This project is constructing an Internet-accessible antenna range in an anechoic chamber that is large enough to characterize the types of antennas that are suitable for personal electronic devices in the frequency bands between 1 and 18 GHz. With this facility and readily available software packages, students can design, simulate, and test antennas. The investigators have students construct their antenna using simple techniques such as elements printed on circuit boards and cutting and assembling metal and dielectric parts with hand tools. In addition, they are making an antenna construction kit available that will allow students at other sites to build simple wire and printed antennas. This web-based facility when coupled with the implementation techniques being developed will allow students across the country to design and test antennas without duplicating this costly facility. Formative and summative assessments, using both quantitative and qualitative methods are being employed to evaluate and improve the effectiveness of the remote user experience and its impact on student learning and interest in electromagnetics. The availability of the facility will be widely advertised through presentation at conferences, lab tours, targeted letters, and a workshop. They also plan to publish the results of their study in engineering education conferences proceedings and in archived journals. The laboratory is being developed in collaboration with San Diego State University, and beta tested at San Diego State, the University of Tennessee, Knoxville, and the University of Washington.

该项目正在电波暗室中构建一个可接入互联网的天线范围，该天线范围足够大，可以表征适合 1 至 18 GHz 频段的个人电子设备的天线类型。 借助该设施和现成的软件包，学生可以设计、模拟和测试天线。 研究人员让学生使用简单的技术构建天线，例如将元件印刷在电路板上以及使用手动工具切割和组装金属和介电部件。 此外，他们还提供天线构建套件，允许其他地点的学生构建简单的电线和印刷天线。 这种基于网络的设施与正在开发的实施技术相结合，将允许全国各地的学生设计和测试天线，而无需重复这种昂贵的设施。 使用定量和定性方法的形成性和总结性评估被用来评估和提高远程用户体验的有效性及其对学生学习和电磁学兴趣的影响。 该设施的可用性将通过会议演示、实验室参观、有针对性的信件和研讨会进行广泛宣传。 他们还计划在工程教育会议记录和存档期刊上发表研究结果。该实验室正在与圣地亚哥州立大学合作开发，并在圣地亚哥州立大学、田纳西大学诺克斯维尔分校和华盛顿大学进行了 beta 测试。
