[0002] 背景 [0002] BACKGROUND

[0003] 已经出现了允许在彼此接近的无线便携式设备(特别是薄型便携式电子设备)之间的近场耦合(诸如无线功率传输(WPT)和近场通信(NFC))。 [0003] have been allowed to close to each other between a wireless portable device (especially a portable electronic device thinner) near-field coupling (such as a wireless power transfer (the WPT) and Near Field Communication (NFC)). 近场耦合功能使用每个设备中的射频(RF)天线来发送和接收电磁信号。 Near field coupling function for sending and receiving electromagnetic signals using a radio frequency device each (RF) antenna. 由于用户需求以及/或者出于审美原因,这些便携式无线设备中的许多是小型的,并且随着市场发展而变得更小,并且趋于在从侧面观看时具有夸大的宽高比。 Due to user demand and / or for aesthetic reasons, these portable wireless devices many of which are small, and as the market becomes smaller, and tend to have an exaggerated aspect ratio when viewed from the side. 结果,许多薄型的便携式设备结合有平板天线,平板天线使用导电材料的线圈作为其辐射天线用于近场耦合功能。 As a result, many of the portable device incorporating a thin patch antenna, a patch antenna using a coil of conductive material as an antenna for radiating near-field coupling function.

[0004] 与此同时,(电容性)邻域传感器可用于具有内置无线广域网(WWAN)(诸如第三代或第四代(3G/4G)数字无线电)的平板电脑以便传递诸如特定吸收率(SAR)这样的联邦通信委员会(FCC)规定。 [0004] Meanwhile, (capacitive) sensor may be used for neighborhood having built-in wireless wide area network (WW) (such as a third or fourth generation (3G / 4G) digital radio) is transmitted to the tablet, such as a specific absorption rate ( SAR) this Federal communications Commission (FCC) regulations. 例如,邻域传感器可以检测邻域内的人体,并且可以使用具有相对大尺寸的传感器电极来实现邻域检测。 For example, sensors can detect a human body neighborhood of the neighborhood, and the sensor electrode may be used having a relatively large size to achieve the neighborhood detection. 由于NFC和邻域传感器设备都会要求便携式设备中的显著空间,且任一者都不会被金属底盘/遮罩所覆盖。 Because NFC sensor device and the neighborhood will require a significant space in the portable device, and any of which will not be covered by a metal chassis / mask. 换言之,NFC和邻域传感器设备会为了无线设备(例如平板电脑)上的天线的非常有限的空间而竞争。 In other words, NFC sensor device and the neighborhood to be a wireless device (e.g., tablet) on a very limited space of the antenna compete. 随着便携式设备变得更薄且采取完全金属底盘,有限空间将变得更有挑战性。 As portable devices become thinner and take a completely metal chassis, the limited space becomes more challenging. 为此,当NFC和/或邻域传感器为了适配于薄型便携式设备内而使它们相应的尺寸变得更为紧凑时,它们的性能会受到损害。 For this reason, when the NFC and / or neighborhood to fit within the sensor device so that their respective thin portable size becomes more compact, their performance may be impaired. 因而,可以实现解决方案来提供与薄型便携式设备中的邻域传感器和NFC设备的性能有关的效率。 Accordingly, it is possible to implement a solution properties provide the NFC device and the neighborhood of the sensor thin portable device efficiency.

[0034] 图3是具有无源器件的邻域传感器和NFC模块的示例实现300。 [0034] FIG. 3 is an exemplary neighborhood of the sensor and the NFC module 300 implemented with passive devices. 与近场耦合相关的新兴技术使便携式设备102的用户能有许多吸引人的体验。 Emerging technologies related to the near-field coupling of the portable user device 102 can have a number of attractive experience. 例如,将柔性印刷电路(FPC)——该柔性印刷电路(FPC)结合NFC/传感器环形天线204——集成到薄型便携式设备102中可以使便携式设备102的厚度的任何增量最小化。 For example, a flexible printed circuit (FPC) - the flexible printed circuit (FPC) binding NFC / sensor loop antenna 204-- integrated into any increment thin portable device 102 can cause the thickness of the portable device 102 is minimized.

[0035] 继续参考图3,该图示出被集成到单个模块(即,邻域传感器电路和NFC模块联合体206)中的邻域传感器302和NFC模块304。 [0035] With continued reference to FIG. 3, there is shown integrated into a single module (i.e., the neighborhood and the NFC module consortium sensor circuit 206) in the neighborhood of the sensor 302 and the NFC module 304. 在一实现中,邻域传感器302可以被配置成使用NFC/传感器环形天线204来携带邻域感测电信号。 In one implementation, the neighbor sensor 302 may be configured to use the NFC / sensor loop antenna 204 to carry the electrical signals sensed neighborhood. 尽管NFC/传感器环形天线204可由NFC模块同时使用以用于NFC相关的功能,可以通过安装无源器件来将邻域感测电信号与NFC电信号分隔开。 Although the NFC / sensor loop antenna 204 may be used simultaneously for the NFC module NFC related functions, the neighborhood can be sensed electrical signals and the electrical signals are separated by NFC mounting passive devices.

