Abstract

The embodiment of the invention discloses an NFC antenna, the NFC antenna is arranged in electronic equipment, the electronic equipment comprises a cellular antenna, the NFC antenna comprises an NFC chip, a port of a first differential signal of the NFC chip is connected with a first connection point of a radiator of the cellular antenna, a port of a second differential signal of the NFC chip is connected with a second connection point of the radiator of the cellular antenna, and the first connection point is connected with the first connection point of the radiator of the cellular antenna. And a conductive path formed by the radiator part between the first connection point and the second connection point is used for transmitting differential excitation current generated by the NFC chip. The invention further provides an electronic device.

Description

technical field [0001] The present application relates to the technical field of sharing a near field communication (Near Field Communication, NFC) antenna and a cellular antenna, and in particular relates to an NFC antenna and an electronic device. Background technique [0002] At present, in a mobile phone terminal, the NFC antenna is generally made on the pressure plate bracket in the form of ferrite + flexible printed circuit (Flexible Printed Circuit, FPC) coil. Due to the introduction of the 5th Generation Mobile Communication Technology (5G) antenna and the Ultra Wide Band (UWB) antenna, the space of the pressure plate support is further compressed, and it is difficult to design the NFC antenna on the pressure plate support. Therefore, the multiplexing of NFC antennas and metal frame antennas has become a technical development trend. [0003] However, in the related art, when the NFC antenna and the cellular antenna are shared, the ground plane will be introduced. Fo...
