| Abstract | This paper presents the four iterative circular shaped fractal antenna and its backscattering RCS with respect to iteration. First, the solid circular patch antenna has been designed on substrate $ε_{r}$ = 2.2, h=0.787 mm with a = 40.766 mm and aspect ratio b/a = 0.98. The antenna has been simulated using FDTD method. The resonant frequency of this antenna has been observed at 1.42 GHz. The four iterative circular fractal antennas have also been designed with same substrate and dimension. This multi-band fractal antenna has been simulated, fabricated and tested. It has been observed experimentally that antenna is working on multiple frequencies. The size reduction of antenna is evident because first resonant frequency is shifted to 1.09 GHz in comparison to solid simple patch at 1.42 GHz. The experimental resonant frequencies of fractal antenna are 1.09 GHz, 1.65 GHz, 2.92 GHz and 4.485 GHz. The experimental and simulated resonant frequencies of antenna are in good agreement. The backscattering power with respect to iteration has been analyzed. It is observed that four iterative structure offers less backscattering power. |

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.
