Abstract
The invention discloses a leaky coaxial cable with a reflecting surface. The leaky coaxial cable with a reflecting surface comprises: a leaky coaxial cable, a reflecting surface and a fixed support. The leaky coaxial cable is arranged between the reflecting surface and the fixed support. Two end points of the fixed support are connected to the reflecting surface. The reflecting surface is a curved surface structure or a plate surface structure. By using the leaky coaxial cable with the reflecting surface of the invention, radiation field strength of one side of the leaky coaxial cable can be substantially reinforced, which means that electromagnetic wave intensity in a leaky coaxial cable working area can be increased. Through adjusting the length of the fixed support, leaky coaxial cable radiation field strength can be controlled so that the leaky coaxial cable can reach an optimal working state.

Technical field:
This patent relates to the communications field, relates in particular to a kind of leaky coaxial cable with reflecting surface.
Background technology:
Leaky coaxial cable is a kind of feed line that disposes continuous slot array; Its part energy can evenly, stably be radiated outside the space with the form of radiated wave; Another part energy still in the inside of leaky coaxial cable along axial transmission, so leaky coaxial cable has the function of transmission line and radiating antenna simultaneously.The most important performance index of leaky coaxial cable are vertical transmission attenuation and coupling loss, and vertically transmission attenuation is an important indicator of describing the leaky coaxial cable internal transmission electromagnetic energy extent of damage, and vertically transmission attenuation is more little, and then transmission range is far away more; And but coupling loss is to describe the overall target of leaky coaxial cable amount of radiation and quantities received, and coupling loss is more little, and then radiation field intensity is strong more.
Then vertically transmission attenuation is big more for general coupling loss more little (sewing more), and on the contrary, then vertically transmission attenuation is more little for coupling loss bigger (sewing few more).Under the constant situation of transmission range; Want to increase the radiated electric field of leaky coaxial cable; Except increasing input power or utilizing the multiplying arrangement; Method commonly used is the collocation method that continues of the leaky coaxial cable of several kinds of different coupling losses, yet connecting method can increase the use of connector and wire jumper, brings unnecessary Insertion Loss.
Summary of the invention:
The objective of the invention is in order to overcome above deficiency, a kind of radiation field intensity that can significantly strengthen leaky coaxial cable one side is provided, promptly increase a kind of leaky coaxial cable of leaky coaxial cable service area electromagnetic intensity with reflecting surface.
The object of the invention is realized through following technical scheme: comprise leaky coaxial cable, reflecting surface and fixed support; Leaky coaxial cable places between reflecting surface and the fixed support; Support bracket fastened two end points are connected on the reflecting surface negative camber, and reflecting surface is curved-surface structure or plate face structure, and leaky coaxial cable is that leaky coaxial cable is used in the communication of outer conductor fluting; Reflecting surface is the plastic plate that metal film is covered on metal curved surface or surface; Be used for electromagnetic wave is reflected and focuses on, a side radiated electromagnetic wave of leaky coaxial cable reflexed to opposite side, to strengthen the signal strength signal intensity of service area; Fixed support is used for reflecting surface is fixed on leaky coaxial cable; Fixed support is the variable-length support, through regulating support bracket fastened length, can realize the change of reflecting surface and leaky coaxial cable spacing; On leaky coaxial cable, have and sew slotted eye; Reflecting surface is fixed on leaky coaxial cable vertically along the line back to the direction of sewing slotted eye, on leaky coaxial cable, has and sews slotted eye, and it is vertically along the line over against the direction of sewing slotted eye that reflecting surface is fixed on leaky coaxial cable.
The present invention compared with prior art has the following advantages:
On leaky coaxial cable, add reflecting surface, can significantly increase the electromagnetic intensity of leaky coaxial cable service area; Under the constant prerequisite of input power, can strengthen the radiation field intensity of service area one side; Through adjusting support bracket fastened length, promptly adjust the distance of leaky coaxial cable and reflecting surface, select the shape and size of suitable reflecting surface simultaneously, can control the leaky coaxial cable radiation field intensity, make leaky coaxial cable reach optimum Working.
