项目摘要

In the last decade, demand has been increasing for higher data rates in wireless access systems to meet the needs for increasing capacity. This demand on high bandwidth leads inevitably to increasing operating frequencies of the systems up to the mm-wave range, where still large frequency resources are available, in particular beyond 100 GHz. However, power link budget considerations and the reduction of interference and multipath effects require high-gain narrow-beam antennas. These antennas have to be precisely oriented to avoid alignment losses, which is not an easy task. Moreover, an increasing demand is going towards mobile communication systems, where electronic beam-steering capabilities would increase the system´s performance dramatically compared to heavy and bulky mechanical systems, causing additionally high maintenance. However, this is a considerable hardware and implementation challenge, due to the lack of suitable low-cost, reliable technologies for reconfigurable mm-wave components and particular constraints in terms of systems' beam-steering rate and power consumption as well as form factor, taking compactness and flatness into account.In this context, the project aims (1) for a new technology, which meets all the system requirements at the same time, and (2) to build up an innovative development platform for further system realizations. For this approach, two recently and independently developed technologies will be merged in order to achieve higher functionality and performance with respect to the individual ones: (1) the microwave liquid crystal (LC) technology from TU Darmstadt, Germany, and (2) the metallic nanowire-filled membrane (NaM) technology from UJF in France and USP in Brazil. Small, low-profile and high-efficiency passive circuits will be possible, using the slow-wave concept. Tunable circuits such as phase shifters and switches based on the microwave liquid crystal technology will benefit from a slow-wave concept combined with the nanowire-filled membrane technology. This allows miniaturization, to fit the phase shifters into a single antenna element size of about a half-wavelength squared, and fast response times with low-profile structures, which are the major limitations of the state-of-the-art microwave liquid crystal technology and components.For a proof-of-concept and feasibility studies, a system-level demonstrator, a beam-steering antenna system in the D-band around 140 GHz will be built and tested in two use cases, in order to leverage the developments carried out. It will consist of a small-footprint antenna array and a complex feeding network, including Butler matrix and switching elements as well as phase shifters. This beam-steering antenna system is based on a new concept, using a hybrid phase-shifting approach, combining the discrete phase shift from a Butler matrix with the continuous phase shift from liquid crystal phase shifters to achieve a large scanning range with low losses at 140 GHz.

在过去的十年中，对无线接入系统中更高的数据速率的需求一直在增加，以满足不断增加的容量的需求。这种对高带宽的需求不可避免地导致系统的操作频率增加到毫米波范围，其中仍然有较大的频率资源可用，特别是超过100 GHz。然而，考虑到功率链路预算以及减少干扰和多径影响，需要高增益窄波束天线。这些天线必须精确定向，以避免对准损失，这并不是一项容易的任务。此外，越来越多的需求流向移动通信系统，与笨重和笨重的机械系统相比，电子波束控制功能将显著提高系统的性能，导致额外的高维护。然而，这是一个相当大的硬件和实现挑战，原因是缺乏合适的低成本、可靠的可重构毫米波组件技术，以及考虑到紧凑性和平坦性的系统波导率和功耗以及形状因数方面的特殊限制。在此背景下，该项目的目标是(1)开发一种同时满足所有系统要求的新技术，(2)为进一步的系统实现建立一个创新的开发平台。在这种方法中，将合并最近独立开发的两项技术，以实现相对于单独技术更高的功能和性能：(1)德国达姆施塔特工业大学的微波液晶(LC)技术，以及(2)法国UJF和巴西USP的金属纳米线填充膜(NAM)技术。使用慢波概念，小型、低轮廓和高效率的无源电路将成为可能。基于微波液晶技术的移相器和开关等可调电路将受益于慢波概念与纳米线填充膜技术的结合。这使得移相器可以小型化，可以将移相器安装到大约半个波长平方的单个天线单元中，并且响应速度快，具有低轮廓结构，这是最先进的微波液晶技术和组件的主要限制。为了概念验证和可行性研究，将建造一个系统级演示器，即D波段约140 GHz的波束控制天线系统，并在两个使用案例中进行测试，以利用所进行的开发。它将由一个占地面积小的天线阵列和一个复杂的馈电网络组成，包括Butler矩阵和开关元件以及移相器。这种波束控制天线系统基于一种新的概念，使用混合相移方法，将Butler矩阵的离散相移和液晶移相器的连续相移相结合，以实现140 GHz的大扫描范围和低损耗。
