  • Patent number: 10333198
    Abstract: 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.
