Abstract
The present invention provides a communication terminal that enables precise communications with optimum receive sensitivity at any time regardless of any change in peripheral environments of an antenna thereof. The communication terminal including means for transmitting and receiving radio waves is provided with a training mechanism for enabling the communication terminal itself to conduct training mode for tuning receive sensitivity, and switching mechanism for switching between normal communication mode and the training mode. The communication terminal is particularly useful as a communication terminal for automobile in the Intelligent Transport System or the like.
