| Abstract | In standard antenna array, high grating-lobe caused by large space between elements would degrade antenna performance, and in this letter, we propose a corrugated two-slots array with a space larger than a wavelength in the E-plane, which can realize high radiation performance. A corrugated structure is loaded between slot elements as the secondary radiation source, and this slot source is based on slot dipole resonance mode to keep a low profile. Simulated and measured results both show high grating-lobe level drastically suppressed to less than -10 dB with the introduction of the corrugated grooves, compared to the case of flat two-slot array without grooves. Additionally, the antenna gain is significantly increased by about 9 dB, and half-power beamwidth (HPBW) in both E- and H-plane are narrowed as well. This letter is also considered as a reply to Appl. Phys. Lett., vol. 93, pp. 156101, Oct. 2008. |

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.
