This award is funded in whole or in part under the American Rescue Plan Act of 2021 (Public Law 117-2). In modern wireless communications systems, antennas with wide-band and directed gain are in great demand, from creating a high-resolution image to downloading data with fast speed. Moreover, such antennas are attractive to automotive applications and defense applications as well, where high gain and large bandwidth are essential parameters to track objects or vehicles. Microstrip antennas are potential candidates for such applications because they are light weight, low cost and easy to integrate. However, their narrow impedance bandwidth and low gain are the critical issues that hinder them from replacing conventional bulky antennas such as horns, etc. Another challenge in microstrip antenna design is that they are computationally extensive and need many optimizations/runs. This research will not only advance the research of microstrip antennas but also act as a seed or pilot project for antenna research at TCNJ (The College of New Jersey) that can excite future multidisciplinary projects and collaborations. As antenna development under this project encompasses many industries from biomedical to defense and communications, it would be a perfect vehicle to excite students’ interest (particularly minority and women) in STEM education and improve their understanding of physical science and mathematical concepts. The project will support PI’s efforts to hire more undergraduate students in the newly developed lab and give them exposure and hands-on experience in antenna design and development.This project aims to develop innovative design solutions to address the computation cost and optimum design’s tradeoff between the microstrip antenna’s current technologies and future needs. This proposal will provide the optimal design solutions for antennas using surface current optimization. These design solutions will be concise, less computationally expensive, and straightforward. In this project, certain critical parameters of the microstrip antenna will be optimized or controlled using surface currents. The focus of this research will be on the following three critical design parameters (i) bandwidth (ii) gain/ radiation characteristics (iii) size of antennas. The analysis and optimization of surface currents make antenna structure easy to understand and comprehend because it gives physical insight into the antenna’s structure. As a result, the analysis and optimal design of the antenna may not need many optimization cycles. Successful completion of the project will improve and simplify design procedures for antenna designers. In the long run, the anticipated technology will develop more useful and concise procedures for designing optimum, low-cost, miniaturized antennas.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.

该奖项的全部或部分资金来源于《2021 年美国救援计划法案》（公法 117-2）。在现代无线通信系统中，由于创建高分辨率，因此对具有宽带和定向增益的天线有很大的需求。此外，这种天线对汽车应用和国防应用也很有吸引力，其中高增益和大带宽是跟踪物体或车辆的基本参数，因为它们很轻，因此它们是此类应用的潜在候选者。然而，它们的阻抗带宽窄和增益低是阻碍它们取代喇叭等传统笨重天线的关键问题。微带天线设计的另一个挑战是它们的计算量大且需要大量计算。这项研究不仅将推进微带天线的研究，而且还将作为 TCNJ（新泽西学院）天线研究的种子或试点项目，可以激发未来的多学科项目和合作。该项目涵盖从生物医学到国防和通信等多个行业，它将成为激发学生（特别是少数族裔和女性）对 STEM 教育的兴趣并提高他们对物理科学和数学概念的理解的完美工具。该项目将支持 PI 的努力：在新开发的实验室中雇用更多本科生，让他们接触天线设计和开发并获得实践经验。该项目旨在开发创新的设计解决方案，以解决微带天线当前技术和未来需求之间的计算成本和最佳设计权衡。该提案将为使用表面电流优化的天线提供最佳设计解决方案，这些设计解决方案将简洁、计算成本较低且简单。在该项目中，将使用表面电流焦点来优化或控制微带天线的某些关键参数。这项研究的重点是以下三个关键设计参数（i）带宽（ii）增益/辐射特性（iii）天线尺寸。表面电流的分析和优化使天线结构易于理解和理解，因为它提供了物理洞察力。进入天线的结构。因此，天线的分析和优化设计可能不需要很多优化周期，该项目的成功完成将改善和简化天线设计人员的设计程序，从长远来看，预期的技术将开发出更有用和简洁的设计程序。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
