Electronic equipment and multi-antenna system thereof

The invention discloses an electronic device and a multi-antenna system thereof. The system comprises at least two single antennas, and each single antenna comprises a reference ground, a radiator, a feed conductor and a grounding conductor. The first end of each feed conductor is electrically connected with a feed source, the second end of each feed conductor is electrically connected with the corresponding radiator, the first end of each grounding conductor is electrically connected with the radiator, the second end of each grounding conductor is electrically connected with the corresponding reference ground, and the reference grounds of the plurality of single antennas are conducted. According to the technical scheme, the reference grounds of the plurality of single antennas are conducted, so that a low-potential area is formed near the grounding conductors connected with the reference grounds, the interference of space coupling in the antenna system is offset, the transmission of radiation energy between
