ABSTRACT:
The present invention relates to an antenna device disposed in a case and prevents antenna characteristics from being degraded by a human body. The antenna device is configured such that it comprises an antenna that is disposed in a first case unit, a passive element that is disposed in a second case unit coupled to the first case unit and that can obtain an antenna function due to capacitive coupling with the antenna, and a conductor (printed board) that is disposed in the second case unit to suppress radiations from the passive element to one side of the second case unit.
