An antenna device includes a ground conductor; a ground conductor extension that is connected to the ground conductor; and an antenna element that is connected to the ground conductor and that operates in both a first frequency band and a second frequency band higher than the first frequency band, the ground conductor and the ground conductor extension having a length that is &#xbc; of a wavelength of a frequency included in a middle range between the first frequency band and the second frequency band and that is not a natural number multiple of &#xbc; of a wavelength of the first frequency band.

Antenna device

A wireless mobile device is used with the wireless mobile device mounted on a body of a user and includes a first wireless processor that performs wireless signal processing on a signal for a data communication in a first wireless system, a second wireless processor that performs wireless signal processing on a signal for a voice call in a second wireless system having a higher priority than a priority of the first wireless system, and a controller that, when a data communication in the first wireless system and a voice call in the second wireless system occurred at the same time, in a close-to-head state in which the wireless mobile device is brought close to a head of a user, reduces transmission power with which the first wireless processor outputs a transmission signal.
