| Abstract | A new type of component, the patch antenna with the relative humidity sensing function using a modified polyimide is proposed for RFID. The proposed structure can be applied for RFID sensor tag as a physically and functionally combined antenna with the RH sensor. For high sensitivity, a polyimide film was synthesized from aromatic monomers where no hydrophobic element is included. The fabricated patch antenna with RH sensing function was characterized in view point of sensitivity. Furthermore, to enhance the resolution of the sensing function, the patch antenna was designed to have a narrower bandwidth by meandering structure. From the measured results, the sensitivity of the proposed structure was -108 kHz/%RH under 25%RH ~90%RH. This means that the proposed component provides the humidity sensing function as well as the radiation. Therefore, it is apparent that the proposed RH sensing antenna using a modified polyimide can be applicable and useful for the implementation of the compact RFID sensor tag |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
