| Abstract | This paper describes the design of mushroom EBG (Electromagnetic Band Gap) structure within slit defected on power supply plane in order to control PI (power integrity) for realizing high-density multi-stacked printed circuit board. Generally, EBG structure is not suitable to block the low frequency noise around 1GHz in the printed circuit board, because EBG structure requires large area to cutoff low frequency noise. In this paper, new type of mushroom EBG structure, which has slit defect on power supply plane, to increase inductance for EBG function was proposed. By applying the new mushroom EBG structure of small patch size 10mm × 10mm × 3 pieces in the 0.9 mm thickness printed circuit board, we realized -40dB isolation at stop band frequency 0.94GHz~1.25GHz. Consequentially, the multi-stacked printed circuit board thickness could be reduced to 81% of using conventional mushroom EBG structure. |

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.
