Trial manufacture of a portable X-band six-port based vector network analyzer for two-port device measurement

在2006和2007这两个财政年度，日本科学促进会(JSPS)的科学研究助学金和新能源和技术开发组织(NEDO)的配对基金方法下的大学研发成果实际应用助学金都获得了通过。JSPS的研究目标是“基于X波段六端口的大学生VNA原型的研制”，项目名称是“便携式X波段六端口矢量网络分析仪的试制”。作为优秀的成果，我们发表了包括国际会议论文集在内的11篇论文，包括“UWB无线系统带通滤波器的设计；2007年2月举行的第十届澳大利亚天线研讨会”和“粒子群优化在超宽带带通滤波器设计中的应用；另一方面，NEDO的研发目标是“利用我们的基于六端口的测量技术在高频工业的各个领域中得到广泛的应用”。有了这两个结果，我们现在正在研究作为一种无频率测量技术的替代应用。

During the same two fiscal years, 2006 and 2007, both Grants-in-Aid for Scientific Research from Japan Society for the Promotion of Science (JSPS) and Grant for Practical Application of University R&D Results under the Matching Fund Method form New Energy and Technology Development Organization (NEDO) were adopted. Then, we have done with drawing a sharp line between these two projects.That is JSPS's research target is “Development of a prototype X-band six-port based VNA for universities student experimental program," as its title of project is “Trial manufacture of a portable X-band six-port based vector network analyzer for two-port device measurement."As excellent results, we published eleven papers including proceedings of international conferences, i. e., “Design of Bandpass Filters for UWB Wireless Systems ; Tenth Australian Symposium on Antennas, Feb.2007," and “Application of Particle Swarm Optimization for the Design of UWB Bandpass Filters ; IEEE International Symposium, June 2007," and “Spurious Emission Measurement with Wide Dynamic Range ; 11th International Symposium on Microwave and Optical Technology, Dec. 2007" and so on.On the other hand, NEDO's research and development target is “Wide application in various fields of high frequency industry using our six-port based measurement techniques."With both results, we are now researching in alternative applications as a frequency free measurement techniques.
