The aimed project addresses the challenges faced, when exhibiting high data rate mobile wireless communication links in the millimeter-wave band. The increase in free-space path loss and oxygen absorption in combination with a large bandwidth leads to a very stringent link budget. To achieve a reasonable high signal to noise ratio, the use of high gain antenna systems is inevitable. However, highly directive communication links necessitate for the ability to dynamically adjust the orientation of the antennas main beam. Thereby, the trend is towards replacing any mechanical component by electronic steering mechanisms. Mechanically steered antennas are in general bulky, heavy, maintenance intensive and hence costly, making them unattractive for mobile applications and consumer products. However, the implementation of a phased array system comprising NxM array elements with the same amount of independent RF channels in order to apply the necessary phase and amplitude weighting in the baseband is as well complex, bulky and cost intensive. A more promising approach is to perform the phase weighting in the RF domain utilizing passive phase shifters, which reduces the amount of independent RF channels. This project focuses on the innovative application of liquid crystal as tunable material together with active components for the realization of hybrid array antenna systems. Here, one challenge lies in the requirements placed on the phase shifting component. Due to their assignment to each array element, they have to be that compact to fit behind one antenna. At the same time, they are required to be compact, flat and low-loss to meet the overall requirements for mobile applications. Further, the phase shift introduced has to be large enough to cover the angular steering range for the specific application. Although the low-loss properties of LC, it is still difficult to meet the above mentioned criteria altogether, especially concerning the losses. Therefore, this project aims for a new approach by combining, for the first time, active components and tunable passive LC phase shifters to diminish the strong requirements placed on the phase shifters. Further, the integration of variable gain amplifiers in such a system enables the possibility for full beam synthesis (i.e. phase and amplitude weighting).To accomplish the above mentioned goals, a systematic technique to design hybrid/active phased arrays will be developed. The passive phase shifters will be realized in innovative and promising low-loss LC technology. Transceiver ICs will be integrated and packaged into the antenna panel in order to increase the system performance in terms of SNR, size and power consumption. The challenges will be, to incorporate this concept into the design procedure as well as the integration of active with LC based passive components.

目的项目在显示高数据速率移动无线通信链接时应对所面临的挑战。自由空间路径损失和氧气吸收的增加与大型带宽相结合导致非常严格的链路预算。为了达到合理的高信号与噪声比，不可避免地使用高增益天线系统。但是，高指令的通信链接需要动态调整天线主梁方向的能力。因此，趋势是通过电子转向机制代替任何机械组件。机械转导的天线通常是笨重，沉重，维护密集型，因此成本高昂，使它们对移动应用程序和消费产品没有吸引力。但是，实施一个分阶段阵列系统，该系统包括具有相同数量的独立RF通道的NXM阵列元素，以便在基带中应用必要的阶段和振幅加权，这也是复杂，笨重和成本密集的。一种更有希望的方法是利用被动相变的RF域中执行相位加权，从而减少独立的RF通道的量。该项目的重点是将液晶作为可调材料的创新应用以及活性组件，用于实现混合阵列天线系统。在这里，一个挑战在于对相位转换组件的要求。由于它们对每个阵列元件的分配，它们必须是紧凑的才能适合一个天线后面。同时，它们必须紧凑，平坦和低损坏，以满足移动应用程序的总体要求。此外，引入的相移必须足够大，以覆盖特定应用的角度转向范围。尽管LC的低损失特性仍然很难完全满足上述标准，尤其是关于损失的标准。因此，该项目的目的是通过首次将主动组件和可调的被动LC相位变速器相结合，以减少相位变速器上的强大要求。此外，在此系统中，可变增益放大器的集成可以使全光束合成（即相位和振幅权重）。要实现上述目标，将开发一种系统设计混合/主动阶段阵列的系统技术。被动相位变速器将在创新和有希望的低损失LC技术中实现。收发器IC将集成并包装到天线面板中，以提高SNR，大小和功耗的系统性能。挑战将是将此概念纳入设计程序，以及与基于LC的被动组件的集成在一起。
