Abstract

The invention discloses a mixed-type near-field communication (NFC) antenna and a fabrication method thereof. The mixed-type NFC antenna comprises an ultrathin antenna and a secondary antenna, wherein the ultrathin antenna comprises a first polymer thin sheet and an antenna radiator; the antenna radiator is printed on the first polymer thin sheet, and comprises an antenna port; the secondary antenna comprises a second polymer thin sheet and an antenna feeder; the antenna feeder is printed on the second polymer thin sheet; the secondary antenna is located above the antenna radiator; one end of the antenna feeder is connected with the antenna port; the other end of the antenna feeder is connected to a mobile phone mainboard; and the secondary antenna and the ultrathin antenna are jointed with the connected part of the antenna feeder and the antenna port. According to the mixed-type NFC antenna, the overall thickness of the antenna can be reduced under the premise that the radio-frequency performance is ensured; the mixed-type NFC antenna can be suitable for the requirements of the structural design of an ultrathin mobile phone; the manufacturing cost of the antenna is low; and by an aluminum printed circuit, compared with an existing flexible printed circuit board (FPCB) paved with copper on double surfaces, the cost is reduced by 30%.

Description

technical field [0001] The invention relates to the field of antennas, in particular to an NFC antenna and a manufacturing method. Background technique [0002] NFC (Near Field Communication) antennas have been extensively researched and applied along with the development of mobile payment functions. NFC antennas specially used for mobile payment functions have proposed a variety of antenna models at home and abroad, which are applied to different styles and types of mobile phones and different performance indicators. However, with the development of mobile phones in a thinner direction, higher requirements are placed on the structure of the NFC antenna. The traditional NFC antenna is composed of double-sided copper-coated FPCB (flexible circuit board) + Ferrite (ferrite). The overall thickness of the antenna is generally above 0.37mm, which has gradually failed to meet the overall slim requirements of mobile phones. Contents of the invention [0003] In order to solve t...
