An antenna structure comprises a housing, a feed-in portion, a grounding portion, a first radiator and a second radiator. The housing is provided with a first radiation portion and a second radiationportion arranged at interval with the first radiation portion, the first radiation body and the second radiation body are arranged in the housing at intervals, when a current is fed in from the feed-in portion, the current flows through the first radiation portion and is earthed through the grounding portion to excite a first operating modal, at the same time, the current is coupled to the first radiation body through the first radiation portion to excite a second operating modal, when the current is fed in from the second radiation body, the second radiation body excites a third operating modal, and the current is coupled to the second radiation portion through the second radiation body to allow the second radiation portion to excite a fourth operating modal. The antenna structure has wide bandwidth. The present
