Embodiment Construction

[0026] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0027] The purpose of the present invention is to use the form of main and auxiliary antennas and the principle of radio frequency coupling communication without physically connecting the pads and antennas of the module through complicated welding processes, simplifying the production process of non-contact smart cards and increasing product reliability. , and effectively reduce costs and improve production efficiency.

[0028] For low-frequency and high-frequency contactless smart cards, the main antenna of the RF coupling amplifying antenna is composed of a series resonant circuit composed of a group of one-turn or multi-turn inductive antennas and at least one capacitor, and its communication frequency is between 100KHz and 100MHz. like Fig...

Abstract

The invention discloses a novel non-contact intelligent card which consists of an independent miniature radio frequency module, a plane membrane radio frequency coupling amplification antenna with a miniature module mounting hole, a closed upper outer layer card base, an upper inner layer card base with a mounting hole, a closed lower outer layer card base, and a lower inner layer card base with a mounting hole; a radio frequency coupling antenna amplifies and transfers a signal of the miniature radio frequency module to realize normal non-contact communication of the miniature radio frequency module, the reliability of a product is enhance and the production cost of the product is reduced.

Description

technical field [0001] The invention relates to the field of radio frequency communication, in particular to the field of non-contact smart cards, in particular to a manufacturing method of a novel non-contact smart card, which can be widely used in the fields of non-contact smart cards and electronic labels. Background technique [0002] The application of wireless radio frequency communication technology has been widely used in today's society, and radio frequency communication has become an indispensable part of our life. A large number of applications of contactless smart cards and electronic tags based on radio frequency communication technology have made people's lives more convenient and made social development a big step forward. The 13.56MHz high-frequency (HF) frequency band near-field payment method has been widely used in many fields such as transportation, access control, logistics, and identity management. The fact that the traffic card, access control card, a...
