  • Patent number: 8774012
    Abstract: A disclosed wireless communication device performing transmission and reception in a time-division manner includes an antenna, a transmission unit, a reception unit, a transmission/reception switchover unit, a first path switchover unit, a directional coupler, a second path switchover unit, a first fault diagnosis unit, and a second fault diagnosis unit. The second fault diagnosis unit causes the second path switchover unit to form a reflection signal input path; causes a second transmission signal level-adjusted for fault diagnosis to be outputted from the transmission unit; acquires a signal level of a reflection signal from the antenna inputted from the directional coupler into the reception unit; and determines whether or not a transmission radio wave is normally emitted from the antenna based on the signal level of the reflection signal.
