Description
Technical field
The present invention relates to technical field of communication equipment, especially relate to a kind of novel ceiling antenna.
Background technology
Ceiling mount antenna is the principal antenna type for quorum sensing inhibitor in indoor distributed system, the direct influential system efficiency of its performance, communication quality and network investment.Ceiling mount antenna is generally made up of radiant body, feeder line and ground plate, and wherein, ground plate connects with body of wall, and radiant body is in the below of ground plate, and feeder line is connected with radiant body through ground plate.According to actual needs, radiant body can adopt perpendicular polarization radiant body or horizontal polarization radiant body, also can be that perpendicular polarization radiant body and horizontal polarization radiant body adopt simultaneously.
At present, the radiant body of traditional ceiling mount antenna adopts metal connecting piece to be fixed on ground plate mostly.As shown in Figure 1, the perpendicular polarization radiant body 1' of this bipolar omni-directional ceiling antenna is riveted on ground plate 3' by short-contact metal sheet 2'; As shown in Figure 2, the horizontal polarization radiant body 4' of this bipolar omni-directional ceiling antenna is fixed on Antenna baseplate 6' by metal joint pin 5'.Perpendicular polarization radiant body or often have several connectors conducted electricity between horizontal polarization radiant body and ground plate, as rivet, joint pin etc.But because the structural member such as rivet, joint pin is by the impact of self material, the resistance of each rivet, joint pin is difficult to accomplish identical, cause the perpendicular polarization radiant body in the same antenna or the resistance between horizontal polarization radiant body and ground plate indefinite.Affect by this, signal is when feeder line transfers to perpendicular polarization radiant body, and signal stabilization is difficult to ensure.
For this reason, a kind of novel ceiling antenna is needed.
Summary of the invention
To the object of the present invention is to provide between a kind of radiant body and ground plate and the novel ceiling antenna of constant, the steady signal transmission of resistance between feeder line and ground plate.
To achieve these goals, the present invention adopts following technical scheme:
A kind of novel ceiling antenna, comprises radiant body, feeder line and ground plate, especially, also comprises the holder and locking piece be made up of insulating material; Described holder comprises connecting ring, some fasteners and some joint pins; Described fastener is arranged on the side of connecting ring; Described joint pin is arranged on the opposite side of connecting ring; Described connecting ring, fastener and joint pin are connected and fixed; Described locking piece is provided with feeder line via hole; Described locking piece and described joint pin link together; Radiant body is connected with holder by fastener; Ground plate is between joint pin and locking piece, ground plate is provided with feeder line through hole.
Feeder line comprises inside conductor and outer conductor, is provided with insulating barrier between inside conductor and outer conductor.
Radiant body can perpendicular polarization radiant body, also can be horizontal polarization radiant body.
Principle of the present invention is as follows:
The fastener of holder buckles in radiant body, and radiant body and holder are interfixed; Locking piece and joint pin link together, and ground plate is fixed between holder and locking piece.
Feeder line passes hole and holder through the feeder line via hole of locking piece, the feeder line of ground plate successively, and inside conductor and the radiant body of feeder line are interconnected, and outer conductor and the ground plate of feeder line are interconnected.Because feeder line is directly connected with radiant body, for same antenna, the resistance of feeder line and radiant body connecting place can't change, and the holder insulation of fixing radiant body, therefore, signal is when feeder line transfers to radiant body, and signal stabilization is good.
The inside conductor of feeder line is preferably welded to connect with radiant body, and the outer conductor of feeder line is preferably welded to connect with ground plate, and like this, in same antenna, feeder line and radiant body, resistance between feeder line and ground plate will keep constant, and signal transmission can not be affected.
Joint pin is preferably provided with screwed hole, and locking piece and joint pin are linked together by screw.
Connecting ring is preferably in taper, and the middle part of connecting ring is provided with emptiness avoiding hole.Utilize emptiness avoiding hole, radiant body is when especially perpendicular polarization radiant body is fixed on holder, and radiation physical efficiency is positioned as close to holder, makes fastener just can fix radiant body well without the need to long, thus saves the making material of holder.
Fastener is preferably made up of two resilience parts, is reserved with avoiding hollow groove between two resilience parts; Resilience part is also provided with the buckle portion for fastening radiant body.When fastener is through fixing hole, owing to being provided with avoiding hollow groove between two resilience parts, two resilience parts can be extruded to be drawn close, thus passes through fixing hole; Fastener is through after fixing hole, and the resilience of resilience part, makes the buckle portion of resilience part be fastened on radiant body, thus make radiant body be fixed on holder.
For avoiding in use feeder line wobble effects signal, locking piece is preferably formed with sleeve; Feeder line via hole is formed at the inside of sleeve longitudinal direction.Feeder line is by feeder line via hole through after locking piece, and partial line is known from experience and is fixed in sleeve, even if feeder line rocks, this partial line body also there will not be and significantly rocks, thus ensures the quality of Signal transmissions.Further, sleeve is formed with some calvus away from one end of ground plate; Also comprise one for tightening up the nut cap of described calvus; Described nut cap and described sleeve are threaded connection.Nut cap is arranged on sleeve, and the distance entering sleeve along with nut cap is deepened, and nut cap can calvus on continuous compression sleeve, makes calvus be engaged the feeder line entered through feeder line via hole, feeder line is firmly arranged in sleeve.
Ground plate can be the compoboard that pcb board or metallic plate and nonmetal medium combine.The one side of ground plate is provided with covers copper and the reflecting surface formed, and the another side of ground plate is provided with outer conductor weld part; Reflecting surface and the conducting of outer conductor weld part; Reflecting surface backward radiation body.The outer conductor weld part that is welded on of feeder line and ground plate completes, like this, and the stable connection of feeder line and ground plate, and without the need to coated many copper on ground plate.
Structure of the present invention is simple, and realize insulation by holder between radiant body with ground plate and be connected, feeder line and radiant body, feeder line and ground plate are welded to each other, and make feeder line and radiant body, resistance between feeder line and ground plate keeps constant, stable signal transmission is strong.
