The dipole antenna comprises a printing plate, two surfaces of the printing plate are symmetrically provided with metal transmission lines of good conductors, the metal transmission lines form two arms of the dipole antenna, a microstrip transmission line, and two microstrip baluns, the microstrip transmission line is a double-transmission-line structure, two arms of the dipole antenna and two microstrip baluns are respectively and symmetrically arranged at two ends of the microstrip transmission line, the microstrip baluns are in the shape of right angle trapezoids, and the lower bottoms of the trapezoids are connected to the microstrip transmission line. The microstrip printing dipole antenna is advantaged by light weight, small size, low cost, convenient integration and array composition, and the application demand of miniaturization of electronic products is met.
Description
Technical field
The present invention relates to communication technical field, particularly relate to a kind of microband printing dipole antenna.
Background technology
Dipole antenna is used for launching and receiving the signal of fixed frequency.Although all using sky, broadband in measurement at ordinary times
Line, but be required for using dipole antenna in the measurement of site attenuation and antenna factor.Along with people to communication quality and are led to
The integrated requirement of letter equipment constantly strengthens.As communication equipment subassembly, antenna is also required to higher performance to meet communication system
The needs of system.Now, a kind of printed dipole antenna occurred, this antenna is to be printed on dipole on thin-medium substrate, its
Processing lightweight, easy and comparatively wide bandwidth and advanced purity are provided, the structure of this antenna i.e.: with printed board for
Holding, one side arranges dipole, and another side arranges coupling feeder line.
Electronic product of today mostly develops toward the direction of miniaturization, but existing printed dipole antenna size is relatively
Greatly, therefore need that a kind of volume is little, the printed dipole antenna of compact conformation badly.
Summary of the invention
For the deficiencies in the prior art, it is an object of the invention to provide a kind of microband printing dipole antenna, volume is little,
Compact conformation, meets the demand that miniaturization of electronic products uses.
In order to achieve the above object, the present invention is by the following technical solutions:
A kind of microband printing dipole antenna, this dipole antenna includes galley, and the two sides symmetry of described galley is with good
The metal transmission line of conductor, described metal transmission line constitutes two arms, microstrip transmission line and two of described dipole antenna
Microstrip balun, described microstrip transmission line is pairs of transmission line structure, and two arms of described dipole antenna, two microstrip baluns are respectively
Being symmetricly set in the two ends of microstrip transmission line, the most trapezoidal and trapezoidal the going to the bottom of described microstrip balun is connected to microstrip transmission line
On.
Further, described microstrip transmission line is positioned at the end on galley surface is wireless distributing point.
Dipole antenna is a symmetrical structure, and the feed current on transmission line must be symmetrical, if using
Coaxial line structure, because coaxial line internal and external conductor asymmetric so electric current on antenna also will not be symmetrical, thus affect antenna
Performance.Therefore, the present invention designs the microstrip transmission line that transmission line is pairs of transmission line structure, because the electric current of pairs of transmission line is right
Claim distribution, so the electric current of antenna is also symmetrical；Further, in order to be further ensured that the balance of electric current on dipole antenna,
Connecting at the two ends of microstrip transmission line and have microstrip balun, it can realize the uneven conversion to balance.
This reality micro-strip has the beneficial effect that with novel:
This microband printing dipole antenna have lightweight, volume is little, low cost, the integrated and advantage of composition array of being easy to, full
The demand that foot miniaturization of electronic products uses.
Accompanying drawing explanation
Fig. 1 is the structural representation of the microband printing dipole antenna of the present invention；
Fig. 2 is present invention schematic diagram in surface current direction when working.
In Fig. 1,1-galley, two arms of 2-dipole antenna, 3-microstrip transmission line, 4-microstrip balun, feedback that 5-is wireless
Electricity point.
Detailed description of the invention
The invention will be further described to combine accompanying drawing below by embodiment.
As it is shown in figure 1, a kind of microband printing dipole antenna, this dipole antenna includes galley 1, the two of galley 1
Face symmetry is with the metal transmission line of good conductor, and metal transmission line constitutes two arms 2 of described dipole antenna, micro-strip transmission
Line 3 and two microstrip baluns 4, microstrip transmission line 3 is pairs of transmission line structure, 2, two micro-strip of two arms of described dipole antenna
Balun 4 is respectively symmetrically the two ends being arranged at microstrip transmission line 3, connection that what described microstrip balun 4 was the most trapezoidal and trapezoidal go to the bottom
On microstrip transmission line 3.
It is wireless distributing point 5 that microstrip transmission line 3 is positioned at the end on galley 1 surface.
Pumping signal feed-in at wireless distributing point 5, is transferred to dipole sky through microstrip balun 4 and microstrip transmission line 3
On two arms 2 of line, surface current points to as shown in Figure 2: on microstrip transmission line 3, and the sense of current is contrary, thus without radiation
Electromagnetic wave；On two arms 2 of dipole antenna, the sense of current is identical, therefore can radiated electromagnetic wave.
