摘  要:NFC 是一种近距离识别技术,在当前市面上使用极其广泛,NFC 方案多采用NFC 模块集成NFC 差分天线的设计方式。而对于新应用场景,如餐饮智能柜,要求在智能柜可以实时监测柜中各个位置是否存在粘贴NFC 标签的物品。如果采用传统NFC 设计方式,需要采用多个NFC 识别模块,造成整体方案的成本急剧上升。本文中提出了一种采用一台NFC 设备搭载多路NFC 天线的高性能匹配设计方案。

Abstract:NFC is a close-range identification technology,which is widely used in the current market. The NFC scheme mostlyuses NFC module to integrate the design of NFC differential antenna. For new application scenarios,such as restaurant smart cabinet,it is required that the smart cabinet can real-time monitor whether there are items pasted with NFC labels in each location of the cabinet.If the traditional NFC design is adopted,multiple NFC recognition modules are needed,resulting in a sharp increase in the cost of theoverall scheme. In this paper,a high-performance matching design scheme for a multi-channel NFC antenna mounted on a single NFCdevice is proposed.

Keywords:NFC;single-ended NFC;multiple NFC antenna
