Background technology
Car antenna application, in in-vehicle multi-media system, there is the equipment such as broadcast receiver, mobile TV, vehicle-mounted mobile communication, the working frequency range of these equipment is all different, need the antenna using corresponding different frequency range, such as FM working frequency range 87.5MHz-108MHz(CHINESE REGION), mobile TV is 470MHz-800MHz(CMMB TV).And traditional car antenna frequency band is narrow, frequency range is few, what can not realize different frequency range shares an antenna, cause the receptivity of radio, mobile TV poor, just need different antennas to receive if want performance to meet the requirements, this causes again the space shared by whole antenna system to increase, complexity increases, reliability decrease, cost improves, and is not well positioned to meet actual demand.
Utility model content
For the weak point existed in above-mentioned technology, the utility model provides that a kind of structure is simple, volume is little, cost is low and is easy to the vehicle-mounted all channel antenna of suitability for industrialized production.
For achieving the above object, the utility model provides a kind of vehicle-mounted all channel antenna, comprise helical antenna and feeder, described helical antenna is wound with first paragraph coil and second segment coil, the coil-span of described first paragraph coil is narrower than the coil-span of second segment coil, and the loop length of first paragraph coil is shorter than the loop length of second segment coil; One end of described feeder connects coaxial connector, and the other end of described feeder is provided with the heart yearn be connected with helical antenna, and the other end of this feeder is also provided with the gauze screen of unsettled placement.
Wherein, the surface of described feeder is also wrapped in and is connected with coaxial connector and is used for the gauze screen of the signal transmitting and receiving fixed frequency.
Wherein, the coil-span of described first paragraph coil is about 1mm and loop length thereof is about 15mm; The coil-span of described second segment coil is about 1.39mm and loop length thereof is about 215mm.
Wherein, the length of described feeder is about 750mm.
Wherein, described heart yearn is spirally connected by the screw of one end of nut and feeder is suitable;
Wherein, described feeder is made up of coaxial line.
The beneficial effects of the utility model are: compared with prior art, the vehicle-mounted all channel antenna that the utility model provides, helical antenna arranges two sections of coils, and the coil-span of first paragraph coil is more narrow than the coil-span of second segment coil, loop length is shorter, the design of this structure makes that the frequency band of car antenna is wider and frequency range is more, what realize different frequency range shares an antenna, avoid tradition to need different antennae to receive and cause that the space shared by whole antenna system increases, the appearance of the phenomenon such as complexity increase and reliability decrease; Meanwhile, the gauze screen of the other end of feeder is unsettled, and be not connected as ground connection with vehicle body, but keep insulating with vehicle body, this design further improves the receptivity of antenna.The utility model has that structure is simple, volume is little, dependable performance, cost are low and be easy to the features such as suitability for industrialized production.

Embodiment
In order to more clearly state the utility model, below in conjunction with accompanying drawing, the utility model is further described.
Refer to Fig. 1-2, the vehicle-mounted all channel antenna that the utility model provides, comprise helical antenna 10 and feeder 11, helical antenna 10 is wound with first paragraph coil 101 and second segment coil 102, the coil-span Z1 of first paragraph coil 101 is narrower than the coil-span Z2 of second segment coil 102, and the loop length L1 of first paragraph coil 101 is shorter than the loop length L2 of second segment coil 102; One end of feeder 11 connects coaxial connector 12, the other end of feeder 11 is provided with the heart yearn 101 be connected with helical antenna 10, and the other end of this feeder 11 is also provided with the gauze screen 112 of unsettled placement, the surface of feeder 11 is also wrapped in and is connected with coaxial connector and is used for the gauze screen 112 of the signal transmitting and receiving fixed frequency.Gauze screen 112 just changes the distribution of surface current, is equivalent to a covert dipole antenna.Unsettled gauze screen 112 is not connected with any, makes this gauze screen 112 different with traditional feeder mode, is not connected as ground connection in vehicle body, but keeps insulating with vehicle body.Feeder 11 is made up of coaxial line.
Compared to the situation of prior art, the vehicle-mounted all channel antenna that the utility model provides, helical antenna 10 arranges two sections of coils, and the coil-span Z1 of first paragraph coil 101 is more narrow than the coil-span Z2 of second segment coil 102, loop length is shorter, the design of this structure makes that the frequency band of car antenna is wider and frequency range is more, what realize different frequency range shares an antenna, avoid tradition to need different antennae to receive and cause that the space shared by whole antenna system increases, the appearance of the phenomenon such as complexity increase and reliability decrease; Meanwhile, the gauze screen 112 of the other end of feeder 11 is unsettled, and be not connected as ground connection with vehicle body, but keep insulating with vehicle body, this design further improves the receptivity of antenna.The utility model has that structure is simple, volume is little, dependable performance, cost are low and be easy to the features such as suitability for industrialized production.
In the present embodiment, the coil-span Z1 of first paragraph coil 101 is about 1mm and loop length L1 thereof is about 15mm; The coil-span of second segment coil 102 is about 1.39mm and loop length L2 thereof is about 215mm.The length of feeder 11 is about 750mm.Execution mode best in this case is the coil-span Z1 of first paragraph coil 101 is 1mm, and the loop length L1 of first paragraph coil 101 is 15mm; The coil-span of second segment coil 102 is 1.39mm, and the loop length L2 of second segment coil 102 is 215mm.Certainly; can change the spacing of two sections of coils and length according to the occasion of reality; as long as the spacing of guarantee first paragraph coil 101 and length, all than the large execution mode of second segment coil 102, all belong to the simple deformation to this case or conversion, fall in the protection range of this case.
In the present embodiment, heart yearn 101 is spirally connected with the screw 14 of one end of feeder 11 is suitable by nut 13; Certainly; in this case, helical antenna 10 and feeder 11 are not limited to by above-mentioned connected mode between the two; can also be other fixed forms such as bonding, clamping; if the change to above-mentioned connected mode; all belong to the simple deformation to this case or conversion, fall in the protection range of this case.
Be only several specific embodiment of the present utility model above, but the utility model is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection range of the present utility model.
