Passive-signal enhancement antenna sheet for iphone full-card NFC scheme

Abstract

The invention provides a passive-signal enhancement antenna sheet for an iphone full-card NFC scheme. An antenna is in the form of a sheet when unfolded. According to the passive-signal enhancement antenna sheet, a flexible circuit board and the antenna with metal additionally arranged on an equivalent flexible substrate or the antenna with a wound fine metal wire are adopted. The antenna comprises a small-sized spiral coil and a large-sized spiral coil which are connected in series. The shape of the small-sized spiral coil is similar to a rectangle. The size of the small-sized spiral coil is identical to the size of the portion, on the side surface of an iphone, of an iphone card support, and the small-sized spiral coil is arranged outside the card support of a SIM card on the side surface of the iphone. The large-sized coil is folded to the back surface of the iphone. The size of the large-sized coil is not larger than the size of the back surface of the iphone. By the adoption of the passive-signal enhancement antenna sheet for the iphone full-card NFC scheme, the defect that it is difficult for a reader to receive sent signals of the SIM card of the iphone is overcome, the shape of the SIM card and the universality of the iphone are not changed, and the communication mode with durability and high robustness is also achieved.

Description

technical field [0001] The invention relates to a dual-frequency communication antenna, in particular to a passive signal enhancement antenna post for Apple's full card NFC scheme, and a passive antenna for mobile payment mobile phone SIM card signal enhancement.
