Abstract | In order to prevent interference with some selected narrowband communication channels, UWB filters with rejections at these bands are preferred or sometimes necessary for some UWB systems. In this paper, for the first time, a technique for generating rejection notches in the miniaturized UWB filters employing the E-shape microstrip structure is presented. It is shown the attenuated bands can be achieved by capacitively coupling grounded quarter wavelength (λ/4) stub or E-shape microstrip structures to the main filter structure. The performances of a second-order filter with a single rejection notch and a third-order filter with one and two rejection notches are evaluated using an accurate equivalent circuit model as well as by simulation and measurement. The dimensions of the third-order filter are about 4 mm × 4.2 mm × 0.4 mm excluding the feeding ports. |

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.
