Abstract
An antenna device is provided with an antenna element including a base, an inductance adjustment pattern that is formed on the upper surface and a side surface of the base and has a substantially U-shape, a capacitance adjustment pattern that is formed on the upper surface of the base and is placed to face the inductance adjustment pattern, and first to third terminal electrodes provided on the bottom surface of the base. The antenna element is installed between the first side and the second side of the ground pattern that form the two facing sides of the antenna mounting region. One end of the inductance adjustment pattern is connected to the feed line, the other end of the inductance adjustment pattern is connected to the first side of the ground pattern, and the third terminal electrode is connected to the second side of the ground pattern.
