BRIGE: Investigation of Improved Antenna Reconfiguration Mechanisms

Ruyle, Jessica，俄克拉何马大学诺曼校区bridge：改进天线重构机制的研究摘要知识优点：该bridge提案描述了一个开发槽天线机制的计划，该机制将为下一代无线技术实现许多独特的可重构天线设计。该项目代表了俄克拉何马大学（OU）长期目标的第一步，该目标是建立一个多元化的研究团队，研究解决国家需要的新型天线架构，以解决频谱危机。设计实用、高效、可重构的槽型天线的第一步是开发可用电改变天线特性的加载机构。槽天线具有全向辐射和相对放置不敏感等优点。然而，由于只存在一个地平面，可重构天线在槽线上具有挑战性，这使得所需的偏置网络存在问题，并且对天线的性能有害。提出的工作将为槽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。更广泛的影响：拟议的工作将推进许多类型的可重构天线，这些天线有可能在一定频率范围内工作，改变主波束以从不同方向接收/发射，和/或适应操作条件的变化。这将使真正的认知无线电/雷达能够发现并在未使用的频谱中运行，从而消除了严格分配频谱使用的要求。将为所有研究结构开发传输线模型，使结构广泛适用，并可作为许多不同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，因为这些模型可以更容易地理解基本结构行为。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）部门对妇女的保留和征聘。PI是开放大学欧洲经委会妇女（WECE）的创始人和教师顾问。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将开始通过未来五年每组学生的详细数据集跟踪ECE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.
