| Abstract | This study presents an antenna design that operates at the three bands of the Global Positioning System (GPS) receiver. The optimised Minkowski island fractal structure combined with the central window is used to design the radiation surface to reduce the size and adjust the resonance frequencies of the antenna. The antenna was designed, and simulated by HFSS computer code, and was fabricated on microwave laminate FR4-epoxy by fast laser prototyping. The resulting fractal antenna has been operating at three GPS-bands: f L2 = 1.227, f L5 = 1.176, and f L1 = 1.575 GHz, with return loss S 11 < −15 dB, bandwidths BW > 21.5 MHz, for VSWR < 2, at 50-Ω input impedance, the power gains ∼2.4, 2.85, and 4.2 dBi, and axial ratio of right-handed circular polarisation 1.5, 03, and 06 dB at f L5, f L2, and f L1, respectively. The simulated and experimental results agree favourable. |

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.
