In some alternative embodiments of the present invention, low profile antenna 100 is closure or open planar structure or three-dimensional Structure.Thus, it is possible to the specific structure type of low profile antenna 100 flexibly be set according to actual requirement, with preferably full Sufficient practical application, enhances the diversity of low profile antenna 100, improves the applicability of low profile antenna 100.

For example, in Figure 18 example, all first antennas 1 and the equal position of all second antennas 2 in low profile antenna 100 In in same plane, now low profile antenna 100 is planar structure, and the A5 ends of low profile antenna 100 are distributing point, A5 ends It is connected with one end of feed system 3, A4 ends are not distributing points, A4 ends are not connected with feed system 3, low profile antenna 100 is to open Put;Certainly, the low profile antenna 100 of planar structure can also be (not shown) of closure.In the example of fig. 1 and 2, Not in the same plane, now low profile antenna 100 is three-dimensional structure to three first antennas 1 of low profile antenna 100;Fig. 4- In Figure 17 example, the first antenna 1 of the upside in low profile antenna 100 and remaining first antenna 1, the second antenna 2 do not exist In same plane, now low profile antenna 100 is also three-dimensional structure.Wherein, shown in Fig. 1, Fig. 2, Fig. 6, Figure 11, Figure 14 and Figure 17 Low profile antenna 100 A4 ends and A5 ends be distributing point, and the one end of A4 ends and A5 ends with feed system 3 is connected, this When low profile antenna 100 be closure, Fig. 4 and the low profile antenna 100 shown in Fig. 5 are open.

As shown in Fig. 1-Figure 17, low profile antenna 100 can also include connecting line 4, the antenna 2 of first antenna 1 and second it Between by connecting line 4 be connected.It is understood that when low profile antenna 100 includes multiple connecting lines 4, multiple connecting lines 4 Length and structure type can be set to identical or incomplete same according to actual conditions.For example, in the example of fig. 1 and 2, Low profile antenna 100 includes six connecting lines 4, and the length of six connecting lines 4 is incomplete same, and six connecting lines 4 are straight Line style delay line;In Fig. 4-Figure 17 example, the connecting line 4 of low profile antenna 100 is plane delay line.It is appreciated that , connecting line 4 can also be shaped form delay line, curved face type delay line etc..

Certainly, low profile antenna 100 can also be not provided with connecting line 4, and directly first antenna 1 is connected with the second antenna 2 (as shown in figure 18).

In some embodiments of the invention, first antenna 1 is three, and the second antenna 2 is two, two the second antennas 2 In one of them be connected between one of them in three first antennas 1 and one of them in two other, two Another in two antennas 2 is connected to one of them in three first antennas 1 between another in two other.By This, low profile antenna 100 is simple in construction, easily realizes.For example, as shown in Fig. 1-Figure 18, three first antennas 1 are respectively A1A2 Section, A3A4 section and A5A6 section, respectively B1B2 sections of two the second antennas 2 and B3B4 sections, wherein B1B2 sections of two ends respectively with A1A2 sections are connected with A3A4 sections, and B3B4 sections of two ends are connected with A1A2 sections and A5A6 sections respectively.Thus, low profile antenna 100 Coupling can by force can be weak, realize the good omni-directional of low profile antenna 100 and higher gain, meanwhile, with low section characteristic (for example, the height h of low profile antenna 100 can meet h < 6mm), occupies little space, so as to realize the small of electronic equipment Type.It is understood that the combination connecting mode not limited to this of the antenna 2 of first antenna 1 and second.By first antenna 1 and Two antennas 2 combine after connection, then can form low profile antenna 100 by suitable feeding classification.

In the further example of the present invention, two other in three first antennas 1 is located in three first antennas 1 The same side of one of them.For example, as shown in Fig. 1-Figure 18, one of first antenna 1 in three first antennas 1 is located at low Two other in the top of profile antenna 100, three first antennas 1 is each provided at the lower section of above-mentioned first antenna 1, and this two First antenna 1 can left and right interval setting.Thus, it further ensure that low profile antenna 100 has low section characteristic, its profile It is smaller.

In some optional examples of the present invention, at least one of which is planar structure in three first antennas 1, three the In one antenna 1 is generally aligned in the same plane;Or, in two other in three first antennas 1 is generally aligned in the same plane, and three first One of them in antenna 1 is vertical with the plane where two other in three first antennas 1;Or three first antennas 1 In two other in one of them be that another in planar structure, two other in three first antennas 1 is three-dimensional In structure, and three first antennas 1 one of them with where one of in two other in three first antennas 1 Plane is vertical.Thus, the applicability of low profile antenna 100 is further increased.
