SBIR Phase I: Multiple Access Phase Shifter (MAPS)

该小型企业创新研究（SBIR）第一阶段项目旨在展示一种新型多路访问（多频带）移相器（MAPS）概念的可行性，能够同时在多个频带上实现移相器功能。鉴于在日益拥塞的频谱中操作的无线系统的扩散，所提出的MAPS概念解决了对增加频谱效率和重用的需要。虽然当前移相器（PS）的性能令人印象深刻，但它们缺乏同时在多个频带上操作的能力。因此，需要能够实现增强的系统容量的PS，以及新的架构解决方案和概念，以增强频谱效率和重用。该研究有两个主要目标：1）设计和制造一种新型MAPS; 2）通过测量和表征其性能来证明其可行性。该研究解决了与MAPS架构相关的关键技术挑战，以最大限度地提高工作频带及其制造工艺。预期成果包括：1）阐明了MAPS的设计原则; 2）MAPS可行性决定因素的实验实现和测试。该项目的广泛影响/商业潜力将很大。首先，创新将提高对MAPS操作、设计和制造领域的科学和技术理解。其次，这项创新将为航空航天和国防系统、汽车雷达和消费电子等高端系统的新功能铺平道路，特别是这项创新预计将具有数千万美元的潜在商业价值。第三，这项研究将使博士后研究人员能够进一步接受科学培训和指导。特别是，博士后研究人员将从事职业发展活动，如准备和撰写赠款提案，出版物和演示文稿的培训;指导如何提高教学和指导技能;指导如何有效地与来自不同背景和学科领域的研究人员合作;负责任的专业实践培训;和技术转让。该项目将影响许多技术领域和市场部门，如移相器，相控阵天线，无线通信，卫星通信，汽车雷达和纳米制造。

This Small Business Innovation Research (SBIR) Phase I project aims at demonstrating the feasibility of a novel multiple access (multi-band) phase shifter (MAPS) concept, capable of effecting the phase shifter function on multiple frequency bands simultaneously. The proposed MAPS concept addresses the need for increasing spectral efficiency and reuse, given the proliferation of wireless systems operating in an increasingly congested spectrum. While the performance of current phase shifters (PSs) is impressive, they lack the ability to simultaneously operate on multiple frequency bands. There is a need, therefore, for PSs that can enable enhanced system capacity, as well as new architectural solutions and concepts to enhance spectrum efficiency and reuse. The proposed research has two primary objectives: 1) to design and fabricate a novel MAPS; and 2) to demonstrate its feasibility via the measurement and characterization of its performance. The research addresses key technical challenges related to MAPS architecture to maximize operating frequency bands, and to its fabrication process. The anticipated results include: 1) Elucidating the design principles for the MAPS; and 2) The experimental realization and testing of the feasibility-determining elements of the MAPS. The broader impact/commercial potential of this project will be large. In the first place, the innovation will enhance scientific and technological understanding in the areas of MAPS operation, design and fabrication. In the second place, the innovation will pave the way to enabling new capabilities in both high-end systems, such as aerospace and defense systems, automotive radar and consumer electronics, in particular, the innovation is anticipated to have a potential commercial value in the tens of millions of dollars. And in the third place, the research will enable the further scientific training and mentoring of a post-doctoral researcher. In particular, the post-doctoral researcher will be engaged in activities toward career development, such as, training in the preparation and writing grant proposals, publications and presentations; guidance on ways to improve teaching and mentoring skills; guidance on how to effectively collaborate with researchers from diverse backgrounds and disciplinary areas; training in responsible professional practice; and technology transfer. The project will impact a number of technology areas and market sectors, such as, Phase Shifters, Phased-Array Antennas, Wireless Communications, Satellite Communications, Automotive Radar, and nanomanufacturing.
