The invention relates to the technical field of communication, and particularly relates to an antenna component and a mobile terminal. The antenna component comprises a rear cover provided with a closed
metal middle frame free of
breakpoint, and a circuit board which is arranged in the rear cover. The
metal middle frame comprises a top plate and a side plate which curvely extends from the
tail end of the top plate. The top plate is used for forming a diversity antenna. The circuit board is located in the
metal middle frame. The circuit board comprises a grounding point and a feeding point. The feeding point and the grounding point are respectively electrically connected with the metal middle frame. A clearance area is arranged between the circuit board and the side plate along the extending direction of the circuit board. The circuit board and the clearance area form a three-in-one antenna. The three-in-one antenna is composed of a
GPS antenna, a WIFI-2.4G antenna and a WIFI-5G antenna. According to the invention, the three-in-one antenna is arranged on the side; the diversity antenna is arranged on the top plate; the
layout space of the diversity antenna is increased; the design difficulty of the diversity antenna is reduced; and the performance of the diversity antenna is ensured.
