Antenna system and electronic device

The invention discloses an antenna system. The technical problem of poor performance of an antenna system in low frequency band in the prior art is solved. The antenna system is arranged in an electronic device. The electronic device has a short side and a long side. The length of the short side is less than the length of the long side. The antenna system comprises a first antenna and a second antenna. The first antenna is used for transmitting and receiving data. The first antenna is an antenna whose electrical length is equal to electrical length required by the resonance of the first antenna. The second antenna is arranged on the short side and is used for receiving data. The second antenna is an antenna whose electrical length is less than electrical length required by the resonance of the second antenna. The invention further discloses the corresponding electronic device. 本申请公开了种天线系统，用于解决现有技术中天线系统在低频段的性能较差的技术问题，所述天线系统设置于电子设备中，所述电子设备具有短侧边与长侧边，所述短侧边的长度小于所述长侧边的长度，所述天线系统包括：第天线，设置于所述短侧边，用于发送和接收数据；其中，所述第天线为电长度
