无线IC器件
摘要：
本发明得到一种可控制收发信号的增益的无线IC器件。该无线IC器件包括：无线IC芯片电电路基板(4)，该馈电电路基板(4)与无线IC芯片(5)连接，且具有包含至少一个线圈图案(23)的馈电电路；及辐射板(3)，该辐射板(3)将由馈电电路基板(4)提供的发送信号进行辐射，并且对接收信号进行接收并将其提供给馈电电路基板(4)。辐射板(3)的一部分具有开口部(7)和与该开口部(7)连接的狭缝部(6)，从所述线圈图案(23)的卷绕轴方向俯视时，辐射板(3)的开口部(7)和线圈图案(23)的内侧区域重叠，且内侧区域和开口部(7)的面积大致相同。(5)，该无线IC芯片(5)处理预定的无线信号；馈
摘要（英）：

To provide a wireless IC device capable of controlling the gain of transmission and reception signals. A wireless IC device includes a wireless IC chip (5) processing a certain radio signal; a power-supply circuit board (4) that is connected to the wireless IC chip (5) and that includes a power supply circuit including at least one coil pattern (23); and a radiation plate (3) radiating a transmission signal supplied from the power-supply circuit board (4) and/or receiving a reception signal to supply the reception signal to the power-supply circuit board (4). The radiation plate (3) includes an opening (7) provided in a part thereof and a slit (6) linking to the opening (7). Viewed in plan from the direction of the winding axis of the coil pattern (23), the opening (7) in the radiation plate (3) is overlapped with an inner area of the coil pattern (23) and the area of the inner area is approximately the same as that of opening (7).
