| Abstract | A new design of a metallic dual-band electromagnetic band-gap (EBG) suitable to feed a reflector antenna for space multibeam applications is introduced in this letter. The EBG antenna is composed of double-layer frequency selective surfaces (FSS) arranged in the longitudinal direction and a square horn as a feed. First, we devise a technique to adapt the dual-band EBG antenna characteristics for this space application, which requires the same EBG phase center and the same radiation patterns for both frequency bands. Then, a dual-band EBG antenna has been designed. Finally, a prototype is realized, and the experimental measurements are compared with success to the simulated ones. The same phase center has been obtained at 5 and 7.5 GHz. This antenna is suitable to feed a reflector antenna with a focal-length-to-diameter (F/D) ratio of 1.2. The performances of the offset reflector fed by this antenna are good with a maximum efficiency about 77% and with sidelobes levels always better than -22 dB for both frequency bands. |

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.
