Abstract:

Considering the non-ideal factors of the actual impedance matching network, and in order to achieve low Standing Wave Ratio (SWR) and high transmission efficiency, an impedance matching method for radio frequency antenna was proposed based on Dual-aimed Chaotic Particle Swarm Optimization (DCPSO) algorithm. The experimental results of single-frequency impedance matching obtained by DCPSO proves that SWR and output power performance are improved compared with Particle Swarm Optimization (PSO). Combined with real frequency method, broadband impedance matching experiments were done with working band of 2G, 3G and 4G mobile technologies, results show that the entire band can get good results with impedance matching transmission efficiency.

摘要:

考虑实际阻抗匹配网络的非理想因素,为兼顾射频天线的驻波比小和功率传输效率高的目标,提出一种基于混沌粒子群算法的射频天线阻抗匹配方法,利用双目标优化混沌粒子群算法实现单频率点的阻抗匹配,实验结果证明实现的驻波比与输出功率性能都有所提高。另外结合实频法进行宽带阻抗匹配,选取2G,3G与4G移动通信技术的工作频段进行实验,结果表明在整个工作频段都能实现良好的阻抗匹配效果与传输效率。
