Abstract
The utility model discloses a double polarization all microstrip directional antenna for mobile communication basic station, including: a radome, a main reflector, an auxiliary reflector, the dipoles, the decoupling units, a microstrip transmission line substrate, a top cover and a bottom cover. The main reflector is foldablely arranged in the slide groove of the radome; the decoupling modules is placed amongst the dipoles; each dipole and decoupling unit are welded on the microstrip transmission line substrate; the internal components of the antenna are all RF materials instead of metal material and coaxial cable. The directional antenna production process of such structure is simple and the antenna has light weight, low cost, stability and reliability.
Description
The full microstrip directional antenna in the utility model dual polarization mobile communication base station belongs to the key equipment of a kind of GSM, cdma mobile communication base station equipment antenna-feedback system.
At present, the base station directional antenna that base station equipment antenna-feedback system directional antenna all adopts German Kai Shilin and U.S. Andrew Corporation to produce in the existing mobile communication construction of mobile communication carriers such as domestic China Mobile, CHINAUNICOM, traditional standard securing member and special welding mounting technology technology are adopted in its primary structure design: main antenna reflector and radome assembly adopt securing member and macromolecule silicon waterproof and sealing material; Inner part adopts metal material to form through punch process and surface treatment; Be electrically connected between each unit and adopt the coaxial cable feedback to connect, complex manufacturing, particularly connect by coaxial cable feedback, joint is many, solder joint is many, operation is many and since antenna be operated in microwave band, be to adopt special welding procedure, solder joint physical dimension to require quite strict, high, the difficult control of welding quality of technical difficulty again.Inner part is again to adopt metal material, and product weight is also heavier, and production cost is than higher.
The purpose of the invention is to provide a kind of fastener-free, production technology is simple, production cost the is low full microstrip directional antenna in high-quality dual polarization mobile communication base station, and it can overcome the deficiency of above-mentioned prior art.
For achieving the above object, for the full microstrip directional antenna in the dual polarization mobile communication base station of forming by radome, main reflector, subreflector, dipole, decoupling unit, microstrip transmission line substrate and loam cake, bottom, its main reflector flanging is disposed in the unstressed chute of radome, the cancellation securing member; Subreflector is mounted on the left and right sides of radome; The decoupling unit is placed between the dipole; Each dipole and decoupling unit all adopt common tin welder skill to be welded on the microstrip transmission line substrate; Substrate sticking is on the panel of main reflector; Inner each element of antenna all adopts RF panel material alternative metals material and coaxial cable.
After adopting said structure since main reflector with radome combination cancellation securing member, between the two become free mated condition, well solved height distortion, the bending that difference variation produced under the adverse circumstances out of doors of the different internal stresss of different materials, breaking etc. influence the problem of antenna performance index, anti-functional, the most securing member of saving and encapsulant, minimizing spillage of material and the operation of intaking; Inner each element of antenna all adopts RF panel material alternative metals material and coaxial cable, effectively solves the technology difficult problem that the coaxial cable feedback connects, and alleviates antenna weight, favourable communication engineering high-altitude installation exercise greatly, effectively alleviates the load of antenna tower; This antenna coupling extremely son is connected employing common tin welder skill with the microstrip transmission line contact, solder joint is few, welding procedure is simple; This production assembly technology is simple, product reliability, good stability, can improve the quality of products and production capacity.
Below in conjunction with the drawings and specific embodiments the full microstrip directional antenna in the utility model dual polarization mobile communication base station is described in further detail.
Fig. 1 is the agent structure plane graph of the full microstrip directional antenna in the utility model dual polarization mobile communication base station
Fig. 2 is the agent structure profile of this antenna
Fig. 3 is the section of structure of unstressed chute shown in Figure 2
As attached illustrated in figures 1 and 2, this antenna loam cake 1, bottom 8 are installed in the top and the bottom of antenna by uvioresistant, anti-aging injection molding; Radome 2 uses extruding-out process to draw out unstressed cunning poor 11 by same plastic material; Main reflector 3 adopts metal material flanging processes, flanging to be disposed in the unstressed cunning poor 11 of radome 2.Subreflector 9,10 adopts metal forming to be mounted on the left and right sides of radome 2, and dipole 4 adopts RF plate Precision Machining, 90 degree that intersect are installed and formed; Decoupling unit 5 adopts the above-mentioned material processes, is placed in coupling extremely between the son 4.Decoupling unit 6 adopts same material technology processing, 90 degree that intersect are installed and formed, are placed in coupling extremely between the son; Each dipole 4 and each decoupling unit 5,6 are installed and are welded on the microstrip transmission line substrate 7, and the microstrip transmission line feedback on the substrate 7 connects each dipole 4, forms the dipole submatrix.Then substrate 7 usefulness colloidal materials are sticked on main reflector 3 panels, realize no standard fasteners assembling.Each dipole 4 of antenna is connected employing common tin welder skill with the microstrip transmission line contact, solder joint is few, welding procedure is simple.
