Description
Technical field
It is particularly a kind of airborne the present invention relates to electricity field, more particularly to mechanics of communication, more particularly to antenna technology
Vertical fin conformal omnidirectional antenna.
Background technology
Airborne communicating antenna for aircraft requires that omnidirectional works in the horizontal plane, in the prior art airborne communicating antenna
Substantially expose to carrier, be that antenna easily realizes that omnidirectional works the advantages of this airborne mode, but need antenna to protrude and carry
Body, destroy the aerodynamic performance of carrier aircraft.Omnidirectional antenna can use the conformal airborne mode of low section after technological improvement, but
There is strict demand to the size, intensity and environmental suitability of antenna, can not realize and not change the situation of the original profile of carrier
Under, the aerodynamic performance of carrier is reached optimal.Meanwhile the antenna conformal with aircraft vertical fin is used at present, but in vertical fin
The structural metal part of increase intensity is built-in with, these structural metal parts are very big to the performance impact of omnidirectional antenna, especially direction
Figure influences greatly, to cause airborne antenna effectively omnidirectional can not work in the horizontal plane, significantly limit the conformal day of such vertical fin
The application of line.
The content of the invention
Patent of the present invention aims to overcome that the shortcomings that prior art is present, there is provided one kind is simple in construction, performance is steady
Determine, aerodynamic properties are good and meet the airborne vertical fin conformal omnidirectional antenna of plane omnidirectional job requirement.
This airborne vertical fin conformal omnidirectional antenna of patent of the present invention, including aircraft vertical fin and two omnidirectional antennas, it is described
Aircraft vertical fin include vertical fin chamber, the outer side covers of described vertical fin chamber have skin, be provided with vertical fin chamber structure gold
Belong to part, it is characterised in that：Described two omnidirectional antennas are arranged in the skin of described aircraft vertical fin and fixed respectively
In the both sides of the structural metal part of described vertical fin intracavitary, omnidirectional antenna electrically connects with a time-shared switch module, described
Time-shared switch module controls the omnidirectional antenna timesharing alternation.
Further, the omnidirectional antenna and the covering are formed in one structure.
Further, the omnidirectional antenna is symmetrical dipole.
Further, the symmetrical dipole is vertically set in the covering of the aircraft vertical fin.
The present invention operation principle be：Time-shared switch module produces Time-sharing control signal, and control is arranged on vertical fin corresponding two
Omnidirectional antenna in side skin, when omnidirectional antenna alternation when the driving of time-shared switch module is inferior of the left and right sides,
By produce radiation direction be 180 degree and be alternately present half to operative orientation figure, omnidirectional antenna is adopted using time-sharing work principle
Worked with timesharing system, efficiently solve aircraft vertical fin mucosal structure metalwork and the interference between stop and omnidirectional antenna is asked
Topic, realizes the job requirement of airborne antenna omnidirectional radiation.
Patent of the present invention compares with prior art, and its effect is positive and obvious.Patent of the present invention is by by omnidirectional
Antenna, which is arranged in aircraft vertical fin, forms conformal structure, and uses time-shared switch module to replace work when controlling one group of omnidirectional antenna etc.
Make, realize optimization and the antenna omnidirectional mode of operation of airborne antenna aerodynamic properties, the airborne vertical fin conformal omnidirectional day
Cable architecture is simple, stable performance.
Brief description of the drawings：
Fig. 1 is the front cross-sectional structural representation of patent of the present invention.
Fig. 2 is the top view cross section structural representation of patent of the present invention.
Fig. 3 is the time-shared switch module connection diagram of patent of the present invention.
Embodiment
Embodiment 1:
As shown in Figures 1 to 3, this airborne vertical fin conformal omnidirectional antenna of patent of the present invention, including aircraft vertical fin 1 and omnidirectional antenna
4, omnidirectional antenna 4 is arranged in the skin 3 of aircraft vertical fin 1, and omnidirectional antenna 4 is one group and is correspondingly arranged at the intracavitary of aircraft vertical fin 1
The both sides of structural metal part 2, omnidirectional antenna 4 are electrically connected with time-shared switch module 5, and time-shared switch module 5 is wanted according to communication is overall
Millisecond can be given birth to the Time-sharing control signal between nanosecond by asking, and for controlling the timesharing alternation of omnidirectional antenna 4, be produced horizontal
Omni-directional pattern.
Further, omnidirectional antenna 4 and covering 3 are formed in one structure, omnidirectional antenna 4 is possessed rock-steady structure.
Further, omnidirectional antenna 4 is symmetrical dipole 4.
Further, symmetrical dipole 4 is vertically set in the covering 3 of aircraft vertical fin 1.
The working method of the present embodiment is：The device produces Millisecond to point between nanosecond by time-shared switch module
When control signal, control is arranged on the omnidirectional antenna in corresponding two side skins of vertical fin, when the omnidirectional antenna of the left and right sides is in timesharing
When the driving of switch module is inferior during alternation, by produce radiation direction be 180 degree and be alternately present half to operative orientation
Figure, due to the working method that is switched fast when being used between the omnidirectional antenna of the left and right sides etc., continuous omni-directional pattern can be produced,
Aircraft vertical fin mucosal structure metalwork is efficiently solved to the interference problem between stop and omnidirectional antenna, realizes airborne antenna
The job requirement of omnidirectional radiation.
