英文摘要： 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.
