| Abstract | Summary form only given. Artificial dielectrics (ADs) are composed of periodic electrically small metallic structures embedded in a host material in order to increase its equivalent relative permittivity. ADs have been extensively studied and used for decades for radar development. Recently, there is an renewed interest in planar ADs, driven by the ever increasing demand for high efficiency silicon integrated antennas (K. Takahagi and E. Sano, IEEE Trans. Antennas Propag., 59-10, 2011). In integrated technology, artificial dielectric layers (ADLs) can be realized by multiple layers of patches with small electrical dimensions. The sub-wavelength sizes of the patches ensure keeping the ohmic losses very low, since no resonant currents are supported. These structures have been shown to enhance the front-to-back ratio and the gain of planar antennas, without supporting surface waves (W. H. Syed and A. Neto, IEEE Trans. Antennas Propag., 61-11, 2013).In this contribution, we present the design and experimental results of a 300 GHz ADL-loaded antenna prototype. The radiator consists of a double slot, fed by a co-planar waveguide and loaded with an AD slab to increase the forward radiation and the gain. The antenna and ADL are shown in Fig. 1(a). The ADL is constituted by 7 layers of periodic patches with 5 m inter-layer distance. An in house silicon based integrated circuit process has been used to realize the prototype. The simulated and measured reflection coefficients are shown in Fig. 1(b). The measurement of the antenna radiation pattern are under progress and will be presented at the time of the conference. |

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.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
