Description
Technical field
The utility model relates to a kind of electrical tilt antenna phase shift structure.
Background technology
Electrical tilt antenna also claims electrical tilt angle adjustable antenna, as its name suggests, its conventional relatively antenna, maximum characteristics be exactly can the Remote antenna angle of declination, thereby change the covering of antenna, improve network capacity and quality, play the effect of the network optimization.
The change of electric melody aerial lower inclination angle is to realize that by the phase difference that changes between each unit of antenna array the core component of realizing this function is exactly a phase shifter.The phase shifter of electrical tilt antenna all is independently parts at present, connection between it and each unit of antenna array all usefulness be the cable ways of connecting, this has just brought following shortcoming: one, use being connected of cable and phase shifter antenna element to be unable to do without junction block and welding procedure, this will inevitably bring very big difficulty to the passive intermodulation of control antenna.Two, the making of cable and installation wiring complex process.Three, the cost of antenna that used the bigger increase of cable.
The utility model content
Technical problem to be solved in the utility model provides a kind of cable that need not to use, thereby can better control the passive intermodulation of electrical tilt antenna, reduces the cost of electrical tilt antenna and the electrical tilt antenna phase shift structure of technology difficulty.
The technical solution adopted in the utility model is: electrical tilt antenna phase shift structure comprises the feeder line line segment, last floor, lower floor, described feeder line line segment is a strip line, described feeder messenger wire section is positioned at the floor, between the lower floor, with last floor, lower floor is formed the air strip lines configuration jointly, described feeder line line segment and last floor, also be provided with the phase shift medium between the lower floor respectively, described phase shift dielectric material is preferably the low loss tangent value, advanced low-k materials, described feeder messenger wire section is positioned at and partly is bent into square wave-shaped configuration between the power division node, the same also corresponding square wave-shaped configuration that is bent into of phase shift medium, and the preferred described phase shift medium that is bent into square wave-shaped configuration slightly is wider than the feeder line line segment of relevant position, by the phase shift medium on the plane that is parallel to the feeder line line segment along realizing influence with respect to moving of feeder line line segment to the transmission line phase place perpendicular to the feeder line line segment direction.
The beneficial effects of the utility model are: the utility model adopts the air strip lines configuration, no dielectric loss, and strip line has two floors up and down, and radiation loss is low; The phase shift medium is arranged on the internodal transmission line of power division, and is little to the impedance influences of transmission line, very little to the power division influence of each unit of antenna, thereby can guarantee the consistency of each angle of declination antenna pattern; Phase shift structure and feeding network of array antennas combination, the use of having saved cable has improved the passive intermodulation of antenna, has reduced cost and technology difficulty.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1, electrical tilt antenna phase shift structure comprises feeder line line segment 13, last floor 11, lower floor 12, feeder line line segment 13 is a strip line, feeder line line segment 13 is positioned at floor 11, between the lower floor 12, with last floor 11, the lower floor 12 common air strip lines configurations of forming, feeder line line segment 13 and last floor 11, also being provided with material between the lower floor 12 respectively is the low loss tangent value, the phase shift medium 2 of advanced low-k materials, as Fig. 2, shown in Figure 3, feeder line line segment 13 is bent on horizontal plane by parallel line segment 131,132 and connect the square wave-shaped configuration that the vertical linkage section 133 of two parallel lines constitutes, the upper section 21 at feeder line line segment 13 of same phase shift medium 2, part 22 also all corresponding being bent on horizontal plane in below by parallel line segment 211,212 and get in touch the square wave-shaped configuration that the vertical linkage section 213 between two parallel segments constitutes, and the phase shift medium slightly is wider than the feeder line line segment of relevant position.
Two phase shift media 21 up and down, 22 on the plane that is parallel to feeder line line segment 13 along perpendicular to feeder line line segment 13 directions during with respect to feeder line line segment linear mobile, along with phase shift medium 21,22 move into parallel segment 131,132 and up and down between the floor, linear delay has just taken place in the phase place of this section transmission line, when phase shift medium 21, during 22 whole immigrations, state as shown in Figure 2, this moment the amount of phase shift maximum, when the phase shift material all shifts out, state as shown in Figure 4, phase shift this moment medium 21, the phase place of 22 pairs of transmission lines does not have influence, thereby has realized the linear phase shift to this transmission line section.And, also can amount of phase shift be multiplied a plurality of such phase shift structures by on the feeder transmission section, arranging.
