| Abstract | Rigorous spectral-domain analysis of uniform slotline has shown that the longitudinal electric field can be significant in electrically wide slots and in slots on electrically thick substrates. The present study includes the effects of both longitudinal and transverse electric slot fields and incorporates the proper edge conditions for each component of the field at the edges of the slot and the short-circuited end of the slot. Like the open-circuit discontinuity in microstrip, the short-circuit slotline discontinuity is nonideal because it radiates power into surface and space waves. The nonideal aspects of open-circuit microstrip and short-circuit slotline discontinuities are compared. The magnitude and phase of the reflection coefficient versus frequency are plotted for a shorted slotline on a substrate with a relative dielectric constant of 20.0 and thickness of 3.175 mm for various slot widths. It can be seen that, as with the microstrip open-circuit discontinuity, the radiation loss becomes very large near the cutoff frequency of the second surface wave mode.< |

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.
