| Abstract | The potential advantages of using hexagonal-shaped unit-cell metallizations instead of square-shaped ones to enhance the angular stability of Artificial Magnetic Conductors are studied based on simple patch and loop geometries. For a specific resonance frequency and a given dielectric substrate, it is shown that the angular stability is enhanced when increasing the gap distance g from the metallization to the edge of the unit-cell from a certain value, while maintaining suitable operating bandwidth. This effect is observed for both patch-based and loop-based unit-cells and is even more noticeable for hexagonal-shaped metallization. A simplified equivalent circuit model for the unit-cells under study is used to give an insight on the observed behavior. A prototype of the hexagonal-shaped loop-based unit-cell for g=0.9mm has been fabricated in order to experimentally characterize its angular stability in an anechoic chamber, since it is the most stable of the ones under study. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
