Abstract | This paper presents a new printed slot monopole antenna for ultra-wideband applications. The proposed antenna is a rectangular slot excited by a 50 Ω microstrip line. Techniques to expand the impedance bandwidth of a simple rectangular monopole antenna are given. The experimental results show that the presented structure shows an ultra wide impedance bandwidth behaviour based on S11 ≤−10 dB, covering frequency range from 1.82 to 12.59 GHz, 148%. Current density distribution on the antenna was also computed to gain a better insight of its behaviour. The antenna radiation pattern and gain are measured and presented. The measured results are in good agreement with the simulation results. The measured results indicate that the antenna radiation patterns are stably omnidirectional over the entire frequency range of interest. The measured gains range from 2.8 to 6.3 dBi versus operating frequency. |

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.
