In the present embodiment, first radiation branch 12 and the second radiation branch 13 can using slender threads system at,
It can also be designed to the structure types such as plate antenna.When first radiation branch 12 and the second radiation branch 13 are designed to plate
When shape antenna, the plate antenna can be made of rectangular metal, and this antenna structure is in the case where headroom is relatively poor
Also there can be preferable radiation efficiency.
Below with reference to figure 5-8, the working principle of the antenna assembly of the present embodiment is specifically described.
As shown in fig. 7, when the intelligent communications terminal 70 of the antenna assembly configured with the present embodiment is located at special electromagnetism ring
Under border, such as when underground piping, garage etc. be narrow and closed transmission environment, due to the electromagnetic transmission ring in this relative closure
In border 71, with such as base station receiving device 72(corresponding to intelligent communications terminal 70) often it is provided only with one, and usual position
In specific direction, such as in the extension path of pipeline or around the import or export of pipeline, therefore, to antenna assembly
Transmitting-receiving performance in particular directions has specific aim and higher requirement.In order to ensure intelligent communications terminal 70 can be with its institute
The forms of radiation of antenna assembly should be adjusted to be directed toward the orientation spoke of receiving device 72 by corresponding 72 reliable communication of receiving device
It penetrates, by the radiation gain of enhancing antenna assembly in the specified direction, to improve intelligent communications terminal 70 in the specific direction
On communication performance.
Specifically, it when intelligent communications terminal 70 is located at the electromagnetic environment of relative closure as shown in Figure 7, can control
First radiation branch 12 and the second radiation branch 13 separate, shape angle in 90 °.At this point, the antenna of intelligent communications terminal 70
Form is V-type directional aerial, as shown in Figure 1, sending and receiving wireless signal by V-type directional aerial.It is fixed that Fig. 5 shows V-type
It is orientation by the magnetic field radiation direction that V-type directional aerial is formed, by main lobe 51 and minor lobe to the radiation direction of antenna
52,53 composition.Wherein, main lobe 51 is the Net long wave radiation lobe of V-type directional aerial, is directed toward the spoke of as V-type directional aerial
Direction is penetrated, the gain of V-type directional aerial in this direction can be much higher than omnidirectional antenna.The direction for adjusting V-type directional aerial, makes it
The main lobe 51 of formation is directed toward the direction where receiving device 72, is increased by increasing the radiation of V-type directional aerial in this direction
Benefit, to ensure intelligent communications terminal 70 and 72 linking communications of receiving device.
