Detailed description of the invention
Refer to Figure 1A to Fig. 1 C, Figure 1A to Fig. 1 C be respectively a dual-band antenna 10 of the embodiment of the present invention etc. visual angle 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, the 102nd, dual-band antenna 10 comprises one first radiant body the 100th, one second radiant body
One earthing member the 106th a, matching parts the 108th, a short circuit part 110 and a connection piece 112.First radiant body 100 works in one first frequency
Rate and be parallel to an X/Y plane (correspond to the first plane), the first radiant body 100 has a symmetrical structure, and it can be substantially in a pair of
Rhombus, wherein the first radiant body 100 has hypotenuse sd_1, sd_2 and a central part ct, and hypotenuse sd_1, sd_2 are interconnected in
The central part ct of one radiant body 100.Second radiant body 102 can in a T-shaped, the second radiant body 102 work in a second frequency and
Being parallel to a YZ plane (corresponding to the second plane), dual-band antenna 10 can be presented by a load point 104 of the second radiant body 102 bottom
Entering signal, the second radiant body 102 is arranged between hypotenuse sd_1, sd_2, and adjacent to hypotenuse 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 there is spacing GP, short circuit part 110 and connector 112 are all parallel to YZ plane.Short circuit part 110 is used for connecting the first radiant body
The one second side s2 of the central part ct of 100 and earthing member 106, connector 112 is used for connecting the central part ct of the first radiant body 100
The first side s1 and matching parts 108.
It is noted that dual-band antenna 10 is predominantly in the antenna being parallel to YZ plane generation polarised direction, because of the first spoke
Beam 100 has symmetrical structure, and is being parallel to the electromagnetic component of X/Y plane in the electromagnetic energy that the first radiant body 100 is launched
Can repeal by implication, and be unlikely to have influence on the second radiant body 10 in the electromagnetic energy being parallel to the generation polarization of YZ plane.Yu Yishi
Executing in example, dual-band antenna 10 can be vertical polarized antenna, although the first radiant body 100 produces electromagnetic energy in horizontal polarization directions
