Abstract
With the rapid development of modern communication technology, the antenna, as the core component in the wireless communication system, plays a vital role in the signal transmission and reception. This study aims to explore the key issues of antenna design and performance optimization in communication engineering to meet the increasing demand of high frequency band, high bandwidth and high performance. By combining electromagnetic field theory with advanced numerical simulation methods, this paper proposes an antenna design fr amework based on a multi-ob jective optimization algorithm, which can effectively balance the key parameters such as antenna gain, bandwidth, directionality and size. New composite materials were introduced to reduce loss and improve radiation efficiency, and their application potential in millimeter-wave frequency band was verified by experiments. The results show that the designed antenna shows excellent performance in 5G and future 6G communication scenarios, especially in terms of stability and adaptability in complex electromagnetic environments.
