<P>PROBLEM TO BE SOLVED: To provide an adjustment method of an antenna device, which expands an adjustment range of a resonance frequency in the antenna device, and has narrow tolerance to a center frequency of an antenna, and to provide a method for manufacturing thereof. <P>SOLUTION: The invention provides the antenna device having: an antenna part 3; and an adjustment pattern 2 to be connected to the antenna part 3, wherein the adjustment pattern 2 is formed with a first line and a second line crossing mutually while the crossing point is electrically connetionless, and also with a third line connecting the first and second lines and non-crossing with the above crossing point, a fourth line connecting the first and second lines and being on the opposite side of the third line interposing the above crossing point, and a fifth line connecting between one ends of the third and fourth lines. The other ends of the third and fourth lines are connected to a loop pattern, and either one of the first line and the second line, or the third line and the fourth line between the first and second lines is cut off to adjust the resonance frequency of the antenna device 1. <P>COPYRIGHT: (C)2010,JPO&INPIT |
