Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] refer to Figure 1 to Figure 3 As shown, the present invention provides a near-field communication antenna device using a metal shell terminal device, including: a metal shell 1 and a magnetically permeable material 4 disposed under the metal shell 1 . Below the magnetically permeable material 4 is an electronic device 5 . The metal casing is provided with a slot belt, and only one end of the slot extends to the edge of the metal casing. The metal casing 1 is connected to a matching circuit as a radio frequency radiator. In order to ensure that the metal case 1 as a near-field communication radiator will not affect other antennas of the mobile phone, grounding treatment can be performed on the edge of the metal case 1 .

[0022] Wherein, the metal shell 1 can be made by common aluminum processing or metal plating. The metal casing 1...

Abstract

The invention discloses a near field communication antenna device adopting metal shell terminal equipment. The device comprises a metal shell and magnetic material arranged at the lower side of the metal shell. A seam belt is formed in the metal shell, and comprises two parts, one part is a random shape seam belt which is either closed or non-closed arranged in the metal shell, the other part is a long strip seam belt connected with the random shape seam belt and the metal shell edges. The seam belts are filled with dielectric material. The metal shell is connected with a matching circuit as a radio frequency radiation body. The edges of the metal shell are grounded. According to the near field communication antenna device adopting metal shell terminal equipment, the metal shell antenna function is achieved through a seam belt in the metal shell surface, the dielectric material in the seam belt achieves the integral forming of the metal shell and avoids the installation and configuration difficulties brought by the additional arrangement of antenna plug-in parts, the shielding function of the metal shell to the antenna is completely eliminated, and the device has a good performance.

Description

technical field [0001] The invention relates to the communication field, in particular to a near-field communication antenna device using a metal shell terminal device. Background technique [0002] RFID (Radio Frequency Identification) or NFC (Near Field Communication) technology that communicates with external devices through electromagnetic field signals has gradually become popular. In order to communicate between the mobile electronic equipment or the mobile electronic equipment and the basic card reading equipment, each equipment, especially the handheld mobile electronic equipment, is equipped with a communication antenna device and assembled inside the mobile equipment shell. [0003] With the popularity of mobile communication devices with metal back covers, the service life of mobile electronic devices and the wear resistance of the device casing have been greatly improved, providing customers with a better experience. Recently, with the popularity of consumers, m...
