The antenna structure with improved isolation provided by the embodiment of the present invention will now be described.
Referring to fig. 1, in one embodiment of an antenna structure for improving isolation, the antenna structure for improving isolation includes a first antenna structure 1 and a second antenna structure 2 that are arranged at an interval, a metal spacer 3 for enhancing isolation between the two antennas is arranged between the first antenna structure 1 and the second antenna structure 2, an arrangement direction of the first antenna structure 1, the metal spacer 3, and the second antenna structure 2 is a first direction, and the first direction and the second direction are perpendicular to each other. The communication frequency band of the first antenna structure 1 is a first frequency band and a second frequency band, the communication frequency band of the second antenna structure 2 is a first frequency band and a third frequency band, the two antenna structures are provided with the first frequency bands, because the frequency bands are close, when one antenna structure works, the current in the antenna structure can be coupled to the metal floor, and the current flows to the other antenna structure through the metal floor, so that the electromagnetic interference is caused to the other antenna structure. The metal isolating strip 3 is arranged between the first antenna structure 1 and the second antenna structure 2, and the metal isolating strip 3 is grounded, so that after the current of one antenna structure is coupled to the metal floor, the current can be coupled to the metal isolating strip 3, the current coupled to the other antenna structure is reduced, and the interference between the first antenna structure 1 and the second antenna structure 2 is reduced.
The antenna structure for improving isolation of the embodiment includes the first antenna structure 1 and the second antenna structure 2 which are arranged at an interval, the communication frequency band of the first antenna structure 1 is the first frequency band and the second frequency band, the communication frequency band of the second antenna structure 2 is the first frequency band and the third frequency band, when the distance between the first antenna structure 1 and the second antenna structure 2 is too close, the first frequency bands of the two antenna structures have the same working frequency, and mutual interference is easily caused. By providing the metal spacer 3 between the first antenna structure 1 and the second antenna structure 2, when one of the antenna structures is in operation, the current coupling of the antenna structure can be coupled to the metal spacer 3, so that the current coupled to the other antenna structure is reduced, which is equivalent to reducing the influence on the other antenna structure, thereby increasing the isolation between the first antenna structure 1 and the second antenna structure 2.
Optionally, the first frequency band is an N41 frequency band, specifically, 2.5GHz to 2.69 GHz; the second frequency band is an N78 frequency band, specifically 3.3GHz to 3.8 GHz; the third frequency band is an N79 frequency band, specifically 4.4GHz to 5 GHz.

When the distances between the first antenna structure 1 and the second antenna structure 2 and the metal floor are too close, the clearance of the antenna structures can be affected, the distances between the first antenna structure 1 and the metal floor and the second antenna structure 2 cannot be too far, otherwise, the thickness of the mobile terminal is too large, and the miniaturization of the mobile terminal is not facilitated.

When the distance between two antenna structures is too small, the isolation improvement effect of the metal isolating strip 3 is poor, and when the distance between two antenna structures is too large, the interference between the two antenna structures is very small, and the metal strip does not need to be used. Wherein, the distance between the first antenna structure 1 and the second antenna structure 2 is the distance between the two closest sides of the first antenna structure 1 and the second antenna structure 2. The distance between the metal isolation strip 3 and the first antenna structure 1 is 3mm to 7mm, namely the metal isolation strip 3 is arranged in the middle of the first antenna structure 1 and the second antenna structure 2 or close to the center.

Referring to fig. 2 and 3, in one embodiment of the antenna structure with improved isolation, two ends of the metal isolation strip 3 are grounded, and only two ends of the metal isolation strip 3 are connected to the metal floor, that is, the metal isolation strip 3 is partially connected to the metal floor. Referring to fig. 3, in another embodiment of the antenna structure with improved isolation, a side of the metal isolation strip 3 facing the metal floor extends toward the metal floor, and the side of the metal isolation strip 3 is fully connected to the metal floor, so that the metal isolation strip 3 is fully connected to the metal floor, and compared with a partial connection mode, the bonding area of the metal isolation strip 3 and the metal floor in this embodiment is larger, and the isolation effect is better.
As shown in fig. 6, fig. 6 is a graph comparing the reflection coefficients of the embodiment of fig. 2 and the embodiment of fig. 3 without the metal spacer. The graph in fig. 6 corresponds to the antenna structure, and the remaining structures are completely the same except for the structural difference of the metal isolation strip 3. In the embodiment of fig. 2, the distance between the first antenna structure 1 and the second antenna structure 2 and the metal floor is 3.2mm, the width of the metal spacer 3 is 1mm, the length of the metal spacer is 5.2mm, the length of the first antenna structure 1 in the first direction is 12.4mm, the length of the first antenna structure 1 in the second direction is 5.3mm, the length of the second antenna structure 2 in the first direction is 12.4mm, and the length of the second antenna structure 2 in the second direction is 8 mm. In fig. 6, curve 1 is a reflection coefficient curve without the metal spacer 3, the isolation without the metal spacer 3 is 6.3dB, curve 2 is a reflection coefficient curve of the embodiment of fig. 2, and compared with the case without the metal spacer 3, the isolation is improved by 3.3dB, and curve 3 is a reflection coefficient curve of the embodiment of fig. 3, and compared with the case without the metal spacer 3, the isolation is improved by 5 dB.
