Abstract

The invention provides a near field communication (NFC) and wireless charging integrated antenna device, an antenna module supporting multiplexing of NFC and wireless charging and an application thereof of an NFC and wireless charging integrated system. The NFC and wireless charging integrated antenna device comprises an antenna coil, wherein a wireless charging feeding point and an NFC and wireless charging shared feeding point are respectively arranged at two ends of the antenna coil in an extension way, an NFC feeding point is arranged at a middle part of the antenna coil in an extension way, a part, arranged between the NFC feeding point and the NFC and wireless charging shared feeding point, of the antenna coil is an NFC coil part, and a part, arranged between the wireless charging feeding point and the NFC and wireless charging shared feeding point, of the antenna coil is a wireless charging coil part. The NFC and wireless charging integrated antenna device has the following advantages that no extra NFC antenna is needed, the cost is reduced, the antenna space occupancy area becomes small, and the space utilization ratio becomes high.

Description

technical field [0001] The present invention relates to the field of NFC (Near Field Communication) and wireless charging antenna design, in particular to an NFC and wireless charging two-in-one antenna device, an antenna module supporting NFC and wireless charging multiplexing, and an NFC and wireless charging two-in-one system usage method. Background technique [0002] At present, mobile terminals are being used more and more widely, and the functions of the terminals are already very powerful, full of rich entertainment, such as listening to music, watching TV, surfing the Internet and so on. In the process of using the mobile terminal, due to the limitation of the battery capacity, people find that the power of the battery is used up soon, and the battery often needs to be charged. The emergence of wireless charging technology represented by electromagnetic induction has brought convenience to consumers. The wireless charging device can conveniently charge the mobile ...
