Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without creative efforts
Embodiment belongs to the scope of protection of the invention.
As shown in Figure 1 and Figure 2, the present invention provides a kind of police vehicle positioning antenna assembly, which is arranged on police vehicle
Body luggage carrier（It is not shown in figure）On, which is fixedly connected with roof, and the making of luggage carrier can be selected according to different automobile types
Corresponding metal luggage carrier is with reference to template, is molded using on-macromolecular nonmetallic materials or mold machine-shaping is corresponding
The luggage carrier of style.Luggage carrier can be fixedly connected with roof by modes such as bolt or rivets, it is ensured that securely.Police vehicle positioning
Antenna assembly includes luggage frame 1, luggage net 2, log-periodic antenna 3, fixing 4, star-like nut 5, connection cross bar 6；Luggage
Frame 1 carries out welding or fixed-type using nonmetallic high molecular tubing or plate, and luggage frame 1 is additionally provided with support rail 7, uses
In support luggage net 2, support rail 7 can be made into solid and hollow two kinds of structures, and be added using nonmetallic high molecular material
Work, and the contour structures form of needs according to the installation site difference of its luggage frame 1, can be processed into respectively.Support rail 7 is with connecting
It connects cross bar 6 to be bolted to connection, connecting screw 6 is fixed to police by the activity cooperation with fixing 4, star-like nut 5
With on car body luggage carrier, fixing 4 is made of a pair of of fixinig plate, and one end of fixinig plate is equipped with to be consolidated for what connecting screw 6 passed through
Determine hole 8, the shape of mounting hole is identical with the shape of connecting screw 6；The other end of fixinig plate is equipped with the threaded shank for star-like nut
Divide mobile adjustment hole 9, the shape of adjustment hole is rectangle；It, first will be fixed when needing luggage frame 1 being fixed on luggage carrier
Two fixinig plates of clip are each passed through connecting screw 6, and the fixing being made of at this time two fixinig plates is U-shaped, will be U-shaped
Fixing is set on luggage carrier, then by star-like nut 5 through the adjustment hole of two fixinig plates, according to the size adjusting of luggage carrier
Until fixing 4 is locked completely, luggage frame 1 is strongly secured on luggage carrier for the position of star-like nut 5.Connect cross bar 6
It is the important load bearing component for connecting luggage frame 1 and luggage carrier, which can be used the bar of nonmetallic high molecular material, pass through number
Control machining center milling shaping.Luggage net 2 can be by the binding straps of nonmetallic materials or the connect band with cementability is fixed
Onto luggage frame 1, luggage net 2 is the net structure being woven into nylon rope according to certain rule.Log-periodic antenna 3 passes through
The binding strap of nonmetallic materials or the connect band with cementability are fixed on luggage net 2, and log-periodic antenna 3 is secondary by length by eight
Square array is assembled to be formed, and is fixed on respectively on the long cross direction of luggage net 2.The making of log-periodic antenna 3, using height
Warm shielding line carries out calculation simulation analysis according to antenna technology parameter and obtains a result, and passes through soldering by antenna oscillator and feeder line
It is welded to connect.To avoid electromagnetic interference of the metal material to positioning antenna, entire police vehicle positioning antenna assembly is secondary right except eight
Beyond one number time antenna 3, remaining structure division uses the nonmetallic composite of high intensity.All log-periodic antennas 3
Oscillator is fixed on luggage net 2, and luggage net 2 links together with luggage frame 1, entire luggage frame 1 again by fixing 4 with
Star-like nut 5 is adjusted, fixation is connected with luggage carrier, it is police so as to constitute together with luggage carrier is directly fixed on roof
Vehicle positioning antenna assembly.
The police vehicle positioning antenna assembly of technical scheme mainly presses rectangle by eight gain directional antennas
Battle array is assembled to be formed, wherein per slave antenna unit using orientation high-gain log-periodic antenna, log-periodic antenna is a kind of width
Band antenna, the antenna have many advantages, such as high gain, high directivity, front and rear than big, and the oscillator of log-periodic antenna is by a uniform biography
Defeated line feed, transmission line cross feed between adjacent symmetric oscillator, working band is very wide, 10 times or more reachable, Er Qie
In entire wave band, spatial pattern ai is substantially unrelated with wavelength.Joined in design by the scale parameter of optimization design oscillator with interval
Number, with reference to the design feature of police vehicle positioning antenna, selects the data such as the length of oscillator, the spacing of oscillator and thickness.
For existing police vehicle positioning antenna, frequency range is narrow in actual use, antenna gain effect is bad, day
Line entirety is not hidden, is easy to the shortcomings of exposed, and technical scheme can meet the requirement of existing weaponry and equipment system, and
Enormously simplify the load of roof, effectively reduce vehicle advance in caused by external antenna wind load, shape be easy to hidden, work
The covering of working frequency scope is wider, meets the requirement of all communication systems processed, superior performance, and significant effect is public security department
Effectively carry out investigation to provide convenience.
The foregoing is merely the preferred embodiments of invention, are not intended to limit the invention, all spirit in the present invention
Within principle, any modifications, equivalent replacements and improvements are made should all be included in the protection scope of the present invention.
