| Research Abstract |
In this project we proposed the idea of low cost chipless RFID, with long operating range. The construction is simple, of thin metal patches on a metal
base, separated by dielectric. Analyzing the scattering of the sweep signal, the resonant frequency of the patch, and therefore its dimension could be read. The stored information is the dimension of the patch, and reading can be done from a distance using a directed sweep signal. Multiple patches, in close proximity, will increase the stored information in exponential order. The idea, and algorithms of increased sophistication to mitigate the influence of noise have been published in different well-known international conferences as paper, and presented as key-note speeches.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
The target of the project, as written in the application, is complete.All the experiments are done in laboratory environment, with controlled noise sources. Experiments in real factory environment is not done, because multilayer patch or array patch is not ready yet. Even though, a single patch RFID could work perfect, the performance evaluation of multi-patch is necessary for practical application. In addition, for a wider audience, we are now preparing manuscript to publish in a reputed journal.

| Strategy for Future Research Activity |
We need to perform experiments in a real factory environment. The experiments needed to estimate memory storage capability are not complete. As the information storage capacity depends on the noise mitigation, actual capacity of metal-patch RFID in real-situation is yet to be estimated. Noise mitigation using the basic nature of scattering from metallic objects is to be done and compared with the present artificial neural network algorithm to eliminate noise. Comparison of performances between multilayer patch and single layer patch-array is to be experimented.

| Expenditure Plans for the Next FY Research Funding |
提案方式によるRFIDの動作レンジに関する最終成果が成果発表されていない。さらに現在、RFIDの実利用に重要なパラメータとなる情報密度（ユニットあたりの情報量）に関する実験を実施中である。未使用額は、最新成果の次年度での発表費用として使用する。
ここ6～8ヶ月の最新の研究成果の成果発表が完了しておらず、次年度に国際会議での発表とジャーナルへの投稿を予定している。未使用額は、国際会議の登録費用および旅費、ジャーナルの別刷りの費用として使用を予定する。
