摘要

The increasing demand for energy-efficient and high-performance communication systems in next-generation wireless networks such as 5G and 6G has highlighted the need for integrated RF system design strategies. This study aims to develop an integrated RF circuit–antenna co-design framework to improve system efficiency and signal performance in advanced wireless communication systems. The proposed methodology performs simultaneous optimization of RF circuits and antenna structures using a joint modeling approach supported by co-simulation tools such as HFSS and ADS. The framework incorporates energy-efficient power amplifier topologies, including Class-F amplifiers and broadband matching networks, to improve power transfer efficiency while minimizing insertion and parasitic losses. Simulation results demonstrate significant performance improvements compared with conventional independent RF–antenna design methods, including a 100% expansion in operating frequency range, a 41.5% increase in antenna gain, and a 65.9% improvement in overall system efficiency. These results indicate that the proposed RF circuit–antenna co-design strategy enhances signal integrity, reduces energy consumption, and supports emerging applications such as Internet of Things (IoT) and ultra-reliable low-latency communications in future 5G/6G wireless networks.
