Abstract
When the antenna is extended, the length of the ½&lgr; whip antenna,operates as an antenna thus causing only a negligible quantity of high-frequency currents to flow into the ground for the first circuit board,. When the antenna is housed, the entire length of a ¼&lgr; helical antenna,and a metalized ¼&lgr; radial of the first enclosure,operates as an antenna thus causing only a negligible quantity of high-frequency currents to flow into the ground for the first circuit board 106. Because the length of the antenna is ½&lgr; both when the antenna is extended and housed, only a negligible quantity of high-frequency currents to flow into the high-frequency circuit via the ground for the first circuit board
