Millimeter-wave reconfigurable antennas based on active frequency selective surface structures for wireless communication systems

目前，毫米波无线系统在移动通信、数据传输、高速公路安全、智能交通、民用超宽带雷达等领域的应用层出不穷。工作在毫米波段提供了非常大的带宽，可以很容易地解决低频微波频段的频谱拥挤问题。然而，毫米波系统受到多径衰落、干扰和传播路径损耗的影响，导致传输质量、覆盖范围和容量方面的性能有限。为了解决这些问题，我们在本项目中提出了一种基于有源频率面(FSS)结构的新型毫米波动态辐射方向图可重构天线。使用这种方法，我们的目标是为当前的天线技术提供可靠和紧凑的替代方案，以改善传输质量并增加运行在V波段约60 GHz的毫米波无线通信系统的容量。

Nowadays mm-wave wireless systems are emerging for many applications, such as mobile communications, data transfer, highway safety, intelligent transport, and civilian ultra-wide band radar. Operating at mm-wave band provides a very large bandwidth that can easily resolve the crowded spectrum problem at low frequency microwave bands. However, mm-wave systems suffer from multipath fading, interference and propagation path loss, resulting in limited performances in terms of transmission quality, coverage range and capacity. To address these issues, we propose in this project to develop new class of mm-wave reconfigurable antennas with dynamic radiation pattern based on active frequency surface (FSS) structures. Using this approach, our goal is to offer a reliable and compact alternative to current antenna technologies for improving the transmission quality and increasing the capacity of mm-wave wireless communication systems operating at V- band around 60 GHz.
