Abstract | The design results of an H-shaped fractal antenna for application in multi-band microbolometers and the thermal performance estimation result of the microbolometer are reported. The H-shaped fractal antenna has been designed for wavelengths of 25 and 150 μm based on a dipole antenna formula and finite element method (FEM) simulation. Simulation results show that the absorption peaks exist at 27 and 150 μm. To verify the absorption characteristics of the designed antenna, the antenna was fabricated and the absorption characteristics for the x-polarised incident wave radiated from the + z-direction were measured. The measured transmittance dips at 27 and 146 μm almost agreed with the absorption peaks of the simulation results. The thermal performance estimation of an H-shaped fractal antenna-coupled VO2 microbolometer and obtained voltage sensitivities of 0.63 and 4.81 mV/(W/m2) at 27 and 150 μm absorption peaks, respectively, are also presented. |

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.
