WIPO Patent Application WO/2021/093545
Kind Code:
A1
Abstract:
The present application provides an antenna and a mobile terminal, the antenna is an NFC antenna, and the antenna is applied to the mobile terminal, in specific settings, the antenna comprises: a feed line, a radiator and a ground line; wherein, the radiator is an annular radiator with an opening, and the ends of the radiator located on the two sides of the opening are respectively a feed point and a ground point; the distance between the ground point and the feed point is at least not less than a set value; and the feed point is connected with the feed point, and the ground point is connected with the ground wire. In the above technical scheme, the NFC antenna is separately arranged in the mobile terminal, thereby realizing the decoupling with other non-NFC antennas; in addition, the NFC antenna is arranged in a mode that a single-ended feed is adopted, and the other end of the NFC antenna is grounded, so that the single-ended NFC performance is realized in a very small clearance environment, and compared with the prior art, the dual-ended NFC antenna is low in cost and small in area.
