With 3 million dollars in grant funding from the National Institute for Standards and Technology for the proposal entitled “十大菠菜台子 Vehicular Wireless Communications System Testing and Standards Facility,” 十大菠菜台子’s School of 工程与计算机科学 will acquire an indoor Automotive Antenna Measurement System (AAMS) capable of performing both on-vehicle full-scale  three-dimensional antenna pattern measurements (APM) and over-the-air testing (OTA) of wireless communication systems. 

丹尼尔·阿洛伊博士.D., 电子与计算机工程教授, SECS研究主任, 也是这个奖项的首席研究员, believes that this funding will make a significant regional and national impact. 作为唯一独立的, 多用户, 在美国拥有这种能力的公用设备, AAMS将支持研究, 发展, 培训, and the certification of automotive wireless communication systems.

提高安全性, 车辆乘员的便利和娱乐, the automotive industry is aggressively pursuing wireless technologies. 这, 反过来, creates a critical need for educating the next generation of automotive antenna/wireless communications engineers. 另外, 车载天线测试和无线系统测试, required for the 发展 and adoption of safety-critical wireless technologies, 是一个复杂而昂贵的过程吗. 因此, 一个汽车电磁研究中心, incorporating an independent antenna/wireless communications test capability for both research 和行业, 变得极为重要.

“The acquisition of the AAMS is intended to replace the existing OU antenna testing instrument that has been housed in the Applied EMAG and Wireless Laboratory and successfully operated and maintained for over 15 years. 在此期间, 我们已经建立了一个用户社区, 包括公开大学的研究团队, 其他大学的教员, 和行业, 以及训练有素的学生, supported a variety of outreach and workforce 发展 programs, 并帮助招收新生. 由于无线通信新技术的出现, 目前的文书已不能再支持这些活动,博士说。. Aloi, who will function as a principal investigator and the Director for the AAMS, 在Amanpreet Kaur的支持下, Ph.D.他是电子与计算机工程助理教授.

The AAMS is expected to enable research in antenna design for Global Navigation Satellite Systems (GNSS), Vehicle-to-Everything (V2X), 和蜂窝5G通信. The antenna solutions for these areas are challenging because they cover wide frequency ranges, are co-located under the same radome and have strict size limitation requirements.  Furthermore, the next generation of antenna solutions will come in the form of smart arrays. 这些阵列需要一致性和小型化, while still providing the necessary pattern coverage and resistance to interference and cyber-security risks.

“As the number and complexity of wireless systems are integrated into the automobile, the need for a process to certify AAMSs for the measurement of on-vehicle antenna performance is imperative. The new equipment will be utilized to investigate both measurement error uncertainty bounds and measurement system certification procedures that will serve as the foundation for much needed automotive standards for accurate vehicle-level APMs across AAMSs. 这将优化蜂窝的性能, GNSS and V2X wireless technologies leading to increased automotive safety on the roadways. We will also utilize this equipment for antenna measurement research to introduce new algorithms, 建立测量精度界限, and work with standards committees for range certification standards,博士说。. Aloi.

The AAMS will be located in the School of 工程与计算机科学’s 研究 and Innovation Center - off-campus facility is located two miles from the main campus.

“作为室内消声室, 它不会经历与天气有关的停机时间, 为学生提供更好的学习机会. We expect that the research results generated as a result of the new AAMS will allow our students grow as researchers and share their fundings with industry and scientific community through publications, 演讲, 论文, 和论文,Louay M. Chamra说，工程与计算机科学学院院长.

One of the first research efforts intended for AAMS are to take advantage of the current outdoor spherical near-field range with conductive ground and the new indoor spherical near-field system in a free space environment to do an extensive accuracy analysis between these different facilities between 600 MHz to 6,000兆赫. The aim of this research is to understand the accuracy limitations that come with vehicle-level hemispherical near-field antenna measurements in terms of accuracy and to roll those into range certification procedure recommendations for the automotive community.
