Detailed description of the invention
It should be noted that in the case of not conflicting, the embodiment in the application and the feature in embodiment can phases
Combination mutually.
As it is shown in figure 1, the implementation method of a kind of multiple antennas UAS, being applied to UAS, system includes distant
Control terminal, unmanned plane terminal and mobile communications network, described unmanned plane terminal includes that processor, 3G/4G communication module, WIFI are logical
Letter module, bluetooth communication；Described remote terminal is connected with unmanned plane terminal by WIFI communication module or bluetooth communication
Connect；Described remote terminal is connected with the 3G/4G communication module in unmanned plane terminal by mobile communications network；Described 3G/4G leads to
Letter module includes the 3G/4G antenna being arranged on unmanned plane top, and described WIFI communication module includes being arranged on gold on the left of unmanned plane
Belonging to the WIFI antenna of wing, described bluetooth communication includes being arranged on the Bluetooth antenna of metal wings on the right side of unmanned plane.Process
Device can select 3G/4G communication mode, WIFI communication mode or Blue-tooth communication method as required.
Described method includes step:

As in figure 2 it is shown, as it is shown in figure 1, antenna is overall in reversed F-typed structure, described antenna is arranged on just going up of unmanned plane top
Side, described antenna includes being parallel to first parallel arms 11 on unmanned plane top, being perpendicular to first upright arm 12 on unmanned plane top, described
First parallel arms 11 joins with the first upright arm 12, and interface point extends along the first parallel arms direction and forms the second parallel arms 13, institute
State the second parallel arms 13 extend and be bent to form the second upright arm 14 to direction, vertical unmanned plane top so that antenna is overall in inverted f
Type structure.
As it is shown on figure 3, described WIFI antenna be on the left of unmanned plane metal wings crack arrange the first collapsible gap
Antenna.Described first collapsible slot antenna is the collapsible slot antenna of square wave type accordion shaped form.Described first collapsible
The collapsible gap overall length of slot antenna is equal to 1/2nd of WIFI communications band center frequency wavelength.
In like manner, Bluetooth antenna uses and is similar to the structure of WIFI antenna, cracks setting for metal wings on the right side of unmanned plane
The second collapsible slot antenna.Described second collapsible slot antenna is the sky, collapsible gap of square wave type accordion shaped form
Line.The collapsible gap overall length of described second collapsible slot antenna equal to Bluetooth communication frequency range center frequency wavelength two/
One.
According to aerial radiation principle, the infinitely great and the thinnest gap in ideal conducting plane is referred to as preferable gap.Reason
Thinking that the electric field on gap is vertical with the long limit in gap, its amplitude drops to zero at the two ends in gap.This Electric Field Distribution with have
Distribution of Magnetic Field on the conductor oscillator of same size is just the same, say, that same frequency, the gap being of the same size
Antenna has complementary characteristic with the antenna that conventional antithesis antenna is a pair complementation, their CURRENT DISTRIBUTION and Distribution of Magnetic Field.Root
Understanding according to the duality of electromagnetic field, the electromagnetic field that the electromagnetic field that preferable gap is radiated produces with complementary oscillator has identical knot
Structure, simply the electric field intensity of oscillator is corresponding to the magnetic vector in gap, and the magnetic vector of oscillator is corresponding to the electric field intensity in gap
?.Monopole antenna the most conventional is also generally to walk into folding wiring (also referred to as Meander line) to compress
The space that antenna takies, unipole antenna could also say that a variant of antithesis antenna simultaneously, according to the antithesis above said
Complementary characteristic, equally uses folding fluting to shorten the size of slot antenna on slot antenna.Here it is WIFI
Source with Bluetooth antenna mentality of designing.
When metal wings directly as the radiator plane of wireless communication terminal when, can with convenient antenna and wing altogether
Shape, and radiator plane area can be increased, thus improve antenna performance.Metal wings is equivalent to a preferable ground level, folding
The width of the clearance channel in stacked gap 20 is much smaller than length and the width of metal chassis, the collapsible gap 20 in collapsible gap 20
Width is preferably 1.5mm.Obvious, collapsible gap 20 width does not limit to this value, can adjust as required.Collapsible gap
Electric field on 20 is vertical with the length extension direction in collapsible gap 20, and its amplitude drops at the two ends in collapsible gap 20
Zero.The polarised direction of collapsible gap 20 antenna becomes 90 angles with the entire length direction in collapsible gap 20.
The present invention is by arranging 3G/4G communication module, WIFI communication module, bluetooth communication and right on unmanned plane
The selection priority of communication mode is arranged, and overcomes the problem that in prior art, UAV Communication mode is single, it is achieved that unmanned
Machine is connected with the communication of remote terminal, can freely switch communication mode, effective guarantee in different distance, varying environment
The communication stability of unmanned plane terminal and remote terminal and reliability.Selection priority setting to communication mode also brings
Unmanned plane saves the beneficial effect of electric energy.
The composite can be widely applied to various UAS.
