Non-Technical Description The existing 4G cellular systems have stretched their capabilities to a limit that they can no longer be extended or incrementally improved to meet the mounting demand for high bandwidth-consumptive mobile services. As the demand for large bandwidth and high data rate for mobile applications is at all-time high, future 5G (5th Generation) mobile terminals must operate at unused millimeter wave (mmWave) bands. It is also expected that existing lower frequency 4G bands will continue to be needed for wide area coverage. In this project, it is proposed to investigate the performance of a new generation of smart dispersed array antenna architecture for future 5G new radios (NRs). The mmWave arrays will be integrated into recently designed 4G/LTE multi-slot antennas for interoperability between cells of 4G networks and future 5G heterogeneous cells. This will provide a unified connectivity platform for existing and emerging connected services. This fellowship will be a unique opportunity for the PI and a graduate student to access state-of-the-art facilities and advanced fabrication equipment. The project outcomes will be utilized to attract members of minority and underrepresented groups to engineering education in the Gulf Coast region. This will also boost the University of South Alabama?s recruiting effort to attract outstanding undergraduate students, and drive up new mobile-based economic development opportunities in the Gulf Coast and in the State of Alabama.Technical DescriptionThe objective of project is to investigate the performance of 3-D dispersed antenna arrays that will be implemented in multiple planes of mobile terminals for future 5G networks, called New Radios (NRs). Orthogonal arrays dispersedly located on various planes of NRs will be studied for Multiple-Input Multiple-Output (MIMO) operation and beam scanning in nearly full spherical region. Miniaturized metasurface-inspired antenna array elements will be based on Dolph-Tschebysheff amplitude weighting, where excitation co-efficient of elements will be related to Tschebysheff polynomials. Smart beamforming algorithm will be developed for a fine scan step with narrow beamwidths in all planes. Two types of array elements will be integrated into a newly designed 4G multi-slot-based MIMO antenna system that will enable NRs to operate in almost all 4G/LTE bands, and multiple mmWave bands, such as 28 GHz and 39 GHz. This will enable NRs with a harmonized connectivity platform for existing and future wireless services. Dispersed arrays, equipped with advanced beamforming and associated feed networks will be developed using 3D printing technology. In this collaborative project, PI Latif and a graduate student will model, simulate and design smart arrays, and implement several prototypes and evaluate the MIMO performance of both LTE and 5G antenna systems. The proposed project will provide the PI a strong platform to develop a thriving research program at the University of South Alabama with a long-lasting impact on his research career in the field of 5G/mmWave technology, that will be benefit other academic institutions, and wireless and auto industries in the State of Alabama.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

非技术描述现有的4G蜂窝系统已将其功能扩展到无法再扩展或逐步改进的限制，以满足对高带宽消费性移动服务的不断增长需求。随着移动应用程序对大型带宽和高数据速率的需求在历史最高时分，未来的5G（第五代）移动终端必须在未使用的毫米波（MMWave）频段下运行。还可以预期，广泛覆盖范围将继续需要现有的低频4G频段。在这个项目中，建议研究新一代的智能分散阵列天线体系结构，以供未来的5G新收音机（NRS）。 MMWave阵列将集成到最近设计的4G/LTE多槽天线中，以在4G网络和未来的5G异质细胞之间互操作。这将为现有和新兴的连接服务提供统一的连接平台。这项奖学金将是PI和研究生获得最先进设施和高级制造设备的独特机会。该项目的成果将被用来吸引少数民族和代表性不足的群体的成员参加墨西哥湾沿岸地区的工程教育。这也将促进阿拉巴马州南部的招聘努力，以吸引杰出的本科生，并为墨西哥湾沿岸和阿拉巴马州的新基于移动的经济发展机会。技术描述项目的目的是调查3-D分散的天线阵列的性能，这些阵列将在未来的5G网络中实现，称为New New New New radios（New New for Mobille）。将研究位于NR的各种平面上的正交阵列，以进行多输入多输出（MIMO）操作，并在几乎完整的球形区域进行横梁扫描。微型跨表面启发的天线阵列元件将基于Dolph-tschebysheff振幅加权，其中激发元件的激发能力将与tschebysheff的多项式有关。将开发智能光束形成算法，以进行精细的扫描步骤，并在所有飞机上都具有狭窄的光束宽度。两种类型的阵列元素将集成到新设计的4G基于多插槽的MIMO天线系统中，该系统将使NRS能够在几乎所有4G/LTE频段中运行，以及多个MMWAVE频段，例如28 GHz和39 GHz。这将启用具有现有和未来无线服务的协调连接平台的NR。配备高级波束形成和相关的进料网络的分散阵列将使用3D打印技术开发。在这个合作项目中，Pi Latif和研究生将建模，模拟和设计智能阵列，并实施多个原型，并评估LTE和5G天线系统的MIMO性能。拟议的项目将为PI提供一个强大的平台，以在南阿拉巴马大学制定蓬勃发展的研究计划，对他在5G/mmwave技术领域的研究生涯产生持久影响，这将使其他学术机构以及阿拉巴马州的无线和汽车行业有益于其他学术机构。 标准。
