摘要：
An antenna device of an embodiment includes: an antenna having a feeding point and an end portion apart from the feeding point, the end portion being an open end; a variable impedance matching circuit connected to the antenna at the feeding point; a probe placed in such a position that the distance from the end portion to a tip of the probe is equal to or shorter than one eighth of the wavelength corresponding to the maximum radio frequency used in the antenna device; and a controller that is connected to the probe, and controls the variable impedance matching circuit, based on an electrical signal measured with the probe.
