Description

供插入式双界面智能卡使用的天线 技术领域
本发明涉及一种天线， 尤其涉及一种供插入式（plug-in)双界面智能卡的非接触部分使 用的天线。
背景技术
目前具有非接触功能的 IC卡， 例如 ID- 1尺寸的双界面智能卡， 其射频天线线圈 111通 常布置在卡片片基 122内， 天线线圈 111的两个接点直接与智能卡的芯片 123引线连接， 如 图 1所示。
目前随着智能 IC卡应用的不断深入， 双界面智能 IC卡由于具有两个工作界面， 特别是 其非接触应用方式， 使用方便、 快捷， 所以应用更加广泛。 特别是将其应用于手机等嵌入式 设备实现移动支付、 身份认证等， 这些应用将给人们的生活带来便利。
双界面智能卡在手机中的使用有其特殊之处。 以 SIM卡为例， 双界面的 SIM卡， 其接触 界面通过 siM卡槽， 由手机为其提供 vcc、 κ、 ι/ο等接触界面工作所需的电信号； 但双界 面 SIM卡的非接触界面需要射频天线为其工作提供时钟、 数据等信号， 对于电源信号， 若手 机处于开机状态， 电源由 vcc提供； 若手机处于关机状态， 电源则由射频天线提供。 然而现 行的将 ID- 1卡片的天线布置在片基内的方案已不能满足在手机等嵌入式设备中的应用要求。
目前， 在日本、韩国等国家开展的基于手机的移动支付方案中， 采用了改造手机的方案。 将具有消费功能的智能 ic卡置于手机内，其射频天线布置在手机的主板或专用的手机电池背 面，天线与智能 IC卡通过专门设计的触点连接在一起。这是一种成本较高的解决方案， 它涉 及手机的改造。 这种方案在中国的移动通信应用环境下， 手机的改造成本显得很明显， 若用 户要使用移动支付功能就需要重新购买有移动支付功能的手机。因此，用户的使用成本很高， 也就限制了移动支付业务的幵展。
发明内容
为解决手机改造成本高的问题， 本发明提供一种附加在插入式（plug- in)智能卡表面的 天线组件。
在这种供插入式双界面智能卡的非接触界面使用的天线中， 插入式智能卡包括卡模块和 片基； 天线包括基材、 固定在基材第一表面上的天线线圈、 以及第一和第二天线引脚。 上述 基材包括配合卡模块的结构、 第二表面上的第一和第二触点、 以及第一和第二过孔， 第一和 第二触点和配合卡模块的结构布置在所述基材与插入式智能卡的触点对应的位置上， 第一和 第二天线引脚分别通过第一和第二过孔连接到第一和第二触点上。
上述配合卡模块的结构是由布置在上述基材上与卡模块的触点对应的各个位置上通过过 孔两面连通的触点形成的。
当天线附着到插入式智能卡上时， 上述基材第二表面上的触点与插入式智能卡上各个对 应触点相连接。
当附有天线的插入式智能卡插入卡槽时， 卡槽各触点与天线基材第一表面上的对应触点 相接触， 所述的接触连接通过所述两面连通的触点连接到插入式智能卡的对应触点上。
配合卡模块的结构是在上述基材与智能卡的部分触点对应的位置上为这些触点留出的窗
□。
当天线附着到插入式智能卡上时， 上述智能卡的部分触点通过所述窗口暴露出来。
当附有天线的插入式智能卡插入卡槽时， 卡槽各触点与插入式智能卡上的对应触点直接 接触。 '
上述天线通过粘胶、 热熔或焊接等各种连接方式附着到插入式智能卡上。
插入式智能卡芯片的天线引脚引出的触点布置在插入式智能卡的卡模块上。
插入式智能卡芯片的天线引脚引出的触点布置在插入式智能卡的卡片边缘。
本发明的突出优点在于， 在插入式（plug_in)双界面智能卡上附加天线， 使为 plug - in 双界面智能卡的非接触界面提供射频天线变得更为方便快捷， 进而为基于非接触应用方式的 新业务的引入节约了成本。

图 7是智能卡芯片上的天线引脚按照另一个实施例引出触点的俯视图。
具体实施方式
本发明的技术方案是， 在插入式（plug- in)双界面智能卡表面外接天线， 从而获得双界 面智能卡非接触部分工作所需的能量及时钟、 数据信号， 其中能量视手机是否开机由 VCC或 天线提供。 具有非接触功能的双界面智能 IC卡， 例如 SIM、 UIM、 PI 卡等， 它们均为符合 IS07816-1规范的 plug-in类型的小卡。 将这样的智能卡用于手机时， 为解决非接触部分的 正常工作而采取在智能卡上附加天线的技术方案。 当采用该方案的双界面智能卡用于手机等 嵌入式设备中的时候， 其非接触界面通过天线， 可以实现移动支付、 近距离通信等功能。
在现行智能 IC卡规范（如 IS0/IEC 7816-3)中， C4、 C8脚保留。这为插入式（plug- in) 的非接触式 IC卡的天线线圈的接入提供了通路。现在参照图 2来描述双界面智能卡芯片上的 天线引脚与模块触点的连接。 在将智能卡芯片 23封装为智能卡 2上的模块 21的过程中， 芯 片 23的天线引脚 LA、 LB分别通过引线 24、 28与模块 21的 C4、 C8脚连接。封装后的结果如 图 2中 plug- in尺寸的卡片 2所示。 而后， 非接触部分所需的天线线圈通过下面将要描述的 方式与模块 21的触点 C4、 C8连接， 从而实现为非接触部分提供射频信号。
天线线圈需要附着在双界面智能卡的插入式卡片上， 比如采用胶粘、 热熔、 焊接或者其 他方式与智能卡的片基 22结合在一起。 可视为在插入式卡片上附着一层天线。
