Specific embodiment
Figure 1A to Fig. 1 C is please referred to, Figure 1A to Fig. 1 C is respectively that the equal visual angles of a dual-band antenna 10 of the embodiment of the present invention show
Intention, schematic top plan view and schematic side view, for convenience of explanation, Figure 1A to Fig. 1 C is labeled with the coordinate system of X, Y, Z axis, with
Display view angle position.As shown in Figure 1A to Fig. 1 C, dual-band antenna 10 include one first radiator 100, one second radiator 102,
The short-circuit part 110 of one earthing member 106, a matching parts 108, one and a connection piece 112.First radiator 100 works in one first frequency
It rate and is parallel to an X/Y plane (correspond to the first plane), it can substantially be in a pair of that the first radiator 100, which has a symmetrical structure,
Diamond shape, wherein the first radiator 100 has bevel edge sd_1, sd_2 and a central part ct, bevel edge sd_1, sd_2 are interconnected in the
The central part ct of one radiator 100.Second radiator 102 can be in a T shape, the second radiator 102 work in a second frequency and
It is parallel to a YZ plane (corresponding to the second plane), dual-band antenna 10 can be presented by a load point 104 of 102 bottom end of the second radiator
Enter signal, the second radiator 102 is set between bevel edge sd_1, sd_2, and adjacent to bevel edge sd_1, sd_2 and central part ct
One first side s1.In addition, earthing member 106 and matching parts 108 are all parallel to X/Y plane, and earthing member 106 and matching parts 108 it
Between have a spacing GP, short-circuit part 110 and connector 112 are all parallel to YZ plane.Short-circuit part 110 is used to connect the first radiator
Second side s2 and earthing member 106 of 100 central part ct, connector 112 are used to connect the central part ct of the first radiator 100
The first side s1 and matching parts 108.
It is noted that dual-band antenna 10 is mainly in the antenna for being parallel to YZ plane generation polarization direction, because of the first spoke
Beam 100 has symmetrical structure, and in the electromagnetic component for being parallel to X/Y plane in the electromagnetic energy that the first radiator 100 is emitted
It can repeal by implication, and be unlikely to influence the second radiator 10 and generate polarized electromagnetic energy in being parallel to YZ plane.Yu Yishi
It applies in example, dual-band antenna 10 can be vertical polarized antenna, although the first radiator 100 is in generating electromagnetic energy in horizontal polarization directions
Amount, but because the first radiator 100 has symmetrical structure, the levels electromagnetic component that the first radiator 100 is emitted is mutual
Payment, the i.e. vertical electromagnetic component of dual-band antenna 10 are greater than levels electromagnetic component.
On the other hand, dual-band antenna 10 can be applied to an antenna system, for example, referring to FIG. 2, Fig. 2 is the present invention
The schematic diagram of one antenna system 20 of embodiment.Antenna system 20 may be disposed in a wireless device, and antenna system 20 includes one
