可见光通信中光学天线的研究
Research of optical antenna technology in visible light communication
摘要
Abstract
As a new wireless communication technology combined illumination with communication, visible light communication has become attractive recently.Optical antenna plays a significant role in visible light communication system for it can optimize the light intensity distribution,enhance the received optical power,and improve the signal to noise ratio of the system.Research on optical antenna is mainly focused on the transmitting antenna or the receiv-ing antenna. Transmitting antenna is usually combined with LED optical design, which can be divided into collimation type,uniform illumination type,and focus type according to the light intensity distribution.Receiving an-tenna uses composite parabolic concentrator ( CPC) ,Fresnel lens or other optical components as the optical receiv-ing front end to enhance the received optical power. In this paper, the research of optical antenna at home and abroad is introduced.The optical performance of the optical antenna is evaluated and compared,and finally the de-velopment trend of the optical antenna is forecasted.关键词
