Abstract | Here, a wideband patch antenna array with dual ±45° polarisations has been proposed and implemented in Ku-band for back-haul services. Stacked patches and full-corporate feeding technique are adopted for wideband performance. To achieve a high port isolation, feed networks of dual polarisations are physically separated and designed with a coupling cancellation technique. The experimental results show that the proposed antenna simultaneously covers a bandwidth of 13.3–16 GHz in terms of ∣S 11∣, ∣S 22∣<−12 dB and port isolation better than 30 dB. Furthermore, it has high gains >17.8 dBi as well as identical radiation patterns for ±45° dual polarisations. The proposed dual-polarised patch antenna array has features of low profile, low cost, light weight, and ease of fabrication, which is very promising for microwave back-haul applications. |

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.
