The invention relates to a communication device. The communication device comprises an antenna system, a metal base and a metal cushion high post, wherein the antenna system at least comprises a first dual-polarized antenna and a first reflector, the first reflector is used for reflecting radiation energy of the first dual-polarized antenna, and the metal cushion high post is coupled between the antenna system and the metal base and is used for supporting the antenna system. The communication device is suitably applied to various indoor environments, and the problem of traditional poor communication quality caused by signal reflection and multi-path attenuation is solved.
