Example Embodiment

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

[0021] Reference Figure 1 to Figure 3 As shown, the present invention provides a near field communication antenna device using a metal shell terminal device, which includes: a metal shell 1 and a magnetic conductive material 4 arranged below the inside of the metal shell 1. Below the magnetically conductive material 4 is an electronic device 5. The metal shell is provided with a slit band, the slit has and only one end extends to the edge of the metal shell, and the metal shell 1 is connected to a matching circuit as a radio frequency radiator. In order to ensure that the metal casing 1 as a near field communication radiator will not affect other antennas of the mobile phone, the edge of the metal casing 1 can be grounded.

[0022] Among them, the metal casing 1 can be made of common aluminum processing or metal electroplating. The metal casing 1 is provided...

Abstract

The invention discloses a near-field communication antenna device adopting a metal shell terminal device, comprising: a metal shell and a magnetically conductive material arranged below the inside of the metal shell; the metal shell is provided with a gap band, and the gap band includes two parts One part is a closed or unclosed slot of any shape arranged in the metal shell, and the other part is a long slot connecting the slot of any shape and the edge of the metal shell, and the slot is filled with a non-conductive material. The metal casing is connected to a matching circuit as a radio frequency radiator, and the edge of the metal casing is grounded. The present invention realizes the antenna function of the metal shell through the gap zone on the surface of the metal shell, and the non-conductive material in the gap zone realizes the integral molding of the metal shell, avoids the difficulty of installation and configuration caused by additionally designing the antenna plug-in, and reduces the movement The thickness of the equipment and the difficulty of assembly completely eliminate the shielding effect of the traditional metal shell on the antenna, and the performance is excellent.

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...
