In some embodiments of the invention, first antenna parts 1 and the second antenna element 2 are tabular. Alternatively, as shown in figs 1 to 6, in first antenna parts 1 and the second antenna element 2 are generally aligned in the same plane, it is preferable that first antenna parts 1 and the second antenna element 2 can be integrally formed by metallic plate or sheet metal. Still optionally further, as shown in Figure 7 and Figure 8, first antenna parts 1 are positioned at different plane and spaced a predetermined distance from the second antenna element 2.

It is understandable that, although one of them 2a and another 2b of two shown in Fig. 9 a the second antenna element 2 connected first antenna parts 1 respectively are at grade, but in other embodiments of the invention, they can not be in the same plane, it is to say, antenna element 100 as shown in Figure 7 and Figure 8 can be bent.
In some embodiments of the invention, the second antenna element 2 is triangle or rectangle. In the example of Fig. 2, the second antenna element 2 is all formed as the shape of similar triangle, and specifically, the long limit of the second antenna element 2 is parallel with first antenna parts 1 and adjacent, and additionally both sides are formed as arcuate line segment, and it is most advanced and sophisticated to intersect at one.It addition, in the example of Fig. 3-Fig. 6, the second antenna element 2 is all formed as rectangular shape, now, the long limit of the rectangle being formed as the second antenna element 2 is parallel and adjacent with the first of first antenna parts 1 (or second) side, as shown in Figure 3.

In some optional examples, as shown in Figure 13 and Figure 14, the comb 20 of the second antenna element 2 of pectination is in transversely equal sized of first antenna parts 1 and the horizontal equal spacings along first antenna parts 1. Alternatively, the width transversely of each comb of the second antenna element 2 can be equal respectively, and laterally equidistantly also equal between comb. Such as shown in Figure 13. But, as shown in figure 14, the width transversely of each comb of the second antenna element 2 can be unequal each other, such as can be gradually increased along the width of the horizontal direction of first antenna parts 1, the comb of the second antenna element 2 or be gradually reduced, still optionally further, laterally equidistantly also can be gradually increased (not shown go out) between the comb of the second antenna element 2 or be gradually reduced (as shown in figure 14), or each other not etc. and there is no rule. It will be appreciated that the size transversely of the comb of the second antenna element 2 equidistantly can be different with specific design with laterally, no longer limit in detail at this.
In another optional example, as shown in figure 15, the comb 20 of the second antenna element 2 of pectination size in the longitudinal direction of first antenna parts 1 being laterally gradually increased from both sides towards centre along first antenna parts 1.
Thus, by regulating lateral dimension and the longitudinal size of the comb 20 of the second antenna element 2 of pectination, it may be achieved the wave beam at different frequency controls.
It is understandable that, although the example provided in Fig. 2-Fig. 6, Figure 13-Figure 15 has illustrated two the second antenna elements 2, and shape determines, but the quantity that those skilled in the art are appreciated that the second antenna element 2 is changed with similar principle with shape.

Alternatively, connecting antenna part 21 and be joined directly together with first antenna parts 1, coupled antenna portion 22 is spaced apart with connecting antenna part 22, for instance by including but not limited to that the coupled modes of Capacitance Coupled or inductive couple.
Specifically, for instance, Figure 10 and Figure 17 illustrates the antenna element 100 including second antenna element 2, and the second antenna element 2 includes connecting antenna part 21 and coupled antenna portion 22. Figure 12 illustrates the antenna element 100 including two the second antenna elements 2. Figure 16, Figure 18-Figure 20 illustrates the antenna element 100 including two the second antenna elements 2, two second antenna elements 2a, 2b include two parts respectively, specifically, one of them second antenna element 2a includes connecting antenna part 21a and coupled antenna portion 22a, another second antenna element 2b and includes connecting antenna part 21b and coupled antenna portion 22b.
