Problems solved by technology
However, the structure of the two modules combined by welding is not stable enough, and it is easy to be affected by vibration and looseness and cause it to fall off. After a long time, it will also affect product performance, resulting in product quality that cannot be guaranteed.
And the vertical combination of two modules takes up a lot of space and causes waste of resources

The invention discloses an integrated shark fin antenna device. The integrated shark fin antenna device comprises an antenna substrate and a main control substrate, wherein the antenna substrate and the main control substrate are an integrated structure, the main control substrate is arranged at a lower end of the antenna substrate, the main control substrate and the antenna substrate are both plugged at a slot portion of a foundation of a shark fin device, the main control substrate is connected with a slot of the foundation, the antenna substrate is arranged at an upper end of the main control substrate, the antenna substrate and the main control substrate are communicated together through internal wires of a PCB, the main control substrate is connected with a power-supply power and signal transmission interface of the slot, and a signal is transmitted to a radio set of an automobile main controller. The integrated shark fin antenna device is advantaged in that the antenna substrate and the main control substrate are in vertical setting mode, the internal space is substantially saved, quantity of the PCB is reduced, cost is reduced, the antenna substrate and the main control substrate are connected without welding, signal reception interruption risks caused by solder fracture are reduced, the integrated shark fin antenna device is durable, and service life is longer.
Description
technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a shark fin antenna device with an integrated antenna circuit board. Background technique [0002] Different types of antennas are used in the automotive industry including AM / FM radio antennas, satellite digital audio broadcasting service antennas, mobile phone antennas, satellite navigation antennas, and the like. In a car, the car antenna is usually mounted on the roof of the car, in the trunk or in places such as the hood of the car to ensure that the antenna has an unobstructed view at high altitudes or towards the zenith. The most common is to support the antenna device in the shape of a shark fin and install it on the roof, which is usually called a shark fin antenna. [0003] In the prior art, the shark fin antenna is composed of two functional PCB modules, the wire substrate where the independent antenna oscillator is located and the main control circuit ...
