For example, taking the application of three different types of antennas, namely GPS, 4G, and contactless antennas, to a POS machine device as an example. In the related art, it is necessary to wind the GPS, 4G, and contactless antennas around the housing of the POS machine respectively. Not only is the winding process complex, but also a relatively large amount of winding space is required, which is not conducive to use.
