ECCS-1342367 Ruyle，俄克拉荷马大学诺曼校区Jessica University of Oklahoma Norman Campus BRIGE：改进的天线重新配置机制研究摘要智能优点：这份布里奇提案描述了一项开发缝隙天线机制的计划，该计划将为下一代无线技术实现众多独特的可重新配置天线设计。该项目代表了俄克拉荷马大学(OU)建立一个多样化的研究团队的长期目标的第一步，该团队正在研究新颖的天线架构，以满足全国解决频谱危机的需求。设计实用、高效、可重新配置的缝隙天线的第一步是开发电改变天线特性的加载机构。缝隙天线具有全向辐射、相对位置不灵敏等特性。然而，由于只有一个地平面的存在，可重构天线在缝隙线上是具有挑战性的，这使得所需的偏置网络存在问题，并且不利于天线的性能。这项工作将为缝隙天线开发易于偏置和高效的加载机制，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。广泛影响：拟议工作将促进多种类型的可重构天线的发展，这些天线可能工作在一定频率范围内，改变主波束以从不同方向接收/发送，和/或适应工作条件的变化。这将使真正的认知无线电/雷达能够发现并在未使用的频谱中运行-消除对严格分配频谱使用的要求。将为所有被研究的结构开发传输线模型，使这些结构具有广泛的适用性和可转移性，用于许多不同的可重构天线设计的加载机构。这些结构的精确模型将产生比拟议工作更深远的影响，因为使用这些模型可以更容易地理解结构的基本行为。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)中妇女的留用和征聘。PI是俄亥俄州立大学妇女参与欧洲教育(WECA)的创始人和教职顾问。拟议的工作将扩大以前发起的活动，并与世界欧洲经委会一起举办一次实验室讲习班。完成工作坊的学生将被招募参加PI的本科生研究。此外，PI将开始通过未来五年每个学生队列的详细数据集跟踪幼儿教育的所有学生，以确定干预方法的关键点，以提高保留率。

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.
