Description
本發明提供一種近場天線模組，且特別是關於一種不需要鐵氧體(ferrite)的近場天線模組及其傳輸裝置。 The present invention provides a near field antenna module, and more particularly to a near field antenna module that does not require ferrite and a transmission device thereof.
近場通訊(Near Field Communication，NFC，又稱近距離無線通訊)係由免接觸式射頻識別(RFID)演變而來。近場通訊是一種短距離的高頻無線通訊技術，其允許相距十公分(3.9英吋)內的兩電子裝置之間進行非接觸式點對點資料傳輸。近場通訊需要兩電子裝置之間能夠產生近場感應，才可使兩電子裝置能夠彼此進行資料傳輸。 Near Field Communication (NFC), also known as Near Field Communication (RFID), evolved from contactless radio frequency identification (RFID). Near Field Communication is a short-range, high-frequency wireless communication technology that allows non-contact point-to-point data transmission between two electronic devices within ten centimeters (3.9 inches). Near-field communication requires near-field sensing between two electronic devices to enable two electronic devices to transmit data to each other.
另外，無線充電(又稱作感應充電、非接觸式感應充電)是利用近場感應，也就是電感耦合，使得供電裝置(例如，充電器)可將能量傳送至用電的電子裝置。電子裝置接著使用接收到的能量對電池充電，並同時供其本身運作之用。由於充電器與用電的電子裝置之間以電感耦合傳送能量，兩者之間不用電線連接，因此充電器及用電的電子裝置都可以做到無導電接點外露。 In addition, wireless charging (also known as inductive charging, non-contact inductive charging) utilizes near-field sensing, that is, inductive coupling, such that a power supply (eg, a charger) can transfer energy to a powered electronic device. The electronic device then uses the received energy to charge the battery and simultaneously for its own operation. Since the charger and the powered electronic device transmit energy by inductive coupling, the wires are not connected between the two, so the charger and the powered electronic device can be exposed without conductive contacts.
現在，有許多的可攜式電子裝置會支援無線充電與近場通訊的功能。由於無線充電與近場通訊需要產生近場感應，因此，所述可攜式電子裝置需要設置有近場天線模組。目前的近場天線模組需要設置有鐵氧體(ferrite)，以增加其電磁通量，從而補償其他元件對其電磁通量所造成的衰減。然而，鐵氧體的成本較高，將導致近場天線模組之成本的增加。 Today, there are many portable electronic devices that support wireless charging and near field communication. Since the wireless charging and the near field communication need to generate near field sensing, the portable electronic device needs to be provided with a near field antenna module. Current near-field antenna modules need to be provided with ferrite to increase their electromagnetic flux to compensate for the attenuation of other components' electromagnetic flux. However, the higher cost of ferrite will result in an increase in the cost of the near field antenna module.
本發明實施例在於提供一種近場天線模組，所述近場天線模組包括主要輻射體、第一次要輻射體與第二次要輻射體。主要輻射體用以產生第一電磁場。第一次要輻射體用以產生第二電磁場，以增加第一電磁場的電磁通量。第二次要輻射體用以產生第三電磁場，以增加第一電磁場的電磁通量。第一至第三電磁場彼此疊加而形成感應區，且感應區位於近場天線模組的外側。 An embodiment of the present invention provides a near field antenna module, where the near field antenna module includes a primary radiator, a first secondary radiator, and a second secondary radiator. The primary radiator is used to generate a first electromagnetic field. The first time the radiator is used to generate a second electromagnetic field to increase the electromagnetic flux of the first electromagnetic field. The second radiator is used to generate a third electromagnetic field to increase the electromagnetic flux of the first electromagnetic field. The first to third electromagnetic fields are superposed on each other to form a sensing area, and the sensing area is located outside the near field antenna module.
