Reader/writer device and automatic ticket gate including the same for checking ticket
Abstract:
An antenna unit prevents a communication error by suppressing side lobes formed by an antenna coil segment of a reader/writer device. The antenna unit (200) is used for a reader/writer device (20) whose signal processing circuits (210) and (220) communicate with an IC card (10) via electromagnetic waves, wherein an antenna coil (100) of the IC card (10) relatively gets close to the antenna unit (200). The antenna unit (200) includes the antenna coil segment which forms a loop antenna (202) on a substrate (201) and conductor segments (203) at the periphery of the antenna coil on substantially the same plane of the antenna coil.
Abstract(Chinese):

天线单元通过抑制由读写器设备的天线线圈段形成的旁瓣来防止通信错误。 天线单元（200）用于其信号处理电路（210）和（220）经由电磁波与IC卡（10）通信的读/写器设备（20），其中IC的天线线圈（100） 卡（10）相对靠近天线单元（200）。 天线单元（200）包括在基板（201）上形成环形天线（202）的天线线圈段和位于天线线圈的基本相同平面上的天线线圈周围的导体段（203）。
