| Abstract | Band-pass filters with low insertion loss and high frequency selectivity are widely used in the modern electric device and communication systems. With the requirement of the electrical system miniaturization, embedded filter was proposed because of its light weight and excellent performance. In this paper, a fully embedded VHF band-pass filter with bandwidth from 280 MHz to 400 MHz is designed and fabricated based on the BaTiO3-epoxy composite film. The filter is composed of a power plane with cross coupled microstrips and a double helical ground structure (DGS). The size of the band-pass filter is 5mm× 5 mm. It was embedded in a multi-layered FR-4 packaging substrate through the PCB manufacturing process. The measured results of insertion loss and return loss are similar to the simulated results. The measured results shows that the insertion loss is no more than 3.8 dB in pass-band and over 10 dB suppression is obtained at above 1.2 GHz, which is important for the practical application in communication. The embedded band-pass filter using BaTiO3-polymer film as a substrate is a new way for electronic system miniaturization. |

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.
