ECCS - 1342367 Ruyle, Jessica University of Oklahoma Norman CampusBRIGE: Investigation of Improved Antenna Reconfiguration MechanismsABSTRACTIntellectual Merit: This BRIGE proposal describes a plan to develop mechanisms for slot antennas that will enable numerous unique reconfigurable antenna designs for the next generation of wireless technology. The project represents the first step of a long-term goal to build a diverse team of researchers at the University of Oklahoma (OU) investigating novel antenna architectures that address a national need to solve the spectrum crisis. The first step in designing practical and efficient, reconfigurable slot antennas is development of the loading mechanism that electrically alters a property of the antenna. Slot antennas have many desirable properties such as omnidirectional radiation and relative placement insensitivity. However, reconfigurable antennas are challenging with slotline due to the presence of only one ground plane, which makes the required bias networks problematic and detrimental to the antenna's performance. The proposed work will develop easily-biased and efficient loading mechanisms for slot antennas that will enable many reconfigurable antenna designs and lead to more practical designs to be implemented in systems.Broader Impacts: The proposed work will advance many types of reconfigurable antennas, which have the potential to operate at a range of frequencies, change the main beam to receive/transmit from a different direction, and/or adapt to changes in operating conditions. This will enable truly cognitive radio/radar that can find and operate in unused spectrum - eliminating the requirement for strictly assigned spectrum use. Transmission line models will be developed for all investigated structures allowing the structures to be broadly applicable and transferable for use as loading mechanisms for many different reconfigurable antenna designs. Accurate models for these structures will have far-reaching effects beyond the proposed work since with these models the fundamental structure behavior can be more easily understood. In addition to the broad impact upon future wireless systems, the proposed work will enhance the retention and recruitment of women in Electrical and Computer Engineering (ECE). The PI is the founder and faculty advisor of Women in ECE (WECE) at OU. The proposed work will expand previously initiated events and implement a laboratory workshop with WECE. Students who complete the workshop will be recruited to participate in undergraduate research with the PI. Additionally, the PI will begin tracking all students in ECE through a detailed data set for each cohort of students for the next five years to determine critical points for intervention methods to improve retention.

ECCS - 1342367 Ruyle，Jessica俄克拉荷马州大学Norman CampusBRIGE：改进的天线重构机制的研究摘要知识产权：BRIGE的建议描述了一个计划，以开发缝隙天线的机制，这将使许多独特的可重构天线设计的下一代无线技术。该项目代表了长期目标的第一步，即在俄克拉荷马州大学（University of Oklahoma）建立一支多元化的研究团队，研究新型天线架构，以解决国家解决频谱危机的需求。设计实用有效的可重构缝隙天线的第一步是开发加载机制，该加载机制可以电气地改变天线的特性。缝隙天线具有全向辐射和相对位置不敏感等特性。然而，可重构天线是具有挑战性的槽线由于只有一个接地平面的存在，这使得所需的偏置网络的问题和有害的天线的性能。拟议的工作将为缝隙天线开发易于偏置和有效的加载机制，这将使许多可重构天线设计成为可能，并导致更实用的设计在系统中实现。所提出的工作将推进许多类型的可重构天线，这些天线具有在一定频率范围内工作的潜力，改变主波束以从不同方向接收/发送，和/或适应操作条件的变化。这将使真正的认知无线电/雷达能够在未使用的频谱中发现和运行-消除对严格分配频谱使用的要求。传输线模型将被开发为所有调查的结构，使结构是广泛适用的和可转让的使用作为许多不同的可重构天线设计的加载机制。这些结构的精确模型将产生深远的影响，超出了拟议的工作，因为这些模型的基本结构行为可以更容易地理解。除了对未来无线系统的广泛影响外，拟议的工作还将加强电气和计算机工程（欧洲经委会）中妇女的保留和征聘。PI是欧洲经委会妇女（WECE）的创始人和教员顾问。拟议的工作将扩大以前发起的活动，并与欧洲经委会一起举办一个实验室讲习班。完成研讨会的学生将被招募参加PI的本科研究。 此外，PI将开始跟踪所有学生在幼儿教育通过一个详细的数据集为每个学生在未来五年，以确定关键点的干预方法，以提高保留。
