与单天线系统相比，多天线通信系统具有更强的鲁棒性和更大的数据容量。然而，当天线彼此靠近时，这种好处就会降低。该提案的目的是首先利用电磁学，信息论和网络理论的基础物理工具探索紧密耦合天线的行为，其次，开发适合紧凑无线通信平台的新型多天线系统。该研究旨在充分利用紧密耦合天线中存在的多种信息通道。提出了通过被动模态分解网络可以独立利用多模态形式的并行信息通道。因此，可以获得超出常规限制和无线链路容量的增强天线增益。更广泛的影响将在紧凑型无线平台上开发新型多天线无线电系统。它促进了天线、电路设计和无线通信等不同工程研究领域之间的互动。在大学和研究生教育中，通过在这些领域开发新的多学科课程，并通过由这些应用需求驱动的技术创新，可以提高科学和工程的水平。拟议活动中的关键概念和技术突破将使下一代通信或传感器产品成为可能，这些产品将具有高性能，紧凑和负担得起。这些组件和设备将改变人类的生活方式，促进工业制造过程，造福社会经济。拟议的活动还将促进设计更简单、更紧凑和更有效的雷达、军用无线电和传感器系统。因此，它可以为建立强大的国家安全和国防网络提供巨大的好处。

ECCS-0725929Yuanxun Wang, UCLAIntellectual merits A communication system with multiple antennas promises enhanced robustness and increased data capacity in comparison with single antenna systems. However, this benefit degrades when antennas are placed close to each other. The objective of the proposal is to first explore the behavior of closely coupled antennas using tools from the fundamental physics of electromagnetics, information theory and network theory, and secondly, to develop a new class of multi-antenna systems that are appropriate for compact wireless communication platforms. The proposed research is to fully exploit the multiple information channels that exist even in closely coupled antennas. It is proposed that the parallel information channels in the form of multiple modes can be utilized independently through a passive mode decomposition network. Consequentially, enhanced antenna gain beyond conventional limits and wireless link capacity can be obtained. Broader impactsA new class of multiple-antenna radio systems on compact wireless platforms will be developed. It fosters the interactions among different engineering research areas in antennas, circuit design and wireless communications. The state of science and engineering can be advanced through the development of new multi-disciplinary curriculums on those areas in both college and post graduate educations and through the technology innovations driven by the demands of such applications. The key concepts and technological breakthroughs in the proposed activities will enable the next generation of communication or sensor products that will be of high performance, compact and affordable. These components and devices will change human lifestyle and facilitate the industry manufacturing process to benefit the social economy. The proposed activity will also promote simpler, more compact and effective designs of radars, military radios and sensor systems. It can thus provide enormous benefits to establishing strong national security and defense networks.
