1. A communication device comprising:
- a measurement portion configured to measure a reflection coefficient of an antenna that performs proximity wireless communication, during transmission of a transmission signal by the antenna;
a judgment portion configured to judge whether a value of the reflection coefficient measured by the measurement portion changes exceeding a value of a reflection coefficient of the antenna in a normal state and a predetermined threshold value; and
a communication control portion configured to stop the transmission of the transmission signal from the antenna when the value of the reflection coefficient measured by the measurement portion changes exceeding the value of the reflection coefficient of the antenna in the normal state and the predetermined threshold value as a result of the judgment of the judgment portion.

7. A judgment method comprising:
-
measuring a reflection coefficient of an antenna that performs proximity wireless communication, during transmission of a transmission signal by the antenna; judging whether a value of the reflection coefficient measured in the measurement step changes exceeding a value of a reflection coefficient of the antenna in a normal state and a predetermined threshold value; and stopping the transmission of the transmission signal from the antenna when the measured value of the reflection coefficient changes exceeding the value of the reflection coefficient of the antenna in the normal state and the predetermined threshold value as a result of the judgment of the judgment portion. - View Dependent Claims (8, 9, 10, 11)
