Abstract | This Letter presents a low-profile broadband cavity-backed magneto-electric (ME) dipole antenna fed by a substrate integrated waveguide aperture. To reduce the antenna profile, a U-shaped slot is etched on the electric dipole. Compared to the traditional ME dipole antenna whose profile is generally 0.25 λ ε , the thickness of the proposed radiation structure is 0.13 λ ε , where λ ε is the wavelength in the dielectric substrate. A 4 × 4 array antenna with the proposed antenna as its element is then designed, simulated and fabricated. With the return loss is below −10 dB, a 19.1% (30.3–36.7 GHz) impedance bandwidth has been achieved. The radiation pattern of the proposed array antenna is quite stable, and the peak gain varies below 1 dB within the operating band. |

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.
