Abstract | In this study, a convoluted and connecting unit structure to design a frequency selective surface (FSS) with miniaturised closely spaced dual-bandstop is presented. Using −10 dB transmissions as the threshold for operating bandwidth, the proposed FSS possesses two stopbands with central operating frequencies of 3.4 GHz and 4.9 GHz with bandwidths of 950 MHz (2.80–3.75 GHz) and 850 MHz (4.55–5.4 GHz), respectively, and a band ratio of just 1.44. The unit dimension of the proposed FSS is 0.069λ 1 × 0.069λ 1, where λ 1 represents the first resonant wavelength in free space. This FSS structure exhibits excellent miniaturisation properties. In addition, the proposed FSS exhibits excellent stability for both transverse electric (TE) and transverse magnetic (TM) polarisations under incident angles from 0° to 60°. Finally, the FSS sample was fabricated and measured. The simulation results are in good agreement with the measured results. The biggest innovation of this study is to use the old method to solve the new problem, that is, to realise the shielding of fifth-generation (5G) signal by using the method of convoluted and connecting FSS. The design will be of significance in further development of 5G communications. |

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.