[0036] 在一实现中,邻域传感器302可以被配置成以诸如30KHz电信号的低频电信号进行操作以用于邻域感测操作。 [0036] In one implementation, the neighbor sensor 302 may be configured as an electric signal to a low frequency electrical signal operates to 30KHz neighborhood for sensing operation. 在该例中,通过评估被注入环形天线204的充电和放电电流来测量电容性特征。 In this embodiment, the loop antenna is injected into the charge and discharge current 204 is measured by evaluating the capacitive characteristics. 当人进入到NFC/传感器环形天线204的邻域时,电容性特征可以变化。 When a person enters the NFC / sensor loop antenna neighborhood 204, the capacitor characteristics may vary. 电容性特征的变化可以与触发TX/RX天线200的选择的已配置电容变化阈值相比较,或者降低无线通信电路208的TX功率。 Variation in capacitance characteristics may be selected to trigger the TX / RX antenna 200 configured capacitance change compared to a threshold, or a wireless communication circuit 208 to reduce the TX power. 该阈值可以类似地应用于由于NFC/传感器环形天线204邻域内的另一便携式设备的金属组件而造成的电容性特征的变化。 The threshold may be similarly applied to a change in capacitance characteristics due to the metal components of the portable device to another NFC / sensor loop antenna 204 caused by neighborhood.

[0037] 在一实现中,NFC/传感器环形天线204可以被配置成在邻域感测操作期间包括开端形状。 [0037] In one implementation, NFC / sensor loop antenna 204 may be configured to include the beginning of the neighborhood shape during a sensing operation. 例如,与NFC/传感器环形天线204的一端相连的终端链路306-2可以被连接至邻域传感器302,并且连接至NFC模块304的前端的端子。 For example, with a terminal end NFC / sensor 204 connected to the loop antenna 306-2 may be connected to link neighborhood sensor 302, and a front end connected to a terminal 304 of the NFC module. 与NFC/传感器环形天线204的另一端相连的第二终端链路306-4可以被连接至NFC模块304的另一端子。 The other end of the second terminal NFC / sensor 204 connected to the loop antenna 306-4 may be connected to link the NFC module 304 of another terminal. 在一实现中,NFC模块304的前端端子连接至电容器308,电容器308将NFC模块304链接至NFC/传感器环形天线204的终端连接306。 In one implementation, the NFC module 304 of the front end of the terminal connected to the capacitor 308, the capacitor 308 linked to terminal 304 the NFC module NFC / sensor 204 connected to the loop antenna 306. 在邻域感测操作期间,电容器308 (例如470pF)可以充当对低频电信号(例如30KHz)的开路(即,高度隔离)。 During the sensing operation neighborhood, a capacitor 308 (e.g. 470pF) may act as an open circuit to low frequency electrical signal (e.g. 30KHz) (i.e., high isolation). 换言之,终端连接306-2和306-4与NFC模块304的前端断开。 In other words, terminals 306-2 and 306-4 are connected with the front end 304 of the NFC module is disconnected. 另一方面,包括无源器件电阻器310的低通滤波器可以充当对30KHz邻域感测电信号的短路(即,低衰减)。 On the other hand, resistance of the device includes a passive low-pass filter 310 may act as a short circuit for sensing an electrical signal 30KHz neighborhood (i.e., low attenuation). 因而,对于邻域感测操作,NFC/传感器环形天线204对于低频邻域感测信号来说呈现为开端螺旋形NFC/传感器环形天线204。 Thus, the sensing operation for the neighbor, NFC / sensor loop antenna 204 for the low frequency signals for the neighborhood presented as a sensing start helical NFC / sensor loop antenna 204.

[0038] 在NFC操作期间,电容器308可以包括在相对高工作频率(例如,对于NFC操作的13.56MHz)处等价的短路。 [0038] NFC During operation, the capacitor 308 may comprise a relatively high frequency (e.g., for NFC operation of 13.56 MHz) at the equivalent short-circuit. 另一方面,将NFC/传感器环形天线204链接至邻域传感器302的低通滤波器可以提供在13.56MHz的NFC操作频率下等价的开路。 On the other hand, the NFC / sensor loop antenna 204 linked to a neighboring sensor lowpass filter 302 may be provided at equivalent operating frequency of 13.56MHz NFC open. 换言之,在NFC操作期间,将邻域传感器302链接至NFC/传感器环形天线204的低通滤波器可以隔离高频NFC电信号。 In other words, the NFC during operation, the sensor 302 is linked to the neighborhood NFC / sensor loop antenna 204 may be a low pass filter NFC isolate high frequency electrical signals. 因而,对于NFC操作,NFC/传感器环形天线204对于高频NFC信号来说呈现为闭合螺旋形NFC/传感器环形天线204。 Thus, the operation for the NFC, NFC / sensor loop antenna 204 for high frequency signals, NFC exhibits a closed helical NFC / sensor loop antenna 204.

[0041] 在一实现中,开关402可以基于便携式设备102处的使用被动态地控制。 [0041] In one implementation, switch 402 may be dynamically controlled based on the use of the portable device 102. 例如,如果TX/RX天线200不被使用(例如,用于3G传输),则NFC/传感器环形天线204可以专门主要用于NFC相关的功能。 For example, if the TX / RX antenna 200 is not used (e.g., for transmission 3G), then the NFC / sensor loop antenna 204 may be used primarily dedicated NFC related functions. 与无源器件的使用(即,电容器308和电阻器310)相比,无源器件(即,开关402)可以被配置成在时域中在特定时刻执行邻域感测检测和在另一时刻执行NFC相关的功能之间来回切换。 And the use of passive components (i.e., the capacitor 308 and resistor 310) as compared to passive devices (i.e., switch 402) may be configured to perform neighborhood sensing detector and at another time at a given moment in the time domain NFC is performed back and forth between related functions.
