In the case of the antenna structure including the first antenna and the second antenna, please refer to fig. 6a to 6e for the current mode of the first antenna in each working frequency band. Fig. 6a is a schematic view of a main current mode when an operating frequency band of the first antenna is an n41 frequency band 2.6GHz, and a main radiation structure corresponding to the n41 frequency band is a second sub-branch; fig. 6b is a schematic diagram of a main current mode when an operating frequency band of the first antenna is 3.5GHz in an n77 or n78 frequency band, where main radiation structures corresponding to the n77 or n78 frequency band are a first sub-branch and a second sub-branch; fig. 6c is a schematic view of a main current mode when the operating frequency band of the first antenna is n79 frequency band 4.5GHz, and the main radiation structure corresponding to the n79 frequency band is a first radiation branch, a first sub-branch, and a second sub-branch; fig. 6d and fig. 6e are schematic diagrams of the current main mode when the working frequency band of the first antenna is the wifi5G frequency band at 5.15GHz and 5.85GHz, respectively, and the main radiation structures corresponding to the wifi5G frequency band are the first radiation branch, the first sub-branch, the second sub-branch, and the third sub-branch.
In the case of the antenna structure including the first antenna and the second antenna, please refer to fig. 7a to 7d for the current mode of the second antenna in each working frequency band.

The reason why the isolation between the first antenna and the second antenna is good is that the first radiation branch 101 is shorter and has a single routing form compared with the second radiation branch 102, and the energy radiated by the second antenna is more prone to be coupled to the second radiation branch 102 (3.3 GHz-6GHz resonant structure) to be re-radiated, and the first radiation branch 101 presents a high-impedance mismatch characteristic in these frequency bands relatively, so that the isolation between the first antenna and the second antenna is also guaranteed.
