| Zusammenfassung: | PURPOSE:To obtain satisfactory reception sensitivity by successively adjusting a voltage standing wave ratio corresponding to surrounding environments where the antenna is fitted. CONSTITUTION:A copper foil tape 31 for adjustment is provided at a reception part where slender two copper foil patterns 26 and 26 are parallelly arranged while returning them at the head part. Electrostatic capacity coupling is performed for these two copper foil patterns 26 and 26 at the base parts of the above copper foil patterns 26 and 26 or the nearby positions while interposing resist concerning this copper foil tape 31 for adjustment and further, this copper foil tape 31 for adjustment can be changed corresponding to a frequency corresponding to the antenna fitting position. |
