Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Refer to Fig. 1 and Fig. 2, what Fig. 1 and Fig. 2 disclosed is a kind of modified model gps antenna, the protecgulum 500 comprising ceramic antenna 100, radome 200, pcb board 300, holding wire 400 and be located at outside described radome 200.Described protecgulum 500 is made of plastics.Be provided with groove 510 outside described protecgulum 500, outside refers to the side of described protecgulum 500 away from described radome 200.Be provided with magnet pot cover 520 in described groove 510, in described magnet pot cover 520, be provided with ndfeb magnet 530.Described magnet pot cover 520 is made up of metal material, for being gathered by the magnetic line of force, strengthens the suction of described ndfeb magnet 530.The upper surface of described ndfeb magnet 530 is higher than the outer surface of described protecgulum 500, and like this, the suction of the described ndfeb magnet 530 exposed strengthens greatly, is not easy to come off when therefore described ndfeb magnet 530 is adsorbed on magnetic bodies.Deck portion outside described protecgulum 500 covers double faced adhesive tape 540, avoids the described ndfeb magnet 530 exposed being covered interior and affecting suction, and the area coverage of described double faced adhesive tape 540 reduces, and materials also reduce, and also a saving cost of manufacture.The upper plane of described double faced adhesive tape 540 is higher than the upper plane of described ndfeb magnet 530, and like this, when substrates, first object contacts described double faced adhesive tape 540, fully fits with described double faced adhesive tape 540; Not so, if non-magnetic object first contacts described ndfeb magnet 530 contact described double faced adhesive tape 540 again, can paste not tight on the contrary, easily come off.
The one side of described pcb board 300 is electrically connected with described ceramic antenna 100.The another side of described pcb board 300 is printed with low noise amplifier, and in order to shield the signal of low noise amplifier, the one side being printed with low noise amplifier at described pcb board 300 arranges radome 200, and is fixedly connected with described radome 200.Described radome 200 is made up of stainless steel, zinc-plated steel band or foreign copper-nickel alloy.Described radome 200 and described pcb board 300 can be that the mode by extruding or welding is connected, and the mode that also can have same effect by other is implemented.Described radome outer rim is provided with gum cover 210.Described holding wire 400 one end and described pcb board 300 are electrically connected, and the other end is connected with connector 420.Described holding wire 400 comprises cable and connecting line, in described connecting line is wrapped in by described cable.
In the present embodiment, in order to protect described parts such as ceramic antenna 100 grade, also comprise bonnet 600, described bonnet 600 is made of plastics.Described ceramic antenna 100, radome 200 and pcb board 300 are included by described bonnet 600, and described bonnet 600 coordinates with protecgulum 500 and is fixedly connected with, and the outer rim of described protecgulum 500 is slightly less than the inner edge of described bonnet 600.Cover in 600 in the rear and be provided with the groove 610 coordinated with described ceramic antenna 100 and pcb board 300, for fixing the position of described ceramic antenna 100 and pcb board 300.The side covering 600 is in the rear provided with through hole 620, and described holding wire 400 passes described through hole 620 and is connected with described connector 420.Described holding wire 400 is provided with sealing ring 410 with the junction of described through hole 620.Described sealing ring 410 pollutes the parts such as described ceramic antenna 100 for preventing liquid, wet gas and other corrosive substances.Described sealing ring 410 can be made by the flexible material such as silica gel or rubber.
Owing to being provided with groove 510 outside protecgulum 500, in described groove 510, be provided with magnet pot cover 520, in described magnet pot cover 520, be provided with ndfeb magnet 530.The maximum magnetic energy product of described ndfeb magnet 530 is larger than general magnet, and therefore magnetic force is stronger.Deck portion outside described protecgulum 500 covers double faced adhesive tape 540, and in this structure, ndfeb magnet 530 exposes, and suction strengthens, and can coordinate be pasted in object with double faced adhesive tape 540, and reduces due to the area coverage of double faced adhesive tape 540, cost of manufacture reduction.
During use, the utility model is pasted on required object, described connector is connected with the connector of cooperation.During ceramic antenna Received signal strength, be electric field by electrode by the electromagnetic wave induction transmitted in the air exactly, generate high-frequency signal voltage, be sent to next module and carry out signal transacting.When ceramic antenna transmits, by electrode, the high-frequency electric field formed between antenna and ground is become electromagnetic wave exactly, thus can launch and pass ripple to a distant place.Wherein, described pcb board includes amplifying circuit and filter circuit.
Obviously, those skilled in that art can carry out various change and modification to the utility model and not depart from spirit and scope of the present utility model.Like this, if these amendments of the present utility model and modification belong within the scope of the utility model claim and equivalent technologies thereof, then the utility model is also intended to comprise these change and modification.
