Fig. 3 is the generalized section of the directional diagram of main antenna and slave antenna among Fig. 1 embodiment.
[embodiment]
As shown in Figure 1, be the antenna structure of the mobile communication terminal of an embodiment.This antenna structure comprises printed circuit board (PCB) 10 and is located at the double antenna 20 on the printed circuit board (PCB) 10.Wherein double antenna 20 comprises main antenna 22 and slave antenna 24, and main antenna 22 is located at an end of printed circuit board (PCB) 10, and slave antenna 24 is located at the middle part of printed circuit board (PCB) 10.
In the present embodiment, main antenna 22 is planar printed antenna with slave antenna 24, and is preferably the helical antenna that external overall is shaped as rectangle.Certainly, in other embodiments, also can select the antenna of other shapes for use.
In the present embodiment, be shaped as the helical antenna of rectangle for external overall, be located at the antenna of printed circuit board (PCB) 10 1 ends, promptly the length direction of main antenna 22 extends along the Width of printed circuit board (PCB) 10.Be located at the antenna at printed circuit board (PCB) 10 middle parts, promptly the length direction of slave antenna 24 extends along the length direction of printed circuit board (PCB) 10.
The slave antenna 24 at printed circuit board (PCB) 10 middle parts specifically is the position that is positioned between 1/3rd length to three on the printed circuit board (PCB) 10/two length, promptly among the figure between two dotted lines.
Preferably, the axis of the Width of slave antenna 24 overlaps with the axis of printed circuit board (PCB) 10 Widths, and promptly slave antenna 24 is positioned at the center of printed circuit board (PCB) 10.
Among Fig. 1, the feedback of main antenna 22 point is positioned at the end of main antenna 22 away from slave antenna 24, and the feedback point of slave antenna 24 is positioned at the middle part of slave antenna 24.Based on the change of the feedback point position of slave antenna 24 with respect to the traditional double antenna arrangement; The CURRENT DISTRIBUTION of slave antenna 24 on printed circuit board (PCB) 10 changes (current direction of main antenna 22 and slave antenna 24 is shown in arrow among Fig. 1), thereby the directional diagram (with reference to figure 2) of 24 types of apple shapes of slave antenna is reversed.Specifically be, the directional diagram of main antenna 22 is similar with tradition, and the directional diagram of slave antenna 24 then is on the basis of main antenna 24 directional diagrams, and Z axle and X axle are exchanged, and has realized reversing of directional diagram.
With reference to figure 3, main antenna 22 directional diagrams are parallel to the profile quadrature on x-y plane along profile that is parallel to the x-y plane and slave antenna 24 directional diagrams edge, thereby the correlation between main antenna 22 and the slave antenna 24 is lower.
When slave antenna 24 moves between 1/3rd length to three/two length of printed circuit board (PCB) 10; Correlation between main antenna 22 and the slave antenna 24 changes thereupon; When the feedback point was positioned at printed circuit board (PCB) 10 centers, the correlation between main antenna 22 and the slave antenna 24 was minimum.
In other embodiments; Difform antenna; For example the antenna of non-plane print antenna, non-helical antenna and other shape such as horn antenna, logarithm periodic antenna, Yagi antenna etc. also can be arranged main antenna and slave antenna with reference to the foregoing description, make the directional diagram lap between main antenna and the slave antenna minimum; Reduce correlation, thereby improve the throughput of data.
The above embodiment has only expressed several kinds of execution modes of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection range of the utility model.Therefore, the protection range of the utility model patent should be as the criterion with accompanying claims.
