This paper presents an analysis of different multi-feed EBG solutions, in order to choose the best one which provides overlapped apertures and promises good functioning as a reflector focal array. Two main structures will be studied: the matched and unmatched antenna. Both structures present different kinds of interference and coupling between feeds which disturb the performances of the antenna, especially the radiation. That is why suited filtering functions for each solution will be studied in order to isolate feeds and reconstruct the disturbed radiation. The investigation of all structures and their required filtering functions will lead us to the final promising solution which is the matched multi-feed EBG antenna.
