| Abstract | Three different designs of a dual band patch antenna have been investigated in this paper. By using u-slot patch geometry dual band operation has been obtained. The patch antenna has been designed and simulated in CST Microwave Studio. By studying the antenna parametrically, it has been observed in CST Microwave Studio how the antenna characteristics vary with the variation of its different parameters. This observation has provided us sufficient insight to optimize the antenna parameters to meet the design requirements. The proposed designs of the antenna operate in 3.65 GHz band which is common to all three designs but the second operating band is different. By varying the u-slot broadness the second frequency band can be shifted from 5.25 GHz to 5.76 GHz. Moreover, it can be brought to 2.45 GHz band by carefully adjusting the parameters of the antenna. The gain and directivity in 3.65 GHz band of one of the three designs have been improved in other two designs. The gain has been improved from 3.73 dB to 6.6 dB and the directivity from 6.44 dBi to 7.55 dBi in 3.65 GHz band. The operating frequencies of the proposed designs fall in IEEE802.11a (5.20 GHz and 5.775 GHz), IEEE802.11b (2.45 GHz) and IEEE802.11y (3.675 GHz) standards which would allow WLAN operation. This patch antenna has been intended to be used in portable devices that demand miniaturized constituent parts. |

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.
