NFC english acronym Near Field Communication is a near field wireless communication antenna that can provide a wireless connection for secure and rapid communication. NFC has the characteristics of short distance, high bandwidth, low energy consumption and the like, is compatible with the existing non-contact smart card technology, and therefore gradually becomes a formal standard of more and more manufacturers.
The application of antennas, in particular planar loop or spiral antennas, is very widespread in the field of near field communication and in the field of wireless charging.
Most of the existing antennas are single-panel antennas, which results in low space utilization, insufficient area or structural space, and difficulty in meeting performance requirements.
For example: the patent application No. 201680004943.9 provides an NFC antenna module that connects a side cover (i.e., a metal frame) formed at one side of a portable terminal to an antenna pattern such that the side cover functions as an auxiliary radiator of the antenna pattern. The NFC antenna module provided includes: a side cover made of a metal material and coupled to one side of the portable terminal; an antenna pattern having one end connected to a short-range communication chipset embedded in the portable terminal; a first terminal portion of the antenna pattern, one end of the first terminal portion being connected to the short-range communication chipset and the other end being connected to the side cover; and a second terminal part having one end connected to the other end of the antenna pattern and the other end connected to the side cover.
The above patent can realize the NFC function through the antenna pattern, but the design of the single panel antenna greatly reduces the space utilization.
Therefore, it is necessary to design a dual panel antenna that has a sufficient utilization of structural space and good performance.

It should be noted that variations and modifications could be made by those skilled in the art without departing from the inventive concept. These are all within the scope of the present invention.
As shown in fig. 1 to 3, the dual-panel antenna based on bridge jumper according to the present invention includes a substrate 1, and a first metal coil 2 and a second metal coil 3 disposed on two sides of the substrate 1. The base material 1 can be a PCB or an FPCB flexible carrier plate, the first metal coil 2 and the second metal coil 3 are metal conductors and are formed by horizontally winding the same line width and line distance on two sides of the base material 1, and the first metal coil 2 and the second metal coil 3 have the same number of coil turns.
