Abstract:
A communication device includes a ground plane, an antenna array, and an EBG (Electromagnetic Band Gap) structure. The antenna array includes a plurality of antenna elements. The EBG structure includes a plurality of EBG units. The EBG units are coupled to the ground plane. The antenna array is surrounded by the EBG structure. The EBG structure is configured to suppress the front-to-back ratio of the radiation efficiency of the antenna array.
