Summary:
EBG (Electromagnetic Band-Gap) Structures composed of metal patches arranged at small intervals have the frequency-band-rejection characteristics. Thus, it can reduce the undesired electromagnetic waves [1]. From the unique characteristics, EBG structures have been studied to apply to antennas for the suppression of the mutual coupling and the improvement of the radiation property [2][3]. The mutual coupling suppression property by two-dimensionally arranged EBG structures was already clarified [4]. In this paper, a three-dimensionally arranged EBG structure is proposed. And, the effects of the arrangement method of the EBG elements on the suppression characteristics of the mutual coupling are studied. The paper first explains the suppression effects of a two-dimensionally arranged EBG structure on mutual coupling. Then, the effects in the case of the three-dimensionally arranged EBG will be explained. Finally, the optimum arrangement method of the EBG structure is presented.
