Abstract | Two types of circular-polarized smart patch antenna arrays, namely patch antenna with seven hexagonal elements (PASHE) and patch antenna with seven circular elements (PASCE) for indoor mobile wireless computing are investigated. A comparison between simulated and measured reflection coefficient was made with consistent results. The finite element method (FEM) and optimization using a gradient algorithm was carried out to optimize these patch antennas' physical structures on a finite ground plane to achieve optimal directivity in elevation plane and antenna gain at 2.4GHz operating frequency. Switched parasitic technique enables the two patch antennas to steer a directional beam through six locations in azimuth with elevation of approximately 65/spl deg/ for the former and 70/spl deg/ for the latter respectively. The low profile and low cost characteristics along with the simplistic beam control system of these smart patch antennas are ideal prototypes for commercialization. |

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.
