| 摘要 |
The invention provides a compact and light-weight antenna device for use in a mobile telephone requiring a wide frequency band. An antenna device (10) includes a first printed circuit board (11) and a ground plate (12) generally arranged in parallel, and a second printed circuit board (13) arranged vertically between the first printed circuit board (11) and the ground plate (12), and an antenna body (14) mounted on the second printed circuit board (13). A capacitive load conductor (15) is mounted on the first printed circuit board (11), and a surface electrode (16), a ground electrode (17) and a transmission line (18) are mounted on the second printed circuit board (13). The antenna body (14) is provided with terminals (19) and (21) connected to both ends of a conductor (not shown). <IMAGE> |
