一种用于近距离无线通讯的天线及移动终端Antenna and mobile terminal for short-distance wireless communication

技术领域technical field

本实用新型涉及通信领域，具体涉及一种用于近距离无线通讯的天线及移动终端。The utility model relates to the communication field, in particular to an antenna and a mobile terminal for short-distance wireless communication.

背景技术Background technique

近场通信(Near Field Communication，NFC)，又称近距离无线通信，是一种短距离的高频无线通信技术，允许电子设备之间进行非接触式点对点数据传输(在十厘米内)交换数据。这个技术由免接触式射频识别(RFID)演变而来，并向下兼容RFID，因此可以在移动设备、消费类电子产品、PC和智能控件工具间进行近距离无线通信，可以让消费者简单直观地交换信息、访问内容与服务。由于近场通讯具有天然的安全性，因此，NFC技术被认为在手机支付等领域具有很大的应用前景。Near Field Communication (NFC), also known as short-range wireless communication, is a short-range high-frequency wireless communication technology that allows non-contact point-to-point data transmission (within ten centimeters) between electronic devices to exchange data . This technology evolved from contactless radio frequency identification (RFID) and is backward compatible with RFID, so it can perform short-range wireless communication between mobile devices, consumer electronics, PCs and smart control tools, allowing consumers to simply and intuitively Exchange information, access content and services efficiently. Due to the natural security of near-field communication, NFC technology is considered to have great application prospects in fields such as mobile payment.

在现有方案与技术中，NFC天线常常采用独立FPC(柔性电路板)的形式来进行实现。例如，在FPC上走线，然后将FPC和走线一起粘贴在液晶显示屏上。这种方式的缺点很明显，势必需要单独的FPC组件来实现，同时，在组装生产时也需要增加工位来实现，一定程度上有损组装效率。In existing solutions and technologies, the NFC antenna is often implemented in the form of an independent FPC (flexible printed circuit board). For example, trace the wires on the FPC, and then paste the FPC and the wires together on the LCD screen. The disadvantage of this method is obvious, and it is bound to require a separate FPC component to realize it. At the same time, it also needs to increase the number of stations to realize it during assembly production, which will damage the assembly efficiency to a certain extent.

在现有方案与技术中，NFC天线也有采用导电透明膜而实现的NFC天线的形式。例如，使用一导电透明薄膜贴附在显示屏幕上，所述薄膜内部设置有一天线和NFC芯片。目前这种工艺和材料还不足以实现这种应用，这在一定程度上影响了这种方案的推广与应用，更重要的是，这种方式的加工成本较高。In existing solutions and technologies, the NFC antenna also has the form of an NFC antenna realized by using a conductive transparent film. For example, a conductive transparent film is attached to the display screen, and an antenna and an NFC chip are arranged inside the film. At present, this technology and materials are not enough to realize this application, which affects the promotion and application of this solution to a certain extent, and more importantly, the processing cost of this method is relatively high.

另外，不论是以前上哪种方案，都需要增加独立的附加组件来协助完成，如柔性电路板或导电薄膜，这就不可避免的造成成本的增加。In addition, regardless of the previous solution, it is necessary to add an independent additional component to assist in the completion, such as a flexible circuit board or a conductive film, which inevitably leads to an increase in cost.
