Description
Technical Field
The invention belongs to the field of NFC antenna design, and particularly relates to handheld electronic equipment with a sling mount as an NFC antenna.
Background
Existing portable handheld electronic devices, such as PDAs (Personal Digital assistants), typically have NFC (Near Field Communication) functionality. Specifically, the portable handheld electronic device realizes the NFC function based on the NFC component, the NFC component is composed of an NFC module and an NFC antenna, the NFC module is located on the motherboard, and the NFC antenna is usually disposed on the inner side of the battery cover and electrically connected to the NFC module.
However, when the portable handheld electronic device is to communicate with an external NFC card reader, the alternating electromagnetic field induced by the NFC antenna under the action of the excitation signal emitted by the NFC card reader is easily subjected to the eddy current attenuation effect of the metal component in the portable handheld electronic device, so that the signal strength of the alternating electromagnetic field is greatly reduced, which may possibly result in the failure of the NFC card reader in reading. For the problem, the existing solution is to add a ferrite shielding magnetic sheet to isolate the absorption of the metal material to the antenna magnetic field, increase the magnetic field strength of the antenna, and thus effectively increase the communication induction distance. However, the provision of ferrite shielding magnetic sheets tends to result in an increase in the number of process steps in the manufacturing process of portable handheld electronic devices.
In the related art, a portable handheld electronic device has an NFC function and also adopts a structural design of a strap buckle. Specifically, the strap buckle is disposed on the rear housing of the portable handheld electronic device and is used in cooperation with a matched strap or wristband to meet the corresponding carrying requirements of the user.
