| Abstract | A novel aperture-coupled circularly polarized metallic patch antenna for UHF RFID reader is proposed. In the particular configuration studied, a square patch is placed above a common plane and is fed by means of an aperture-coupled feed network, which adopts sequential rotation technique. The aperture-coupled configuration and multilayer dielectric substrates have the advantage of miniaturizing the antenna's size and enhancing the antenna bandwidth. By means of electromagnetic simulation, the impedance bandwidth and 3 dB axial-ratio bandwidth of the circularly polarized patch antenna presented achieve 58 MHz and more than 1%, respectively. Peak antenna gain across the overall operating band is designed to be 6 dB. Because of taking factors such as cost and weight into account by the selection of dielectric substrates, it's very easy to get the low-cost and light-weight antenna. |

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.
