It is bent on the line segment formed between the inflection point 4022 of fixed rack 402.In this embodiment, the material of fixed bracket 402
Rigid material can be selected.
In some embodiments, pass through gear between the small rack 4021 on the same fixed bracket 402
The change (bending) of angle between the two is realized in cooperation.In this embodiment, small rack 4021 can be realized by gear shaft
Connection, such as a small rack in two small racks 4021 is fixed on gear shaft, it is not sent out with the rotation of gear shaft
Raw any change in location, another small rack then passes through rotation axis and gear assembly cooperation is fixed on gear shaft, gear assembly
Gear cooperates between gear shaft, and when gear rotates between gear assembly and gear shaft, this small rack then can be with rotation axis
For center of circle rotation, the variation of the angle between two small racks is realized, and then realize bending bending.
In some embodiments, the stereotyped structure 400, comprising: the ultra-wide band antenna is arranged in one or more
The holding part 403 of bending place.Preferably, holding part 403 is in " V "-shape structure, by the way that holding part 303 is placed on ultra-wide band day
The bending place of line, realization is to the bending of ultra-wide band antenna, the holding of bending degree.It include clamping in the utility model embodiment
The structure of the stereotyped structure 400 of part 403 is simple, is easily installed, dismantles.
In some embodiments, the stereotyped structure 400, comprising: one or more is arranged far from the ultra-wide band day
The connector of the bending place of line, to by the ultra-wide band antenna since two faces being bent to form are maintained at a certain distance.
The connector can be wire rod rigid or flexible.
Above-mentioned stereotyped structure can be used in any combination in the utility model embodiment.
It should also be appreciated by one skilled in the art that various illustrative logical boxs, mould in conjunction with the embodiments herein description
Electronic hardware, computer software or combinations thereof may be implemented into block, circuit and algorithm steps.In order to clearly demonstrate hardware and
Interchangeability between software surrounds its function to various illustrative components, frame, module, circuit and step above and carries out
It is generally described.Hardware is implemented as this function and is also implemented as software, depends on specific application and to entire
The design constraint that system is applied.Those skilled in the art can be directed to each specific application, be realized in a manner of flexible
Described function, still, this realization decision should not be construed as a departure from the scope of protection of this disclosure.
