摘要： A communication system includes a master communication device and slave communication devices. The master communication device obtains information indicative of communication characteristics. The communication system records a combination of the master communication device and at least one of the slave communication devices having a communication abnormality. The system finalizes an abnormal position where the abnormality is occurring when an abnormality-determined position is consistent with a recorded combination of the master communication device and the at least one of the slave communication devices having a communication abnormality.

摘要： The wireless communication apparatus includes a communicator that performs at least one of transmission of signals to an antenna and reception of the signals from the antenna through a microstrip line. The microstrip line is formed with a first stub provided on the side of the communicator and a second stub provided on the side of the antenna, which stubs have resonant characteristics.
