| Abstract | This study presents four integrated Fibonacci-type Global System for Mobile (GSM) ultra-wideband (UWB) antennas with single, dual, and triple band-notched characteristics. These antennas have been designed to control potential interference in Wi-Max and WLAN bands. The antenna operates in the 900 MHz GSM band and also in the 3.2–11.9 GHz extended UWB band. The 900 MHz operating band can be further tuned to get the antenna to operate in a specific GSM band. Triple notches have been created at frequencies within several bands, such as 3.4 GHz Wi-Max (3.06–3.54 GHz), 4.23 GHz WLAN (3.59–4.86 GHz), and 6.35 GHz (5.93–7.15 GHz) with voltage standing wave ratio (VSWR) levels of 7.9, 11.3, and 7, respectively. These notch bands are also tuneable to some extent. The measured gain varies from −1.92 to 10.2 dBi. Measured radiation patterns of the antenna are also presented to validate its performance. The integrated antenna has a radiation efficiency in the range of 78–98% in the UWB and 98% in the GSM band. The fidelity factor in time domain varies between 0.76 and 0.84, depending on the orientation of the antenna. This research confirms that the Fibonacci monopole can be used as a multiband antenna in GSM and UWB bands. |

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.
