Description
本發明涉及一種天線及具有該天線的電子產品，尤其涉及一種射頻識別天線及具有該射頻識別天線的電子產品。 The present invention relates to an antenna and an electronic product having the same, and more particularly to an RFID antenna and an electronic product having the same.
藍芽(BlueTooth)是一種支援電子設備短距離通信的無線電技術，該技術現已應用於移動電話、PDA、MP3、藍芽耳機、筆記型電腦等眾多電子產品上，且該等電子產品內部設置有藍芽天線，從而使得該等電子產品之間可以進行無線資訊交換。 Bluetooth (BlueTooth) is a radio technology that supports short-range communication of electronic devices. It is now applied to many electronic products such as mobile phones, PDAs, MP3s, Bluetooth headsets, notebook computers, etc., and the internal settings of these electronic products. There are Bluetooth antennas that allow wireless information exchange between these electronic products.
如今，市場上銷售有許多是仿造、假冒的電子產品，它們的形狀外觀與正規廠家生產的產品一樣，但是產品的功能和質量卻有瑕疵，無法得到保障，而消費者卻無法識別，容易上當受騙。 Nowadays, there are many counterfeit and counterfeit electronic products on the market. Their shapes and appearances are the same as those produced by regular manufacturers. However, the functions and quality of the products are flawed and cannot be guaranteed, but consumers are not recognized and easy to be fooled. Being cheated.
為了解決上述問題，出現了一種射頻識別技術(RFID)。射頻識別技術通過射頻訊號自動識別目標對象並獲取相關數據。射頻識別技術系統的組成部分一般包括標籤(Tag)、閱讀器(Reader)及傳遞標籤與閱讀器之間射頻訊號的射頻識別天線。標籤由耦合元件及芯片組成，每個標籤具有唯一的電子編碼，附著在物體表面上標識目標對象，閱讀器用來讀取標籤訊息。當標籤進入磁場後，接受閱讀器發出的射頻訊號，並由射頻識別天線發送出存儲在芯片中的產品訊息，消費者就可以由此而辨別產品真假。 In order to solve the above problem, a radio frequency identification (RFID) technology has emerged. Radio frequency identification technology automatically identifies target objects and acquires relevant data through RF signals. The components of the RFID system generally include a tag, a reader, and an RFID antenna that transmits an RF signal between the tag and the reader. The tag consists of a coupling element and a chip. Each tag has a unique electronic code attached to the surface of the object to identify the target object, and the reader is used to read the tag information. When the tag enters the magnetic field, it receives the RF signal from the reader, and the RFID antenna sends out the product information stored in the chip, so that the consumer can distinguish the product from the true and false.
然而，習知射頻識別天線擺設佔用空間大，從而在 電子產品中容易與其它元件(如藍芽天線)發生相互干擾，且訊號輻射強度弱，需要讓閱讀器平貼在標籤上才能讀到標籤中芯片上的產品訊息。 However, the conventional RFID antenna occupies a large space and thus Electronic products easily interfere with other components (such as Bluetooth antennas), and the signal radiation intensity is weak. The reader needs to be flat on the label to read the product information on the chip in the label.
