IEEE 802.11.ad标准可支持新一代WLAN移动产品在2.4/5.2/60GHz三频段之间的随意切换，从而获得无间断无缝隙的无线网络通信。为满足消费者对产品多功能且超轻超薄的需求，小型2.4/5.2/60GHz三频集成天线是其必不可缺的关键部件。针对三频集成天线设计与实现可能遇到的理论与技术问题，本项目主要研究内容包括：易于集成设计的2.4/5.2GHz双频天线的小型化技术；提高60GHz网格阵列天线增益的新技术和实现圆极化的方法；和易于AiP设计方案的集成天线布局与构造，并最终实现小型线极化和圆极化三频集成天线。考虑射频系统多采用差分设计，为提高系统效率减小巴伦损耗，本项目将在前三项内容基础上研究小型差分三频集成天线。本项目的研究能为WALN移动通信系统的发展提供理论指导和技术储备，有利于推动新一代WLAN产品的应用和产业发展。

The IEEE 802.11.ad standard has been approved to support wireless communication over the following tri-band: 2.4, 5.2, and 60 GHz. It will make the future WLAN radio devices to switch among these three bands freely and seamlessly. To meet comsumers' demands on versatile and ultra-slim portable products, the 2.4/5.2/60GHz tri-band integrated antenna is the key component. For the theoretical and technical problems that may be encountered in the antenna design, the project intends to carry out researches on the following aspects: compact 2.4/5.2GHz dual-band antennas miniaturization technologies for easily integating, 60GHz grid array technologies to improve the antenna gain and achieve circular polarization, the layout of tri-band integrated antennas for the antenna-in-package solution, and finally to achieve 2.4/5.2/60GHz tri-band integrated linear and circular polarization antennas. Considering differential RF system designs, in order to improve the system efficiency and reduce the balun loss, this project will study compact differential tri-band integared antennas on the basis of the first three contents. It will provide the theoretical guidance and technical reserves for the development of WLAN systems, and will promote the new generation of WLAN product application and industrial development.
