As can be seen from the curve S11 of the first antenna in fig. 11, it covers a low frequency band and a medium and high frequency band. Based on the curve S22 of the second antenna, the second antenna can compensate the middle and high frequency bands of the first antenna.

As shown in fig. 12, fig. 12 is a schematic diagram of isolation of an electronic device in which a conductor layer is used as two antennas, where the vertical axis represents isolation in dB, and the horizontal axis represents frequency in GHz. In the figure, a curve S12 represents an isolation curve of the first antenna and the second antenna, and as can be seen from fig. 12, the first antenna and the second antenna have better isolation.

As shown in fig. 13, fig. 13 is a graph of efficiency of a scheme in which a conductor layer is used as two antennas in an electronic device, where the vertical axis represents efficiency in dB and the horizontal axis represents frequency in GHz. Curve 313 is the system efficiency of the first antenna and curve 314 is the system efficiency of the second antenna, it can be seen that the first antenna can effectively radiate at low and medium high frequencies and the second antenna can effectively radiate at medium and high frequencies.

When the conductor layer is used as two antennas and a third antenna is added, the return loss of the first antenna and the second antenna is the same as that of fig. 11. The return loss of the third antenna is shown in fig. 14, and fig. 14 shows a return loss graph of the third antenna in the electronic device, where the vertical axis represents loss in dB, and the horizontal axis represents frequency in GHz. As can be seen from the curve S33 of the third antenna, the third antenna can have better low-band characteristics at point 1, and the third antenna can compensate the low-band of the first antenna.

As shown in fig. 15, fig. 15 is a graph of the efficiency of the first antenna to the third antenna, which the electronic device has simultaneously, with the vertical axis representing the efficiency in dB and the horizontal axis representing the frequency in GHz. Curve 315 represents the system efficiency of the first antenna, and is seen to be able to radiate effectively in the low and mid-high bands, curve 316 represents the system frequency of the second antenna, and is seen to be able to radiate effectively in the mid-high band, and curve 317 represents the system efficiency of the third antenna, and is seen to be able to radiate effectively in the low band.

As shown in fig. 16, fig. 16 is a schematic diagram of the isolation between the first antenna and the third antenna, where the vertical axis represents the isolation in dB, the horizontal axis represents the frequency, the curve S13 represents the isolation between the first antenna and the third antenna, the curve S23 represents the isolation between the second antenna and the third antenna, and the isolation between the first antenna and the second antenna is the same as that in fig. 12, and it can be seen that each antenna has a better isolation.
