Problems solved by technology

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.

Abstract

The invention discloses a hybrid NFC antenna and a manufacturing method. The hybrid NFC antenna includes an ultra-thin antenna and a sub-antenna; the ultra-thin antenna includes a first polymer sheet and an antenna radiator printed on it; the antenna radiator includes an antenna port The auxiliary antenna includes a second polymer sheet and an antenna feeder printed on it; the auxiliary antenna is located above the antenna radiator, one end of the antenna feeder is connected to the antenna port, and the other end is connected to the main board of the mobile phone, and the auxiliary antenna and the ultra-thin antenna are connected to the antenna The connection between the feeder and the antenna port. The invention can reduce the overall thickness of the antenna under the premise of ensuring the radio frequency performance, and is more suitable for the structural design requirements of ultra-thin mobile phones, and the antenna is made less, and the aluminum printed circuit is used, which is better than the existing double-sided copper coating The cost of FPCB is 30% lower.

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...
