Abstract | This communication explores the super-wideband Koch snowflake fractal monopole slot antenna for different wireless/multiband applications. The antenna comprises of a modified star-shaped patch, a 50 Ω triangular tapered feedline, a partial slot loaded ground plane and an I-shaped parasitic element located beneath the radiating element. The self-similarity and space-filling features of Koch iteration technique have been employed at the triangular patch to acquire the antenna compactness and broadband performances. Further by placing a pair of symmetrical L-shaped slots and an inverted U-shaped slot in the ground plane, a super-wide-impedance bandwidth (BW) ( ∣ S 11 ∣ < − 10 dB ) of 650 MHz–20 GHz with a ratio BW of 30.7:7 is attained. The proposed antenna has a compact size of 17 × 29 × 0.787 mm3 and has a stable radiation pattern over the entire frequency spectrum. For pattern stability, an I-shaped parasitic element was utilised. Moreover, the typical antenna parameters such as return loss, gain, radiation pattern and group delay have been simulated and verified experimentally. Time-domain characteristics have also been studied. |

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.
