Abstract | A compact concentric array radial line slot antenna (CA-RLSA) operating at Ku-band for high-power microwave (HPM) application is proposed in this paper. The efficiency of HPM-RLSA becomes lower as the aperture size reduces due to rotational asymmetry of the illumination. The HPM-CA-RLSA was designed to overcome this difficulty with notable power handing capacity. It is fed by circularly polarized TE11 coaxial waveguide mode to generate a rotational symmetric cylindrical wave excitation. Furthermore, the reflection canceling structure of this HPM-CA-RLSA is not only simpler than the one in the HPM-RLSA but also improves the frequency response performance. An antenna prototype with length of 8 cm and aperture diameter of 40 cm is designed, which has a gain of 32.0 dBi, reaching an aperture efficiency of 62.7%, and an axial ratio less than 0.5 dB at 12 GHz. The simulated results show that this antenna has a power handing capacity of more than 500 MW. |

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.
