| Abstract | In this paper, a new design method of the dual-band bandpass filter which consists of Stepped-Impedance Resonators (SIRs), Open-Loop Ring Resonators (OLRRs) and feed lines with SIRs is proposed. The length of feed line with SIR electrically becomes half wavelength at the first resonance frequency and one wavelength at the second resonance frequency, and so the size of filter may be reduced. And to improve the attenuation at the stopband and minimize the coupling between the first band resonator and the second band resonator, the second harmonic frequency of the SIR constituting the first band resonator may be moved out of operating frequency range. The proposed design method may be confirmed to be useful from measured results for dual-band bandpass filter operated at 2.45 GHz and 5.8 GHz. |

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.
