【摘要】：针对可见光通信系统中菲涅尔透镜天线无法兼顾高聚光效率和均匀性的问题,设计了一款复合型菲涅尔透镜。通过采用分区法将透镜分成内环区和外环区,提高了菲涅尔透镜的聚光效率,并结合分布式焦点法对透镜结构进行优化,改善了聚光光斑能量均匀性。仿真结果表明,该复合型菲涅尔透镜实现了高聚光效率下的能量均匀分布,适用于高增益、短焦距和小视场角的可见光通信系统。
[Abstract]:Aiming at the problem that Fresnel lens antenna in visible light communication system can not take into account the high concentration efficiency and uniformity, a composite Fresnel lens is designed. By dividing the lens into inner ring and outer ring, the efficiency of Fresnel lens is improved, and the structure of Fresnel lens is optimized by using the distributed focus method, and the energy uniformity of the focal spot is improved. The simulation results show that the hybrid Fresnel lens can achieve uniform energy distribution at high concentration efficiency, and is suitable for visible light communication systems with high gain, short focal length and small field of view angle.
