| Abstract | A novel method used to design multiple targets microwave power transmission antenna array that could transmit power wirelessly to discrete targets with different power division ratios is introduced in this study. The maximal transmission efficiency and the precise power division ratio could be achieved simultaneously by utilising the basis functions, which are optimised for high-transmission efficiency, and the power division ratio is achieved precisely by investigating the transmission coefficients related to each basis function carefully. Two antenna arrays working at 2.45 GHz are designed and fabricated to verify the method. The power division ratios of array 1 and array 2 are designed to be 1:1 and 1:2 when the transmission distance is 10 cm, and the measured results are 1:1 and 1:2.1, respectively. |

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.
