| 摘要 |
A rectangular substrate provided in a radio communication terminal includes a built-in antenna and a grounded conductor functioning as a current control conductor. The antenna is placed in the vicinity of one short side of the substrate, and the current control conductor is placed in a vicinity of the other short side of the substrate. When the substrate has, for example, a half wavelength, the current control conductor changes an effective length of the substrate to reduce a high-frequency induced current generated in the substrate. Therefore, the deterioration of the antenna characteristics influenced by the human body can be prevented. The invention is applicable to the radio communication terminal having two casings movably connected by a connector.
