PROBLEM TO BE SOLVED: To provide a small portable radio terminal antenna system capable of reducing the influence of user's hands exerted on an antenna, reducing a deterioration in antenna characteristic due to the hands and miniaturizing a portable radio terminal. SOLUTION: A portable radio set 1 is provided with a display part 2 and a key part 3, talking is made available by a receiving part 6 and a transmitting part 7 and a connector 4 and a connector cover 5 are arranged on the lower part of a casing. The connector 4 is used for external input/output or the like, but when the connector 4 is not used, the connector 4 is covered with the connector cover 5 for preventing the connector 4 from dirt or damage. A connector holding part 8 is formed between the connector cover 5 and the miniature radio set 1 so as not to lose the connector cover 5 even when the connector cover 5 is detached from the connector 4. An antenna element is built in the connector cover 5 and connected to a radio part by a feeding part through the connector holding part 8. COPYRIGHT: (C)2004,JPO&NCIPI
