ABSTRACT:
An antenna device includes an antenna element, a high-frequency circuit connected to the antenna element, a first ground section connected to the high-frequency circuit, a reactance circuit connected to the first ground section, and a second ground section connected to the reactance circuit. Employing the structure above allows the antenna device to have a compact body and to easily control antenna characteristics, such as radiation characteristics and input impedance characteristics.
