In the prior art, the Envelope Correlation Coefficient (ECC) indicates the cross-correlation of the received complex patterns of the two antennas in three-dimensional space, specifically indicating the degree of similarity between the amplitude and phase patterns of the two antennas. It is generally expected that the radiation performance of the two antennas can complement each other, and the radiation patterns of the two antennas are largely different. In the multi-antenna layout of Figure 1, the envelope correlation coefficient between the antennas in some locations is poor, which reduces the transmission efficiency of the mobile phone.

At present, the mobile phone is to isolate the far field communication antenna from the near field communication antenna, so that the far field communication antenna sets the far field communication radiator, and the near field communication antenna sets the near field communication radiator.

However, it is often prone to defects in which the far-field electromagnetic signal and the near-field electromagnetic signal interfere with each other. In order to avoid mutual interference between the far-field electromagnetic signal and the near-field electromagnetic signal, the gain of the far-field electromagnetic signal and the gain of the near-field electromagnetic signal can only be reduced, resulting in weaker far-field electromagnetic signals and near-field electromagnetic signals, thereby reducing the user experience.

The slit 6131 divides the main board 630 into two interconnected radiating arms 6135, and the slit 6131 itself forms a capacitance, so that the main board 613 can radiate electromagnetic waves of different resonance frequencies, thereby increasing the antenna device 60. bandwidth.

Further, the slit 6131 faces the micro slit strip 621, the second open end 6133 faces the first open end 6211, and the second closed end 6134 faces the closed end 6212. Since the feeding point 6132 is located at the edge of the slit 6131, the main board 630 radiates electromagnetic wave intensity at the slit 6131 at the maximum, and the slit is made by facing the micro slit tape 621 to the slit 6131.

In turn, the terminal back cover 622 receives a feed signal, and the terminal back cover 622 can also radiate an electromagnetic signal. Since the terminal back cover 622 is electrically connected to the main board 630 via the first ground conductor 614, electromagnetic signals of different resonance frequencies can be radiated, so that the frequency band of the antenna device 60 is increased, that is, the antenna device is increased. 60 bandwidth. Specifically, the number of the first ground conductors 614 is plural, and the plurality of the first ground conductors 614 are arranged equidistant along the edge of the micro slit tape 621. A plurality of the first ground conductors 614 are equally arranged along the edge of the slit 6131. The edge of the slit 6131 is grounded, thereby reducing the potential of the slit 6131, so that the resonance frequency at the slit 6131 is lowered. Low, thereby making the resonance frequency of the entire main board 630 smooth, so that the antenna device 60 is signal stable.

Further, the metal housing 620 further includes a terminal front cover 623 that is covered with the terminal back cover 622, and the radiation component 610 is located between the terminal rear cover 622 and the terminal front cover 623.
