[embodiment]
With reference to figure 1, the electric wire that one embodiment of the invention provides comprises phase shifter, this phase shifter comprises base plate 4, cover plate (Fig. 1 does not show), is installed to the mounting medium 3 of base plate 4, is installed to mounting medium 3 the air strip line mechanism inner wire 2 between base plate 4 and cover plate, also comprise at least one phase-shifting unit, each phase-shifting unit comprises slip medium block 1.
Referring to figs. 2 to Fig. 4, slip medium block 1 comprises main part and the some cantilevers that stretch out from a side of main part.The end of cantilever has clip slot and accommodates air strip line mechanism inner wire 2 and slip medium block 1 and can slide along the Width of air strip line mechanism inner wire 2.Preferably, slip medium block 1 has 3 cantilevers, is E shape, in the projection of base plate 4, is E shape.When slip medium block 1 can slide along air strip line mechanism inner wire 2, phase shifter changes.Should recognize, slip medium block 1 also can have the cantilever of 2 or other quantity.
Preferably, the degree of depth of clip slot (along the size of the Width of air strip line mechanism inner wire 2) is equal to or greater than the width of air strip line mechanism inner wire 2.So, air strip line mechanism inner wire 2 can be housed in this clip slot along Width integral body, the medium block 1 that makes to slide has larger sliding distance with respect to air strip line mechanism inner wire 2, thereby has improved the performance index such as frequency range, gain, angle of declination precision, upper Sidelobe Suppression.
Between adjacent cantilever, form groove.Preferably, the degree of depth of groove (along the size of the Width of air strip line mechanism inner wire 2) is equal to or greater than the width of air strip line mechanism inner wire 2.So, air strip line mechanism inner wire 2 can be housed in this groove along Width integral body,, at ad-hoc location, be equivalent to only have some sections of discrete cantilevers clamping air strip line mechanism inner wire 2, and the main part of slip medium block 1 does not clamp air strip line mechanism inner wire 2, thereby the performance index such as frequency range, gain, angle of declination precision, upper Sidelobe Suppression have been improved.
Preferably, the free end of described cantilever has the size diminishing.In the present embodiment, the size of a part of cantilever is linear narrowing (cantilevers at medium block 1 two ends of for example sliding), and a part of cantilever is not strict linear narrowing but at ad-hoc location, by step, realizes size and dwindle).So, the groove forming between adjacent cantilever, has maximum size by the position at cantilever openend.
With reference to figure 4, to Fig. 7, phase-shifting unit also comprises the cable welding seat 5 that is fixed to base plate 4, and cable welding seat 5 has support level for carrying cable, the cable inner conductor 8 of cable and 2 welding of air strip line mechanism inner wire.The cable outer conductor 7 of cable and 5 welding of cable welding seat.In the present embodiment, the support level of cable welding seat 5 is the through holes that are formed at cable welding seat 5, and through hole current supply cable passes.Cable comprises the cable outer conductor 7 that is wrapped in medium 9 in medium 9 in the cable of cable inner conductor 2 and parcel cable, one end welding of cable outer conductor 7 and through hole, and in cable, medium 9 and cable inner conductor 2 are through through hole.
Cover plate 6 is connected with base plate 4 conductions by cable welding seat 5.The upper and lower cover plates of air strip line connects by the upper and lower short circuit of cable welding seat, forms the required cavity body structure of electrical transmission.
