| Abstract | In this Letter, a differential-fed planar antenna system is presented with large isolation between transmission and reception ports for full-duplex applications. The proposed system contains two antenna pairs, each of which is composed of two identical single-ended microstrip patch antennas operating at 12 GHz. Each element in the array is fed 180° out-of-phase by utilising rat-race hybrid couplers making the whole system differential-fed. The patch antenna array and the hybrid ring couplers are designed on two separate substrate materials with the ground plane in between. Simulation results show high isolation S 21 < − 70 dB through the entire band of interest while measured results approach S 21 < − 50 dB in a reflective environment. The design also exhibits good impedance matching, reasonable gain values, and high efficiency. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
