Antennas are key components of ubiquitous wireless communication, radar, and navigation systems that affect widespread societal needs, such as aerospace systems, healthcare, and space exploration. Most of the antennas used in a variety of applications including cellular phones to unmanned aircraft systems (UAS) are based on flat planar structures or wire geometries that are developed using traditional manufacturing technique. This approach does not allow designers the opportunity to fully leverage the geometry, space, and materials available to design better performing antennas. The focus of this CARRER development project is on an emerging antenna fabrication technique that combines additive manufacturing (AM) and pulsed laser machining that has the potentials to fundamentally alter the existing state of the art. The proposed research will allow engineers to implement smaller, efficient, lighter, and reconfigurable antenna embodiments in three-dimensions (3D) for future applications with increasing complexity. The research proposed in this project is fully integrated with an education and outreach plan. The educational plan will impact the next generation of professionals by exposing high school students to hands-on activities and videos to explain basic antenna engineering concepts. The videos will be made by accomplished engineers in the engineering field to have a strong role-model-based motivational component to stimulate them to pursue STEM careers. An advanced cellular phone-based teaching tool that allows engineering undergraduate students to visualize complex 3D concepts in electromagnetics and antenna engineering is also proposed. The overall goal of this project is to pursue the discovery of the next generation of antennas with reconfigurable performance while conserving size, weight and cost. Research initiatives include: (a) the investigation of novel additive manufacturing processes for the fabrication of conformal 3D multiple curved antennas based on laser-enhanced direct print AM (LE-DPAM) with femtosecond laser machining and 5-axis kinematics, (b) the study of bio-inspired 3D superior antenna geometries that are not possible to manufacture using traditional methods but are conceivable using LE-DPAM, (c) the development of design methods based on a novel 3D to 2D conformal mapping technique, (d) the study of embedded material- and IC-based reconfigurability mechanisms including the use of electrically tunable inks that can be deposited on conformal surfaces, as well as IC-based switches for reconfiguration of antenna feeds and loads, and (e) the investigation of the structure-property relationships of commercially available and custom-formulated inks that provide excellent electromagnetic performance while addressing the needs for aviation and space environments.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.

天线是无处不在的无线通信、雷达和导航系统的关键组件，影响着广泛的社会需求，如航空航天系统、医疗保健和太空探索。在包括蜂窝电话到无人驾驶飞机系统（UAS）的各种应用中使用的大多数天线基于使用传统制造技术开发的平坦平面结构或导线几何形状。这种方法不允许设计人员有机会充分利用可用的几何形状、空间和材料来设计性能更好的天线。该CARRER开发项目的重点是一种新兴的天线制造技术，该技术结合了增材制造（AM）和脉冲激光加工，有可能从根本上改变现有的最新技术水平。拟议的研究将使工程师能够在三维（3D）中实现更小，更高效，更轻和可重新配置的天线实施例，以满足未来复杂性不断增加的应用。 该项目中提议的研究与教育和推广计划完全结合。该教育计划将通过让高中生参与实践活动和视频来解释基本的天线工程概念，从而影响下一代专业人士。这些视频将由工程领域有成就的工程师制作，具有强大的基于角色模型的激励成分，以激励他们追求STEM职业。还提出了一种先进的基于蜂窝电话的教学工具，使工程本科生在电磁学和天线工程中的复杂的3D概念可视化。该项目的总体目标是寻求发现具有可重构性能的下一代天线，同时节省尺寸，重量和成本。研究活动包括：（a）研究用于基于具有飞秒激光加工和5轴运动学的激光增强直接打印AM（LE-DPAM）制造共形3D多弯曲天线的新型增材制造工艺，（B）研究生物启发3D上级天线几何形状，其不可能使用传统方法制造，但可以使用LE-DPAM来想象，（d）研究嵌入式材料和基于IC的可重构性机制，包括使用可沉积在共形表面上的电可调谐墨水，以及用于天线馈电和负载重构的基于IC的开关，以及（e）对商用和定制配方油墨的结构-性能关系的研究，这些油墨提供优异的电磁性能，同时满足航空和航天环境的需求。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
