1. vehicle-mounted overhead radio broadcasting reception antenna is made up of antenna pick-up dipole, utmost point low-noise wide-band amplifier two parts, and each several part is independently can divide body structure, antenna oscillator is to combine by screw and low-noise wide-band amplifier, the antenna pick-up dipole is easily lost, and causes the antenna global failure.
2. the shortest length of existing antenna pick-up dipole has increased the wind resistance in the vehicle ', frangibility within 17cm.
3. the antenna overall volume is excessive, complex structure, manufacturing cost height, function singleness.
Three, summary of the invention:
1, goal of the invention: the utility model provides a kind of vehicle-mounted combined antenna, its purpose is to solve that existing car antenna length, volume are big, complex structure, easily lose, problem that aspect such as manufacturing cost height exists.
2, technical scheme: the present invention is achieved through the following technical solutions:
A kind of vehicle-mounted combined antenna, it is characterized in that: be provided with antenna pick-up dipole, printed substrate in the housing of combined antenna, the antenna pick-up dipole is vertically set on the printed substrate and links to each other with electronic devices and components, low-noise wide-band amplifier circuit on being arranged on printed substrate.
High media components is set on printed substrate, gps antenna is set on high media components links to each other with electronic devices and components, the outside is covered with protective shielding spare; The cable that hole by housing bottom will link to each other with printed substrate is drawn.
Form helical antenna in the wiring of the two sides of substrate and constitute the antenna pick-up dipole, the lead between top layer signals and the bottom layer signal connects with via hole.
The height a of antenna pick-up dipole is 44～50mm, and length b is 20～23mm, and the total span c of antenna pick-up dipole is 30～35mm.
3, advantage and effect: its purpose of the utility model is to provide a kind of MPV onboard antenna system of suitable miniaturization, solves in the past that car antenna is that each several part independently can divide body structure, and the antenna pick-up dipole is easily lost, and causes the antenna global failure; The shortest length of existing antenna pick-up dipole is within 17cm, and it is excessive to have increased the wind resistance in the vehicle ', frangibility, antenna overall volume, complex structure, manufacturing cost height, problems such as function singleness.The utility model advantage is that antenna pick-up dipole and antenna low-noise wide-band amplifier are made in the volume that has reduced overhead active radio electricity broadcast receiving aerial in the housing, improve the water-proof function of antenna, the situation of reception can not take place to influence because the antenna pick-up dipole loses again; Shorten research and development time, the design time of vehicle-mounted antenna system, greatly reduced production cost.And the gps antenna module is installed on the substrate-printed substrate of antenna low-noise wide-band amplifier, increased function, the scope of application of antenna is enlarged, this gps antenna vertically is orientated, active radio electricity broadcast antenna along continuous straight runs orientation, therefore, make that the broadcast antenna system realizes suitably isolating in gps antenna and the active radio.
