| Abstract | This paper presents the design and analysis of the microstrip Yagi antenna appropriate for wireless fidelity (Wi-Fi) application. The antenna comprises of two elements which are driven and parasitic that consists of reflector and directors. The analysis has been carried out to identify the effects of each element to the performance of antenna that will achieve a high gain. A gain enhancement method using Yagi antenna concept is designed with array application. Two branches of microstrip Yagi antenna have been connected in a composite array format using corporate-feed network. The designed antenna with microstrip line feeding based on quarter wave impedance matching technique is simulated using Computer Simulation Tool (CST) Microwave Studio. The simulation result of return loss shown that the operating bandwidth at frequency range of 5.47–5.57 GHz coverage standard of IEEE 802.11 in 5 GHz Wi-Fi band between 5.15–5.875 GHz. The antenna is fabricated on the low cost FR-4 substrate with dielectric constant of 4.7 and thickness of 1.6 mm. Simple fabrication techniques can be utilized to the proposed antenna design due to the placing feeding network is on the same layer with the antenna patch elements. The microstrip Yagi antenna is measured using Vector Network Analyzer (VNA). Both the simulation and experimental results are compared and analyzed. |

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.
