Abstract | In this Letter, the chessboard grid hollow substrate (CGHS) is firstly presented to enhance the scattering performance of circularly polarised metasurface antenna. Grounded structures and AMCs are designed into chessboard arrangement as radiator. The CGHS installed at the upper of original antenna diversifies the thickness of adjacent subarrays. In contrast to previous chessboard arrangements, the 180 ° ± 37 ° reflection phase difference could be more easily realised for radar cross-section (RCS) reduction (less than − 10 dB). By straightforwardly adjusting the reflection phase, this design realises a peak RCS reduction of − 31.6 dB at 14 GHz, dramatically reduces RCS from 7 to 20 GHz. Moreover, simulated results demonstrate CGHSs optimise the monostatic RCS reduction average at the operating bandwidth, approximately − 5 dB . Meanwhile, this design also yields a VSWR ≤ 2 impedance matching bandwidth at 9.14–11.76 GHz and a less than 3 dB axial ratio bandwidth at 9.76–10.66 GHz. |

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.
