<p>PROBLEM TO BE SOLVED: To provide a portable terminal equipped with a plane antenna capable of reducing the deviation of resonance frequencies in spite of the change of surrounding states, simplifying its incorporation into the portable terminal, and realizing its independency of the state of the polarization of the communicating party. SOLUTION: This portable terminal for transmitting data with the other equipment by radio communication is provided with a plane antenna as an antenna for communication with the other equipment. In this case, the metallic frame of a display or the like is used as a ground plate for the plane antenna, and a plate-shaped inverse F antenna 10 is also used for this antenna.</p> |
