摘要：
A method for manufacturing an antenna device may include a first step of forming an antenna circuit so that the resonance frequency of the antenna circuit will be lower than an oscillation frequency of the reader/writer. The antenna circuit includes an antenna coil that receives the magnetic field transmitted from the reader/writer and a capacitor electrically connected to the antenna coil. The manufacturing method also includes a second step of affixing a magnetic sheet to the antenna coil via an adhesive. The magnetic sheet is at a face-to-face position with respect to the antenna coil and is configured to change the inductance of the antenna coil. The adhesive is of a film thickness to change the inductance so that the resonance frequency of the resonance circuit will be coincident with the oscillation frequency depending on the spacing between the antenna coil and the magnetic sheet.
摘要（中）：
天线装置的制造方法可以包括形成天线电路的第一步骤，使得天线电路的谐振频率将低于读取器/写入器的振荡频率。 天线电路包括接收从读取器/写入器发送的磁场的天线线圈和电连接到天线线圈的电容器。 该制造方法还包括通过粘合剂将磁性片固定到天线线圈的第二步骤。 磁性片相对于天线线圈处于面对面位置，并且被配置为改变天线线圈的电感。 粘合剂具有改变电感的膜厚度，使得谐振电路的谐振频率将与根据天线线圈和磁性片之间的间隔的振荡频率一致。
