Embodiment 1

[0056] Embodiment 1: as figure 2 As shown, a stacked structure is adopted, the 13.56MHz antenna module 1130 is on the top layer, the low-frequency magnetic coupling coil 1110 is directly below it, and the 2.4GHz radio frequency antenna module 1120 is located in the middle of the shape surrounded by the low-frequency magnetic coupling coil 1110, in order to shield the low-frequency magnetic induction coil For the interference of 1110 on 13.56MHz antenna module 1130, a certain distance between 13.56M antenna module 1130 and low-frequency magnetic induction coil 1110, 1mm to 10mm is feasible, so as to realize the closed loop of 13.56MHz magnetic field lines and the outward radiation of energy.

Embodiment 2

[0057] Embodiment 2: as image 3 As shown, the difference between this embodiment and Embodiment 1 is that an anti-jamming device 1140 is provided between the 13.56 MHz antenna module 1130 and the low-frequency magnetic coupling coil 1110, and the anti-jamming device 1140 uses a wave-absorbing material in the 13.56 MHz frequency band Or it is made of magnetically permeable material that acts as a magnetic conductor for the 13.56MHz magnetic field, such as ferrite, so as to realize the closed loop of the 13.56MHz magnetic force line and the outward radiation of energy.

Embodiment 3

[0058] Embodiment 3: as Figure 4 As shown, the difference between this embodiment and Embodiment 1 and Embodiment 2 is that a tiled structure is adopted, the 13.56MHz antenna module 1130 is on the outermost layer, the low-frequency magnetic coupling coil 1110, the 13.56M antenna module 1130 and the 2.4GHz radio frequency antenna module 1120 are on the same plane, and the low-frequency magnetic coupling coil 1110 is separated from the 13.56MHz antenna module 1130 by a certain distance. Most of the magnetic field radiated by 1130 passes through the gap, and the radiation energy blocked by the low-frequency magnetic coupling coil 1110 is quite small, so that the energy of the 13.56MHz antenna module 1130 can radiate out without a blind area.

[0059] The 13.56MHz antenna module 1130 and the low-frequency magnetic coupling coil 1110 may not be on the same plane, but the 13.56MHz antenna module 1130 is located at a position not shielded by the low-frequency magnetic coupling coil ...

Abstract

The invention relates to a multiple-frequency-band antenna device for near field communication. The multiple-frequency-band antenna device comprises an interface module, a low-frequency magnetic coupling coil, a 13.56MHz antenna module and a 2.4GHz radio-frequency antenna module, wherein the low-frequency magnetic coupling coil, the 13.56MHz antenna module and the 2.4GHz radio-frequency antenna module are connected with the interface module. An interval exists between the low-frequency magnetic coupling coil and the 13.56MHz antenna module, and the low-frequency magnetic coupling coil is connected with a main control device through the interface module and sends a low-frequency alternating magnetic field to transmit data to a mobile communication terminal. The 13.56MHz antenna module emits a radio-frequency signal, is connected with the main control device through the interface module, and carries out data interaction with the mobile communication terminal. The 2.4GHz radio-frequency antenna module is connected with the main control device through the interface module and carries out data interaction with the mobile communication terminal. The multiple-frequency-band antenna device has the beneficial effects that users can operate fast and conveniently, and the multiple-frequency-band antenna device is more easily popularized.
