Accordingly, the first antenna 41, the second antenna 42, and the third antenna 43 may radiate wireless signals in different directions, respectively, and interference among the first antenna 41, the second antenna 42, and the third antenna 43 may be reduced.

Wherein a frequency of the fourth wireless fidelity signal is the same as a frequency of the first wireless fidelity signal. For example, the frequency of the fourth wireless fidelity signal may also be 2.4 GHz.
Here, since the length of the fifth signal transmission part 431 is long, in order to reduce the space occupied by the third antenna 43 inside the electronic device 100, the fifth signal transmission part 431 may be provided in a curved shape, as shown in fig. 6.
