Therefore, whether can provide a kind of can solve automobile turnover parking garage and carwash time problem, can ensure that again broadcast receiver normally uses is the problem that those skilled in the art need solution badly.
Utility model content
In view of this, the utility model provides a kind of problem that can solve automobile turnover parking garage and carwash, can ensure that again the vehicle-mounted radiofrequency signal symmetrical dipole that broadcast receiver normally uses receives soft board.
To achieve these goals, the utility model provides following technical scheme:
A kind of vehicle-mounted radiofrequency signal symmetrical dipole receives soft board, and comprising: body soft board, wherein said body soft board is provided with front and back; Be printed on the symmetrical dipole in described body soft board front by the mode of operplate printing circuit, wherein said symmetrical dipole is provided with three groups, is symmetrical dipole one, symmetrical dipole two, symmetrical dipole three; The coaxial cable be communicated with described symmetrical dipole by metal wire or metal wire; The signal of reception is transmitted signals to signal output point by described coaxial cable or metal wire by described symmetrical dipole.
Preferably, receive in soft board at above-mentioned vehicle-mounted radiofrequency signal symmetrical dipole, described body soft board is FET/PET flexible printed wiring soft board.
Preferably, receive in soft board at above-mentioned vehicle-mounted radiofrequency signal symmetrical dipole, the described body soft board back side is provided with gum, can be arranged on the required equipment used by the mode of gluing.
Preferably, receive in soft board at above-mentioned vehicle-mounted radiofrequency signal symmetrical dipole, often organize described symmetrical dipole and adopt mode arranged side by side to be symmetrically distributed in the both sides of described coaxial cable or metal wire.
Preferably, receive in soft board at above-mentioned vehicle-mounted radiofrequency signal symmetrical dipole, the contour structures of described symmetrical dipole is rectangle, and adopts 1/4 λ wavelength reception signal.
Known via above-mentioned technical scheme, compared with prior art, the utility model is by electric field and the radiation theory in magnetic field and the record principle of antenna oscillator, and will the reception Wavelength design of antenna be coordinated to become 1/4 λ wavelength, antenna oscillator is printed on flexible FET/PET soft board by the mode of operplate printing circuit, adopt symmetrical mode that three groups of symmetrical antenna oscillators are designed side by side on soft board simultaneously, reception is made to form superposition accumulative, there is guiding and amplify electromagnetic effect, the electromagnetic signal that antenna is received is stronger, reach the reception of antenna the best, and the gum that the soft board back side is arranged can be pasted onto the required place used in the mode of gluing.Therefore the utility model is not only installed simply, easy to use, and ensure that wireless normal use, antenna can be torn when need not worry turnover parking lot and garage simultaneously, and also handle antenna need not be taken off when carwash and screw on again, possess very strong practicality, and make car body cleanliness more dynamic beautiful attractive in appearance.
