Feed wire rod, design is many.Non-balanced transmission line and balanced transmission line is selected to have following difference: (1) antenna to have best
Performance, it is necessary to have " electric current of balance ", in balanced transmission line, transmission is exactly the electric current balanced, it is possible to preferably solve feed
Unbalanced phenomenon, makes the directional diagram of dual polarized antenna 1 realize preferable symmetry.And the electric current of non-balanced transmission line is uneven
Weighing apparatus, directly use non-balanced transmission line feed, the current imbalance on antenna can be made, directional diagram cannot reach best effective
Really, if but the impact that brings of this uneven feed is not the biggest, it is also possible to use non-balanced transmission line;(2) non-equilibrium transmission
Line current is unbalanced, non-equilibrium current can be changed into balanced balanced current by " balun " this element, but add bar
Human relations mean become complicated so that design and need to increase research and development and Material Cost;(3) Unbalanced line feeding scheme is simple, material
Low cost, shield effectiveness are best, are suitable for radio-frequency (RF) energy transmission.

Limited by the main polarization direction of electric field of two dipole antenna units with direction, therefore director position and direction are set
Limited and little to the performance and index contribution improving dual polarized antenna.
Owing to the radiation scope of horizontally-polarized antenna unit 101 and vertical polarized antenna unit 102 is big, therefore they
Director all can be set in radiation scope.At least one first director 50 may be used for strengthening horizontally-polarized antenna unit
101 electric waves launched to the first director 50 direction, at least one second director 60 may be used for strengthening vertical polarized antenna
The electric wave that unit 102 is launched to the second director 60 direction.By arrange at least one first director 50 and at least one the
Two directors 60, such that it is able to improve the gain of dual polarized antenna 1, the bandwidth of expansion dual polarized antenna 1 further.
Advantageously, as shown in Fig. 1, Fig. 4 and Fig. 6, the first director 50 is two, two the first director 50 relative levels
First lateral symmetry axis L2 of polarized antenna elements 101 is symmetrical, and the second director 60 is two, two the second director 60 phases
This second lateral symmetry axisymmetrical to vertical polarized antenna unit 102.
At least one the first director 50 and at least one second director 60 may be located in same level, it is also possible to
It is positioned on different horizontal planes.When the first director 50 is multiple, multiple first directors 50 can be arranged, also at interval
Can link into an integrated entity.When the second director 60 is multiple, multiple second directors 60 can be arranged at interval, it is also possible to
Link into an integrated entity.
As shown in Fig. 1, Fig. 4 and Fig. 6, advantageously, each in the first director 50 and the second director 60 can be
Circle, and the first director 50 can be provided with relative the first sector notch and second with in each in the second director 60
Sector notch.
It should be noted that the ginseng such as the first director 50 and the shape of the second director 60, quantity, size, position, spacing
Number can be adjusted realizing optimal performance according to antenna index request.
As shown in Fig. 1, Fig. 5 and Fig. 6, dual polarized antenna 1 farther includes load plate 70, and load plate 70 is located at horizontal polarization
Between antenna element 101 and vertical polarized antenna unit 102.Load plate 70 and the plane at horizontally-polarized antenna unit 101 place
The angle of (i.e. the plane at the first noumenon 1014 place) is more than 0 degree and is less than or equal to 90 degree, load plate 70 and vertical polarized antenna
The angle of the plane (plane at the i.e. second body 1024 place) at unit 102 place is more than 0 degree and less than or equal to 90 degree.
What existing dual polarized antenna was arranged is flatly arranged with slide glass.Dual polarized antenna 1 according to embodiments of the present invention
By arranging to become to preset with the plane at horizontally-polarized antenna unit 101 place and the plane at vertical polarized antenna unit 102 place
The load plate 70 of angle, thus it is possible not only to improve further the gain of dual polarized antenna 1, and can realize better
Impedance matching, manifests better directional diagram.
As shown in Fig. 1, Fig. 5 and Fig. 6, load plate 70 is four.Horizontally-polarized antenna unit 101 and vertical polarized antenna list
Four lines of rabbet joint, four load plate 70 are had to be located at correspondingly in these four lines of rabbet joint between unit 102.
Advantageously, as shown in Fig. 1, Fig. 5 and Fig. 6, load plate 70 is perpendicular to the plane at horizontally-polarized antenna unit 101 place
(such as horizontal plane), and load plate 70 is perpendicular to the plane (such as horizontal plane) at vertical polarized antenna unit 102 place.
It should be noted that the shape of load plate 70, quantity, size, position, adjacent load plate 70 the parameter such as spacing can
It is adjusted realizing optimal performance according to antenna index request.
In describing the invention, it is to be understood that term " " center ", " longitudinally ", " laterally ", " length ", " width ",
