| Abstract | A novel printed reconfigurable square slot antenna with switchable band-notched and multiresonance performances is designed and manufactured. In the proposed structure, in order to generate single band-notched characteristics, a Π-shaped slot is etched on the radiating stub. Furthermore, to achieve a reconfigurable function, a p-i-n diode is utilized across the slot. When this p-i-n diode is biased forwardly, the Π -shaped slot transforms to a pair of C-shaped slots, and also by changing to this new structure, an additional resonance is excited. Additionally, by cutting two modified L-shaped slits with variable dimensions on the microstrip feed line, new additional resonance is excited, and hence wider impedance bandwidth can be produced, especially at the higher band. The designed antenna has a small size of 20 × 20 mm2 while showing the radiation performance in the frequency band of 3.04 to over 11.17 GHz with a switchable band-rejection performance in the frequency band of 5.03-5.94 GHz. Simulated and experimental results obtained for this antenna show that it exhibits good radiation behavior within the ultrawideband (UWB) frequency range and also it has a reconfigurable frequency band-notched function in the range of 5-6 GHz that can eliminate the interference between UWB frequency band and other existing wireless communication systems. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
