Design of a multi-feed EBG antenna as a focal array for Ka-band space applications
Abstract : This paper is dedicated to the design of a multi-feed matched EBG antenna, providing overlapped beams, as a reflector focal array for Ka-band space applications. The architecture must ensure the coverage of Europe through 40 spots "Agora mission proposed by CNES" with a 4x reuse scheme (2 linear polarizations and 2 frequency channels). As a first step, the EBG antenna will be studied in mono-feed configuration. Then, the simulation of the multi-feed EBG antenna will show us its suffering from the mutual coupling between feeds which disturbs the radiation. Once the S-parameters of the multi-feed antenna are extracted, suited filters will be connected to the antenna in order to isolate channels and reconstruct the radiation. Finally, the whole system (EBG antenna illuminating a reflector) will be studied in order to characterize the coverage.
