Embodiment Construction

[0026] The present invention will be described in further detail below with reference to the accompanying drawings.

[0027] The manufacturing method of the electronic license plate of the present invention, as shown in Fig. 1, includes the following steps:

[0028] 1. Punch grooves on the license plate body shown in Figures 1a and 1b, where Figure 1a is a schematic diagram of the front of the license plate body, and Figure 1b is a schematic diagram of the side of the license plate body;

[0029] 2. Add a film to the slotted license plate body shown in Figures 1c and 1d. The film has been demetallized for the corresponding slot before. Figure 1c is the front view of the license plate body, and Figure 1d is the license plate. Side view of the main body;

[0030] 3. Press the words on the front of the license plate body after adding the film as shown in Fig. 1e to obtain the front appearance of the license plate body as shown in 1f;

[0031] 4. Install an RFID chip on the back of th...

Abstract

A kind of electronic car cards comprises a body, a radio-recognition CMOS chip set in the body, multi- frequency / single frequency resonance antenna connected with the CMOS chips. The body comprises metal structure, which constitutes the whole or local part of the antenna. The body is a metal plate with an antenna pattern. The blank area of the antenna pattern is a hole, a hatch, a notch, or the combination of them. The body is the metalloid or metal plate with antenna pattern and metal-filled film. The metal-filled film is formed using a layer of material that the radio wave can penetrate bonded with a metal-filled layer with antenna pattern. The metal-filled film is pasted onto the metalloid or metal plate. The blank area of the antenna pattern of the metal board is filled with material with low dielectric constant. The blank area of the antenna pattern of the metal board is embedded with the radio-recognition CMOS chip sealed with material with low dielectric constant. Using the car cards to construct the antenna, and the performance of the antenna is fine so that it can satisfy the demand in practical application.

Description

Technical field [0001] The present invention relates to licenses, in particular to license plates, and in particular to electronic license plates. Background technique [0002] An electronic license plate is an identity recognition device based on a radio frequency identifier attached to the main body of a metal vehicle license plate. A radio frequency identifier is composed of an RFID (radio frequency identification) chip and an antenna. The relevant information of the corresponding vehicle can be used in a wide range of applications. For example, install a corresponding card reader on the road to track and record the vehicle in real time. Electronic license plates can improve the efficiency of vehicle registration and confirmation, and provide better enforcement guarantees: at the time of registration, vehicle and driver information can be stored in the RFID chip of the electronic license plate in accordance with the content prescribed by the law. When the vehicle is confirmed,...
