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日益广泛。工作在毫米波频段提供了非常大的带宽，可以很容易地解决低频微波频段拥挤的频谱问题。然而，毫米波系统存在多径衰落、干扰和传播路径损耗等问题，导致其传输质量、覆盖范围和容量等性能受到限制。为了解决这些问题，我们在本项目中提出开发基于有源频率面（FSS）结构的动态辐射方向图的新型毫米波可重构天线。使用这种方法，我们的目标是提供一种可靠和紧凑的替代现有天线技术，以改善传输质量并增加在60 GHz左右的V波段工作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.
