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.
Claims18
An antenna device comprising:
- 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, the passive element acquiring an antenna function due to capacitive coupling with the antenna;
- and
- a conductor that is disposed in the second case unit to suppress radiations from the passive element to one side of the second case unit.
A radio communication device having a first case unit and a second case unit, the radio communication device comprising:
- an antenna that is disposed in the first case unit;
- a passive element that is disposed in the second case unit coupled to the first case unit, the passive element acquiring an antenna function due to capacitive coupling with the antenna;
- and
- a conductor that is disposed in the second case unit in order to suppress radiations from the passive element to one side of the second case unit.