图 3是天线组件和插入式卡片两者还未结合时的配置透视图。 如图所示， 左侧的天线组 件 1包括天线线圈 11、 柔性或软性基材 12、 接 C4的天线引脚 14和接 C8的天线引脚 18。 进 一步地， 基材 12包括配合卡模块的结构 201、 下表面上的触点 C4b和 C8b、 过孔 204和 208。 右侧的插入式卡片 2包括卡模块 21和片基 22。 天线线圈 11是以印刷、 蚀刻、 线绕或者其他 方式制造在软性基材 12上表面的， 在本实施例中采用薄膜作为软性基材 12。 天线线圈 11的 设计参数， 如 Q、 L、 R等参数， 通过实际实验来确定， 参数需要符合 IS0/IEC 14443及智能 卡芯片对于天线的要求。 由于薄膜是非导电体， 为了实现天线引脚 14和天线引脚 18分别与 卡模块 21的触点 C8和 C4接触， 天线引脚 18穿过过孔 208在天线基材下表面延伸至与触点 C8对应的位置，并在此位置制造金属触点 C8b;天线引脚 14则在天线基材上表面直接延伸至 与触点 C4对应的位置， 并穿过过孔 204， 在此位置下表面制造金属触点 C4b。 图 4是根据本发明第一个实施例的配合卡模块的结构的俯视图。 制造好如图 3所示的天 线组件后， 为实现 IC卡卡槽触点（图中未示出）与卡模块的各触点接触， 在天线基材与卡模 块的触点 Cl、 C2、 C3、 C5、 C6和 C7对应的各个位置上带有两面连通的符合 IS07816- 1要求 的触点。 如图 4所示， 天线基材上表面 12a具有触点 Cla、 C2a、 C3a、 C5a、 C6a和 C7a， 在 基材下表面加工与这些触点相对应的触点， 上下表面的触点通过过孔连接。 因此， 当天线基 材下表面的各个触点分别与插入式卡片模块的各个触点接触时， 一旦天线基材上表面的各个 触点分别与 IC卡卡槽的各触点接触， 就建立起 IC卡卡槽上各个触点与插入式卡片模块上的 触点 Cl、 C2、 C3、 C5、 C6和 C7之间的对应连接。 其中， 触点 C4和 C8用于与天线的两个接 点连接。 可见， 由这些两面连通的触点形成的配合卡模块的结构 201， 是在原 IC卡卡槽触点 与卡模块的各触点之间增加的续接导电体。
图 5是根据本发明第二个实施例的配合卡模块的结构的俯视图。 制造好如图 3所示的天 线组件后， 为实现 IC卡卡槽触点（图中未示出）与卡模块的各触点接触， 在天线基材上配合 卡模块的结构 201所在的位置铳出一个窗口， 给卡模块的触点 Cl、 C2、 C3、 C5、 C6和 C7留 出空间， 如图 5所示。 因此， 一旦天线基材附着到插入式卡片的恰当位置上， 卡模块的触点 Cl、 C2、 C3、 C5、 C6和 C7就可以暴露出来。
图 6是天线组件和插入式卡片两者结合起来的配置透视图。
按照第一个实施例， 在配合卡模块的结构 201 由两面连通的触点形成的情况下， 如图 6 所示， 当天线组件 1附着在插入式卡片 2上时， 天线基材 12下表面的所有触点与卡模块 21 上的 8个触点分别对齐， 在保证两方触点良好接触的情况下， 天线组件 1和插入式卡片 2通 过粘胶、热熔、焊接等方式结合在一起。这种在天线基材上制造上下表面连通的触点的方式， 使插入式卡片置入 IC卡槽时，卡槽的各个触点与天线基材上表面的触点 Cla、 C2a、 C3a、 C5a、 C6a和 C7a对应接触， 天线基材上表面的触点接触也通过过孔与天线基材下表面的相应触点 连通， 而天线基材下表面的各个触点在基材与卡模块结合在一起时与卡模块的 C1至 C8触点 紧密地对应接触。 也就是说， 卡槽触点与卡模块的触点之间的连接是通过天线基材薄膜上两 面连通的触点来转接的。 .
按照第二个实施例， 在配合卡模块的结构 201是开口的情况下， 同样参照图 6， 天线组 件 1通过粘胶、 热熔、 焊接等方式与插入式卡片 2结合起来， 而且在两者结合时要保证天线 基材 12上的开口的顶端对齐卡模块 21的顶端， 以便露出卡模块的触点 Cl、 C2、 C3、 C5、 C6 和 C7， 同时保证卡模块的触点 C4、 C8与天线基材下表面的触点 C4b、 C8b对位准确并可靠接 触。这种在天线基材上开窗口的方式， 使插入式卡片置入 IC卡槽时， 卡槽的触点直接与卡模 块的触点 Cl、 C2、 C3、 C5、 C6和 C7对应接触。
图 7是智能卡芯片上的天线引脚按照另一个实施例引出触点的俯视图。 在该实施例中， 智能卡芯片的天线引脚通过与如上所述的方案不同的方式引出。将天线引脚 LA、 LB引至插入 式智能卡 2的卡片边缘， 并形成与卡模块 21分开的触点 C4' 、 C8' 。 在这种情况下， 设计 天线组件的时候需要相应地改变天线组件的触点位置。
由于插入式智能卡工作时置于卡槽内， 这要求插入式卡片与附着的天线叠加在一起的总 厚度小于 1腿。
显然， 本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范 围。 这样， 倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内， 则 本发明也意图包含这些改动和变型在内。
