Description
本發明是有關於一種天線結構，特別是指金屬板開有隙縫的天線結構。 The present invention relates to an antenna structure, and more particularly to an antenna structure in which a metal plate has a slit.
近場通訊(Near Field Communication,NFC)是一種短距離的高頻無線通訊技術，其主要特色是令各電子設備之間在短距離間快速地進行非接觸式點對點資料傳輸。由於具有近場通訊晶片之裝置不需經由接觸即可相互感應，因此當近場通訊技術應用於行動商務，電子商務，以及身分識別等具有相當的優勢。而隨著行動電話的逐漸普及，目前已有近場通訊技術應用於行動電話中，以增添消費者於生活上的便利性，舉例來說，一具有一近場通訊晶片卡之行動電話可利用該近場通訊晶片卡作為電子錢包以購買商品，或者利用該近場通訊晶片卡作為身分識別證件。如此，當消費者出門時只需帶著行動電話，而不需另外攜帶錢包和證件外出。 Near Field Communication (NFC) is a short-range high-frequency wireless communication technology. Its main feature is to enable non-contact point-to-point data transmission between short distances between electronic devices. Since devices with near-field communication chips can sense each other without contact, the application of near-field communication technology to mobile commerce, e-commerce, and identity recognition has considerable advantages. With the gradual popularization of mobile phones, near-field communication technology has been applied to mobile phones to increase the convenience of consumers in life. For example, a mobile phone with a near field communication chip card can be utilized. The near field communication chip card is used as an electronic wallet to purchase goods, or the near field communication chip card is used as an identity identification document. In this way, when the consumer goes out, they only need to take a mobile phone without having to carry a wallet and documents to go out.
然而，現今近場通訊技術的各種應用中，由於載具與感應裝置間的感應距離有一定的限制，因此常發生使用者須將載具緊貼於感應裝置來進行感應作業，如此造成諸多使用上的不便，且近場通訊若應用於含有金屬外殼之載具，則金屬外殼會遮蔽近場通訊用於傳遞訊號與能量之磁場，使得載具與感應裝置間的感應距離降低。有鑒於此，本發明人乃潛心研究並配合學理的運用，而提出一種設計合理且有效改善上述問題的本發明。 However, in various applications of the near field communication technology, since the sensing distance between the carrier and the sensing device is limited, it is often the case that the user has to attach the carrier to the sensing device to perform the sensing operation, thus causing many uses. Inconvenience, and if the near field communication is applied to a carrier containing a metal casing, the metal casing shields the near field communication for transmitting the magnetic field of the signal and the energy, so that the sensing distance between the carrier and the sensing device is reduced. In view of the above, the present inventors have devoted themselves to research and cooperate with the application of the theory, and have proposed a present invention which is reasonable in design and effective in improving the above problems.

進一步地說，隙縫可以設置有一絕緣物，以連接第一金屬板區域及第二金屬板區域。金屬板設置於線圈單元的一側，且金屬板的隙縫可以裸露至少三分之一的線圈開口。隙縫的兩端開口可以是分別設置於金屬板的相異兩側邊或是相同的側邊上；舉例來說，金屬板可以是包含一第一短邊、一第二短邊、一第一長邊及一第二長邊的矩形板體，隙縫的一端開口可以是設置於第一短邊、第二短邊、第一長邊及第二長邊的其中之一，而隙縫的另一端開口則可以是設置於第一短邊、第二短邊、第一長邊及第二長邊的其中之一。線圈單元的電流方向與金屬板的第一金屬板區域及第二金屬板區域的感應電流方向相同。 Further, the slit may be provided with an insulator to connect the first metal plate region and the second metal plate region. The metal plate is disposed on one side of the coil unit, and the slit of the metal plate can expose at least one third of the coil opening. The two ends of the slit may be respectively disposed on different sides or the same side of the metal plate; for example, the metal plate may include a first short side, a second short side, and a first a rectangular plate body having a long side and a second long side, wherein one end opening of the slit may be disposed on one of the first short side, the second short side, the first long side and the second long side, and the other end of the slit The opening may be one of the first short side, the second short side, the first long side and the second long side.

As shown in FIG. 2, when the metal plate 10 is placed over the coil unit 20, the slit 11 of the metal plate 10 exposes at least a portion of the coil opening 201 of the coil unit 20.
