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

在2006和2007两个财政年度，日本科学促进会（JSPS）的科学研究资助和新能源技术开发组织（NEDO）的配套基金方法下的大学研发成果实际应用资助都得到了采用。那么，我们已经完成了在这两个项目之间划清界限的工作。也就是说，JSPS的研究目标是“为大学生实验项目开发基于x波段六端口的VNA原型”，因为它的项目名称是“用于两端口设备测量的便携式x波段六端口矢量网络分析仪的试验制造”。作为优异的成果，我们发表了十一篇论文，包括国际会议论文集，如：“UWB无线系统的带通滤波器的设计；第十届澳大利亚天线学术研讨会，2007年2月，“粒子群优化在UWB带通滤波器设计中的应用”；IEEE国际研讨会，2007年6月，“宽动态范围的杂散发射测量；第十一届微波与光学技术国际学术研讨会，2007年12月”等。另一方面，NEDO的研发目标是“使用我们的六端口测量技术在高频工业的各个领域广泛应用”。“有了这两个结果，我们现在正在研究作为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.
