minimizing interference. Moreover, the human body's presence can significantly impact mobile phone antenna performance. Human tissue absorbs and reflects wireless signals, resulting in signal loss and increased interference, ultimately affecting communication quality and user experience. Therefore, studying the influence of the human body on mobile phone antennas can drive better antenna designs and optimize performance, enhancing smartphone communication quality.
