Embodiment
Below in conjunction with the accompanying drawings and embodiment the present invention will be further described, but to embodiments of the present invention notIt is limited to this.
Embodiment
Shown in reference picture 1, Fig. 1 is the dimensional structure diagram of new medium block of the present invention.The new medium block includes the He of substrate 3Dielectric-slab.
The one side of substrate 3 is provided with boss 31, and boss 31 is provided with some connecting poles 32, wherein some connecting poles 32 are spacedIt is arranged on boss 31.Specifically, some connecting poles 32 are used to substrate 3 being detachably arranged at pull bar 4, to cause pull bar 4With the connection of new medium block, the movement of new medium block is driven.
Dielectric-slab is arranged on the another side of substrate 3 and for adjusting wave beam.Dielectric-slab includes upper dielectric-slab 1 and lower JieScutum 2, upper dielectric-slab 1 and lower dielectric-slab 2 are disposed in substrate 3.Further, upper dielectric-slab 1 and lower dielectric-slab 2 are symmetricalIt is arranged in substrate 3.Wherein, upper dielectric-slab 1 and lower dielectric-slab 2 are opened provided with the opening of at least two first 11 and at least two secondMouth 12.The opening of at least two first 11 and the opening of at least two second 12 are provided with upper dielectric-slab 1 and lower dielectric-slab 2, can be withSo that the radiating effect of dielectric-slab is improved.Preferably, the opening of at least two first 11 and the opening of at least two second 12 are arranged at intervalsOn upper dielectric-slab 1 and lower dielectric-slab 2.
Preferably, the opening of at least two first 11 is symmetrical arranged.Equally, the opening of at least two second 12 is symmetricly set at leastBetween 2 first openings 11.It should be understood that when medium block works, certain heat is produced, in upper dielectric-slab 1 and lower dielectric-slab 2Upper setting at least two first opening 11 and the opening of at least two second 12, add the surface area of medium block, contribute to heatDistribute.
