An antenna structure includes a metal shell including a grounded middle frame provided with a main body and sides bent and extending from two sides of the main body and a radiating part serving as an antenna radiating body. The radiating part forms an insulation filled gap with the middle frame. Two ends of the radiating part are arranged opposed to each other for forming an insulation filled breaking joint. A circuit board is arranged below the metal shell, and one side of the circuit board adjacent to the radiating part forms a clearance zone between the circuit board and the radiating part.

An antenna apparatus includes a conductive radiating element, a conductive member, and a first impedance circuit. The first impedance circuit includes a first parallel resonant circuit (an LC parallel resonant circuit) and is directly connected between the radiating element and the conductive member (the conductor plate). Since the first parallel resonant circuit has high impedance in its resonant frequency band and is equivalently in an open state, one end of the radiating element is opened in the resonant frequency band. Accordingly, the radiating element defines and functions as a standing-wave antenna that contributes to electric-field radiation and a loop portion including the radiating element, the conductive member, and the first impedance circuit defines and functions as a magnetic-field radiation antenna that contributes to magnetic-field radiation.
